REI Flash 60 Women’s Backpack Review

REI Flash 60 Backpack Review
The REI Women’s Flash 60 is a ventilated multi-day backpack that’s lightweight but doesn’t lack for features or convenience. Weighing just 3 lbs and 5 oz, it has an adjustable-length frame and women’s-specific shoulder straps and hip belt that will fit comfortably across your chest and mold around your curves. REI also sells a lower volume version of this pack, the REI Flash 45, in both men’s and women’s-specific models.

Backpack Storage and Organization

The Flash 60 is laid out like a conventional multi-day backpack with a top lid, large main compartment, open front stuff pocket, and side water bottle pockets. It has two mesh hip belt pockets and a zippered pocket on the outside of the stuff pocket that’s great for storing odds and ends that you need to keep track of.

The top lid or brain has a large roomy pocket. That’s where I like to keep a few extra snacks and my hygiene kit. The top lid is floating and attached to the pack using straps, so you can raise it up if you need to overstuff the main compartment or pile more stuff on top of it. The lid is well-shaped and doesn’t slide backwards down the back of the pack, like some top lids do, even when it’s packed full. There’s a second mesh pocket on the underside of the hood with a key fob. This is where I store my first aid-kit, out-of-the-way, but still easily accessible.

The main compartment is large and has an internal hydration pocket, with ports over each shoulder to run a hose. There isn’t a separate sleeping bag compartment, but I’m good with that and don’t really see them as necessary on a 60L pack, although they can be useful on larger ones. In addition to top access, the main compartment has a J-shaped zipper that runs around the stuff pocket and provides access deep into the main compartment so you don’t have to unpack everything to pull out something stored in the bottom of your backpack. I probably wouldn’t use this much because I line my backpack with a trash compactor bag to prevent the contents from getting wet in rain, but I could see its utility for travel or if you hike in a drier climate.

The side water bottle pockets are large enough to hold Nalgene bottles and are easily reachable when I’m wearing the pack. They are made with a lighter weight mesh though, so durability might be an issue if you hike off-trail a lot. If you’re not careful, items stored in the side pockets can fall out when you bend over. My advice would be to keep loose items in closed storage and just use the side pockets for water bottles that are easily noticed if they fall out.

The hip belt pockets are made with the same mesh and large enough to store snacks, a compass, or a cell phone. I prefer hip belt solid pockets, because they’re more durable, water, and moisture resistant, but there’s an easy workaround for that: wrap sensitive electronics in sandwich baggies when it’s damp.

The front stuff pocket is large enough so that I can store my crocs and rain gear in it. It also has a drain hole at the bottle to facilitate the drying of wet gear. I keep my map, bandana, and PLB in the zippered pocket on the front of the stuff pocket, so they’re quickly accessible. This is a great place for a pocket and really adds to the pack’s utility,

Backpack Frame and Suspension

The Flash 60 is a ventilated backpack with a suspended mesh back to keep your back cooler and help dry perspiration more quickly. While the back of the pack is slightly curved to create a cavity behind the mesh, it’s not large enough to interfere with packing, which can be an issue with some ventilated backpacks.

The frame is also adjustable so you can adjust the torso length to fit your measurements exactly, even if you’re between sizes. To lengthen the torso range, you lift the shoulder strap yoke which is connected to the pack with velcro; to shorten it, you lower the shoulder pad yoke. It’s so easy to do and lightweight, you have to wonder why all backpacks aren’t set up this way.

The hip belt and shoulder pads are pre-curved to fit “the” female chest, while the hip belt is flared to provide a better wrap over the tops of female hip bones. There’s a modest lumbar pad at the back of the hip belt to prevent it from slipping and to direct the load to your hip girdle. But it’s barely noticeable and quickly forgotten. The hip belt also adjusts with a pull-forward mechanism which makes it easy to tighten.

The Flash 60 has load lifters, which help pull the load closer to your back so more of the weight is on your hips and not your shoulders. They work in conjunction with the aluminum wire frame, that has a top cross-piece for additional stiffness.

Backpack Compression and External Attachment System

The Flash 60 has a unique “Uplift” compression system that pulls the contents of the main compartment up over the hip belt, raising your center of gravity, and pulling the load closer to your back so you can carry a heavy pack more efficiently. It’s really remarkable.

But the straps used to implement the Uplift system aren’t really set up to attach gear to the side of the pack like more conventional compression straps. For instance, to secure long objects like tent poles in the side pockets. While you can “kind of” make them work that way, the diagonal orientation of the strap is not as secure as a horizontal strap would be.

Lots of external attachment points

There are straps at the bottom of the pack however that you can strap a tent body or sleeping pad to. This is a nice feature, often left off lightweight backpacks, but very handy. In addition, there are two ice axe loops, trekking pole tip grips, and upper tool keepers to secure tools and poles.

The women’s REI Flash 60 is a great pack.  I’m very impressed with the features and overall fit, considering its modest price. But it wasn’t until I had the pack loaded with weight and items that I felt the benefits of the simple compression system.  REI really did an excellent job creating a torso hugging fit, while maintaining a wide, top loading, easy to access pack. When you add in the fact that the Flash 60 has an adjustable length frame and ventilation; it’s available in torso sizes down to 15″, and has female-specific shoulder straps and a hip belt, it should definitely be on your short list of lightweight women’s backpacks. I think you’ll be impressed.

  1. I had an older version of the flash. I liked it ok, although this looks like an upgrade from several years ago. If I had two wishes for this pack they would be to remove the vertical zipper on the front stash pocket, which I had slide open on a trip and nearly lost my snacks (!) and the water bottle pockets from the flash 45 implemented on this as well. I love that new location, it makes so much sense that I’m not sure why REI didn’t embrace it on all their flash models.

  2. I’ve used the 1st gen. REI UL men’s pack for 2 years and the somewhat better 2nd gen. Cruise UL pack for 4 years then got my current Osprey EXOS 58 and LOVE its comfort.

    REI makes good stuff. Last week I bought an REI FLASH Insulated air mattress (& Sea to Summit pump bag) and am happy Now have a very light shoulder season mattress with and R3.7 rating – a rating I trust.

  3. Thank you for this great review. I just purchased this backpack for half price! I am a complete novice regarding backpacking,so I constantly research everything and find the choices overwhelming,to say the least. I read your review and just decided to buy it because I trust what you have said. Now maybe if I can decide on a tent I will actually get out there and use it:)

  4. I just found one for my daughter on eBay, which seems to be the only source since it’s discontinued. Philip, note that the amazon link at the bottom of the article goes to a different product, some Anime art. A good price, but not so useful for backpacking.. :)
