The Big Sky Chinook 1Plus is a freestanding, four-season tent that weighs 3 lbs 7 oz. It’s a double-wall, dome-shaped tent with three exoskeleton poles that can be pitched in a variety of different configurations. For example, you can set it up with three poles for maximum strength or two poles if you want to save weight, with or without its inner tent. You can also detach and pack up the inner tent on wet mornings in order to store it separately from the wet ran fly, or attach it after the rain fly has been erected when you set it up.

The Chinook 1Plus has two side doors and a very spacious interior that’s a palace for one person, but it can also fit two good friends in a pinch. By default, there isn’t any covered vestibule storage, but you can detach one side of the inner tent from the fly to create it. Realistically, the only time you’d want to do this is in rain or snow, when you want a place to store wet or snow-covered gear, or you want to cook under the cover of a vestibule.

Tent Architecture

The easiest way to set up the Chinook 1Plus is to set up the rain fly and the attached inner tent simultaneously. This will keep the inner tent dry, even if it’s raining outside.  The rainfly hangs from the tent poles with clips, while the inner tent hangs from the inside of the rainfly with tiny buckles. While you can set up the fly alone and then crawl around under it to attach the inner tent, there are over a dozen tiny buckles that have to be attached during the process, which can be a bit time-consuming. The same can be said for packing up the inner tent first and then breaking down the rain fly. It’s a valuable bad-weather option, but a somewhat more involved process on the Chinook 1Plus than on the Hilleberg Niak or the Tarptent Moment DW, which provide an equivalent option.

The most important thing you have to know about the Chinook 1Plus tent is that it sets up drumhead tight, with the poles exerting considerable pressure on the rainfly, including the side door zippers. This is good because it counters the sag that normally occurs overnight or in rain with a silnylon shelter, so you don’t have to get up and tighten the guy-out points at night. However, it complicates the assembly and breakdown of the tent a bit, because it requires a fair amount of elbow grease (strength) to get all the poles into their grommets, fly hooks around the poles, and interior connectors attached. A certain amount of dexterity is involved, which can be in short supply in cold weather, when wearing gloves interferes with fine motor skills.

Setup Options

The foot end is narrower than the head end giving the tent and a more wind resistant profile
The foot end is narrower than the head end. This is the end that should be pointed into the wind.

The outer tent has two crossing poles that slot into color-coded grommets. The third optional pole crosses them at a near 90-degree angle and slots into grommets at the bottom of the two door zippers. Despite the color coding, it can be a little difficult to get the orientation of the poles right, because the poles themselves aren’t color-coded, just the grommets. You can tell which pole is which because the two crossing poles are straight, while the third has bends in two segments. The third pole is optional but strengthens the shelter and is a good add-on in windy weather or winter if you’re expecting significant snow loads. Without it, you’d just stake out the doors, but you’ll experience some overnight sag in the fabric since the doors won’t be under the same tension as they are when attached to the pole.

Dual ceiling vents help eliminate internal condensation

There are two rooftop vents in the rain fly that act like transoms and can be propped open to promote airflow across the top of the tent. They’re angled slightly down to prevent blowing rain from entering, but can also be closed, while you’re inside the tent.

The inner tent has two mesh windows at the top of each interior door to permit air from the transom to flow through the inner tent. They have breathable fabric flaps so you can zip over the mesh to eliminate any draft. The vents in the fly and the inner tent do a great job of reducing the temperature differential that can cause internal condensation. I’ve been very surprised at how little condensation buildup occurs in the Chinook 1Plus, even at sub-optimal tent sites where I would have expected it.

The inner tent completely fills the rain fly
The inner tent completely fills the rain fly.

The inner tent has a diamond shape and completely fills the rainfly, so there is no vestibule storage space in the default configuration. If you’re using the tent for just one person, there’s plenty of space inside to store your gear. The interior is quite large and comfortable that way. If your gear is wet and it’s raining, you can create a vestibule area by detaching one side of the inner tent from the rainfly sacrificing some of your interior space for vestibule storage. This is a standard option on this kind of tent, although you see it more on European brand tents than ones from US manufacturers.

You can create a gear storage vestibule by releasing one side of the inner tent and folding it back.

You can also use the Chinook 1Plus without the inner tent to save weight, by releasing the clips and hooks that hold the inner tent in place. This can be a good weight-saving option if you don’t mind sleeping on snow in winter since the three-pole structure is so wind-worthy and strong. Alternatively, you can sleep on the fitted Tyvek groundsheet that Big Sky provides with the tent, or use it with the inner tent to protect the floor from abrasion and punctures.

You can detach the inner tent and pack it away or attach it after the rain fly has been set up to keep it dry in rain.

Inner Tent Options

The Chinook 1Plus’ inner tent is only available with a breathable mesh inner, usually reserved for cold weather or winter use. It’s quite effective at preventing wind, sand, and spindrift from blowing in under the catenary cut sides of the rain fly, but is uncoated so it breathes well.  The inner tent floor is a 30D nylon silicone/PU coated and seam-taped fabric floor with a 3000 mm hydrostatic head, so quite waterproof, with a high bathtub floor to prevent water entry.

The Big Sky Chinook 1Plus is a big tent that packs up small so it won't weigh you down on your adventures.

The Big Sky International Chinook 1Plus is a great four-season tent that’s lightweight, storm-worthy, and comfortable to use. Weighing slightly over 3 lbs, it’s also a self-supporting freestanding tent that can be set up just about anywhere, on wooden tent platforms, rock, sand, and snow without having to be staked to the ground first. Plus you can set up the rain fly before you set up the inner tent guaranteeing that it stays dry when it’s raining, That kind of flexibility goes a long way when you’re camping at wilderness tent sites and you want to pitch up quick to get out of the weather.

  1. A wrap of colored electrical tape on the pole ends is a cheap and easy fix to identify the poles.

  2. Decent Hilleberg copy I suppose

  3. I always liked the look and specs of this tent, but I have wondered about its winter usability. Having the poles exposed I fear that one morning I am going to wake up and find them frozen in certain conditions. Poles under the fly or on external sleeves seem less open to this possibility. But maybe I’m wrong or it’s easy to deal with.

    A note regarding space. The North Face Assault 2 was tiny. I’m 5’9″. When on two mats and in winter bags, alone in the tent, I would touch the walls at both ends, even on a diagonal. Being a single skin tent, my bags got pretty wet. I tried a Soulo at home, not in the field, and I was very happy with its livability.

  4. I have always been interested in their tents and noticed they have updated their website and streamlined the choices, but they still seem a bit odd, lots of items out of stock and still telling us they won’t charge the credit card until shipment. A vestige of their rocky and humble beginnings maybe? Regardless, I don’t think I have ever heard anything negative about their tents and your review affirms that. Thanks.

    • My impression is that they are just horribly inept at this internet thing. The products rock though.

      • “they are just horribly inept at this internet thing”
        Oh Phil, that is an understatement, I say this as an owner of both their Revolution 1 person and 2 person. You never get an answer from them, BUT the tents are bomber tough and the designs are excellent. I have been eyeing this for some time and it is good to see a review. To be honest I would have been surprised if it were negative. I think they may rule the world if they just worked a better way to interact with prospective clients. I have been singing their praises in Australia for a couple of years. The Chinooks are the Revolution model toughened by the over bar.

  5. Good review and photos. I had never seen the Chinook 1 person tent before.

    I have a Tarptent Moment DW with ripstop interior for 4 season camping. I also ran the optional crossing pole BENEATH the fly after shortening it 5″ and sewing double-sided Velcro cable ties beneath the fly at theX-ing pole exterior web attachment reinforcements. Works great in wind and snow load.

    I prefer the Moment DW for its fast setup speed, aerodynamics in high winds (with guy lines, natch) AND the totally sheltered inner tent door.

    My 1st backpacking tent was a Jansport wedge tent shaped very much like the Chinook and I hated the exposed inner tent door when the fly was open in rain or snow. The Chinook needs a re-designed door fly.

    Another thing I see that the Chinook needs are fly hem stake loops on the long sides to keep them from flapping in high winds and to keep snow buildup (snow slides off the fly) from pushing in the walls. It happens and you need to get out and shovel the snow away from the walls regularly – like at “zero dark thirty”.

    • The Chinook doors don’t flap. When I said it sets up drumhead tight, I meant it. With those roof vents, the need to open the side doors are greatly diminished in cold weather. I think a potential issue is rain when you open the side door. Looks like it is very easy to get drenched. Bigger gutters to redirect the water away from over the door zips would help prevent that.

      • I’d agree that the door design may need looking at. I live in Scotland and have the Chinook 2p. Whether it’s rain or condensation/dew on the fly, water easily falls into the inner tent when the doors are open, as the floor of the inner is wider than the apex. Fine for dry environments but a flaw when it’s wet or humid.

  6. I have had one of their Revolution 2p tents for several years and have used extensively in heavy rain, and winter in the snow. It is a very well made and I would purchase another. This tent looks exactly like mine except for the 1p capacity and slightly heavier material.

  7. Philip, how would you compare this tent to the Tartpent Bowfin 1?

    • The Chinook 1 plus is primarily a winter tent, while the Bowfin isn’t. The Bowfin is much simpler to set up and I believe much lighter weight (don’t have the specs in front of me). They both have two doors though, which is nice, but the bowfin has more easily usable vestibule space, since its set up by default that way.

  8. Hi Philipp –

    Thanks for the review. I’ve been eyeing this tent in the 2p version for a while as a lighter, cheaper but hopefully not too less of a robust option in lieu of a Hilleberg… Your review seems to quell that concern over quality quite a bit. I am a huge proponent of fly first set ups and seems only a few US makers do it this way.
    Anyway, a short while ago in your list of “10 best freestanding tents of 2018”, you wrote, “Exterior poles attached with hooks and bungie cords. You couldn’t pay me to test that in the wind with all of the flapping sounds it would make at night. I’ll stick with a Hilleberg where I can get a decent nights sleep. It might be fine for well protected forested sites, but then you wouldn’t need a freestanding tent.”
    Given how taughtly you say the Chinook sets up & does not flap, would you now revise that earlier remark? Thanks for your time and expertise –

    • I didn’t test it in the wind, but I did set it up with two poles (which is an option) and it’s a much looser and weaker setup. As for Hilleberg, they get a rigid pitch with two poles all the time because the sleeve architecture is that much stronger. I’d still prefer a Hilleberg over a Big Sky. There are a lot of little things about a Hilleberg that really add up when you compare them side by side. For instance, the fabric is much more waterproof, the inner tent is much easier to hang, the guyouts are much more robust, the door tiebacks work better, the floor is much tougher, etc.

  9. Hi Philip,

    Thanks for yet another great review. The Chinook looks like it might be just what I’m looking for in a “fourth season” tent. Will it replace the Black Diamond Firstlight on your winter gear list? If not, what makes the Firstlight a better choice for you? Thanks.


    • The first light is much easier to set up. Takes just a second.

    • Great information and also I would like to know if the tent materials have been treated With a flourocarbin free DWR and if the tent is pvc , Vic and fire retardant free. It is quite hard to find this info out about many tents but for sensitive campers it matters.

  10. Hi Mike from NZ here. Quick question, if you pitch small end on into the wind, wont the wind catch the fly when the vestibule door opened. Is it not better to pitch head first so can open door without wind ballooning the fly etc

    This is a great tent for taller folks. Notice the inner tent length, 91 inches. A Hilleberg Soulo is only 86 inches.

    The ends on the Chinook are near vertical too. Those extra 5″ make a world of difference for me at 6′ tall.

  12. I realize this post is a couple years old now, but it is an excellent review of a very good tent, and I just wanted to add my comment in case anyone else is looking.

    I have a Chinook 2P, which is of course slightly larger & heavier than the model Phillip reviewed here, but his comments on various qualities & details of design and construction still apply. When he says that this tent sets up “drum tight” he is not exaggerating. It can be a little nerve-wracking when you first set it up, because you do have to muscle the cross pole into place, and you will worry that the whole thing is going to snap and tear…but I have had my Chinook for a couple of years now (and it was bought 2nd hand), and it is still fine: no rips, tears, bends, or cracks.

    This thing is bomb proof, and extremely comfortable. I have had it out in long nights of sustained hard wind (I can only guess, but about 35-40mph all night, plus gusts…) and have hardly noticed. No flapping, no worries, and no gusts chilling me inside. The fly comes down quite low to keep the weather out (mine does not have snow flaps), but can be rolled up a few inches in fair weather if wanted. Combined with the fabric inner tent, it can be actually rather warm inside — a good 5-8 degrees in my experience. I have had it out in temps about zero (ambient), and my thermometer inside still read 10 degrees or more. Condensation/frost did develop on the inside, but was easily managed with a chamois cloth. I was really buttoned up on those nights.

    Anyway…just wanted to add my thoughts on a very good tent for anyone doing their research. I bought a Revelation 2P (w/porch) a few years ago and fell in love with it, and am very glad I found the Chinook.

    Big Sky’s product are top-notch, but sadly they do have a reputation for poor communication and slow product fulfillment. In my personal past experience, they have been slow to respond to a few emails; alternately, they have replied to others almost instantly. They also have a quirky website, to say the least (or more accurately “websites”, as it appears they now have a new page as they try to update their platform.) That new site is incomplete, so a visit to their “old” page is actually worth the hassle. Just grab a cup of coffee and be prepared to navigate a site that harkens back to the 90’s….

    In summary: Big Sky tents are very good. Simply be patient (but persistent) with communication, and you will not be disappointed.

  13. I’m very interested in this tent – a wind stable, 4 season tent at this weight is impressive. However, I’m not so sure about how waterproof the fly fabric is, with a HH of only 1500. I’d be using this tent in Scotland, in heavy, horizontal wind and rain. Any idea if the modest HH of this fabric would stand up to such conditions?

  14. I have the 2p version and love it though concerned about the weak guyouts.(had one rip out) Also hate how the door zips catch on the storm flap all the time when wet. I had to glue some stiffener fabric inside the flaps to stop that.

  15. The communication, delivery times and support from BigSky are so underground that one can only advise against a purchase. There is plenty of evidence for this on the web.
