The Exped Spica II UL is a lightweight, two-person tunnel tent with an aerodynamic and beak-like front vestibule designed for three season backpacking. Weighing just under 3 lbs, it’s a spacious double-walled tent that can be set up fly-first if required. While not freestanding, the Spica II is easy to set up with two poles that slide into poles sleeves, with numerous guy out options to anchor the tent in stormy weather.

The Exped Spica II UL is a tunnel tent with a front door, front vestibule, and rear windows which can be exposed for increased ventilation. The tent is held up with two poles that slide into sleeves along the top of the rain fly and curve to form the tunnel shape. The poles sleeves are very strong and help minimize any flapping of the rain fly in high wind. The two poles are different lengths but are color-coded so you know which sleeve to slide them into. The tent is outfitted with numerous additional guylines to anchor the tent down. They also help tension the fly as it relaxes after being pitched.
When setting up the Spica, it’s best to stake out the rear end of the rainfly, insert the two poles, and then pull on the front end of the fly to fully lengthen the shelter before staking it down. Most people will keep the inner tent and rain fly attached, except in inclement weather when the rain fly can be set up first and then the inner-tent attached inside under cover. You can’t use the rain fly by itself, however, because it pulls the pole ends in toward one another and provides structural support. The inner tent is suspended from the outer, ensuring good airflow between the inner and outer walls, while helping to minimize any condensation transfer. Several large vents in the vestibule and fly also help increase air circulation.
The rain fly made with a silicone/PU coated 15D ripstop nylon that has a hydrostatic head of 1500 mm, which is in line with most US backpacking tents in terms of waterproofing.
Once pitched, the Spica II must be further secured using guylines attached to the pole sleeves if you want a taut pitch. These are pre-attached and outfitted with line tensioners and not something that end-users need to outfit themselves. While the use of these stabilizing guylines does increase the size of the open area required to pitch the tent, it makes for a very strong and stable structure that can be pitched on exposed tent sites. .
The inner tent has solid breathable walls with a mesh front window in the door and mesh rear windows. They’re positioned up high to vent warm moisture and reduce internal condensation. An all mesh inner tent is not available, which is unfortunate if you camp in hot and humid climates plagued by insects because you can’t open the doors to provide relief.
The most convenient way to use the inner tent is to lie with your head closest to the mesh door. The front end of the tent also the most headroom with a peak height of 39″, before gradually slanting down towards the rear feet. Large side pockets are provided for gear storage on both sides of the tent. However, the inner tent door cannot be unzipped without disturbing a partner if two people are sharing the tent.
The inner tent has a deep bathtub floor, so there’s little risk of leakage if rain is blown under the tent’s sidewalls or you find yourself sleeping on a dished out tent site. The floor has a hydrostatic head of 10,000 mm, making it about five times more waterproof than most of the tents manufactured by US companies.
The interior of the tent is also quite comfortable, with steep sidewalls and good headroom. With a peak height of 39 inches, you can sit up comfortably at the front of the tent. But for all practice purposes, the most comfortable position is lying prone with your head facing the front door.
In warmer weather, you can roll the rear of the rain fly up over the pole sleeve to expose the screened mesh window at the rear of the inner tent. If you’ve positioned the front of the tent into the wind, you can roll open the front vestibule and get great airflow through the top of the tent.
The Spica II UL has a front vestibule with a center zipper. While it can be staked out as a structural component to help keep the tent erect, you’re best bet is to stake out the guy lines anchored on the pole sleeves for this purpose instead. This makes it possible to keep the vestibule doors rolled back or partially deployed without affecting the tent’s stability.
When closed, the vestibule helps deflect wind away from the tent, as long as you can point it into a breeze. But storing bulky gear like backpacks under the vestibule can make entry and exit awkward since you have to exit through the center of the vestibule door. If it’s blowing rain, you’ll also get soaked if you try to exit the tent at night because the sides of the vestibule will brush up against you.
Exped makes another tent called the Cetus II UL, which is virtually identical to the Spica II UL but has an extended front vestibule with a side door. It’s a much better vestibule design in terms of gear storage, weather protection, and ease of entry and exit. It also provides a good place to cook if you’re pinned down in bad weather. The Cetus II UL is much more complicated to set up and guy out, in addition to being 0.6 lbs heavier, but I find the Spica’s vestibule unworkable except in good weather when one or both sides can be rolled back.
The Exped Spica II UL is a double-wall, 2 person tunnel style tent, designed for three-season use. Weighing just under 3 lbs, it has a pointed vestibule with a center zipper which makes it awkward to use in poor weather. A better vestibule design would use two zippers instead, like the vestibules on the Hilleberg Nallo 2 or the Warmlite 2R tents. While well ventilated, if you can pitch it into the wind, the Spica II UL also lacks an all mesh inner tent for use in hot and humid conditions.
The Exped Cetus II UL is virtually identical to the Exped Spica II UL, except for the addition of an extended vestibule with a side door. That’s the tent I’d recommend over the Spica II UL, although it also lacks an all mesh inner tent for warm weather use.Editor's note: Help support this site by making your next gear purchase through one of the affiliate links above.
