Ease of Setup: 1 handed in the dark - no problem. ez setup

Had this tent for about 8 years now, and it is still my go-to tent no matter what the conditions.

I've used it on the beach, desert, mountains and in the snow in the middle of winter. Performs great and has stood up very well to the many trips its been on.

Would definitely recommend.


I have owned two of these tents for about seven years.

Rating: rated 3 of 5 stars
Design: four season convertible freestanding except for the vestibule
Sleeps: 2
Ease of Setup: easy to set up by one person. Especially if you have the footprint.
Weight: seems about 6-8 lbs.

I have owned two of these tents for about seven years. Extremely sturdy in windy conditions, I have only had to put out the additional guy lines once or twice in extremely exposed locations.

The zip-out door is a nice feature, as it gets the door out from under your knees when entering the tent and gets less wear and tear.

A big vestibule, but you can't use it for much more than boots and a pack because of the low overhead. When there is condensation on the fly, it is hard to reach the zipper at the foot of the vestibule without getting your head or back wet from the inside of the vestibule. With the vestibule door open the rain can come straight down into the tent body door.

The rain flap over the zipper rear door is not particularly storm proof. You learn to set up to protect the flap from being in the wind. On one tent I have actually glued the flap down, sealing in the zipper to create a more stormproof fly. I only seam to use the front door anyway, and the only time the back door gets opened is for ventilation.

On the first tent we had issues soon after buying with water coming through the floor, even with a ground cloth. Sierra Designs inspected the tent, and found nothing wrong, but I convinced them to give me a new one. The second tent still has this problem, but to a lesser degree. The water comes through in hard rains where heavy equipment (your pack or you) are resting on the floor. You also need to seam seal the floor/sidewall seam.

Rain coverage and ventilation can be improved if you change the stakeout method. Instead of fastening the fly straps to the underside of the pole grommets, put your tent stake through the fly strap, then through the tent stake strap and into the ground.

The convertible option for the tent is convenient and useful.

Wish it came in a less jarringly visible color, although it is always bright and cheerful inside even on overcast days.

I bought this tent as being the best of the ones available at the time. I'm not sure I would buy it again.

Average minimum weight specification is based on tent, rainfly and poles only. Clip-Locs at intersecting poles sections increase structural strength by 60% without losing flexibility or adding weight. Converts to 3-season use with removable ceiling and door panels and removable pole sections. DAC Featherlite SL poles are stronger and weigh less due to extruded construction and the elimination of insert connections. Exclusive Inter-Locs attach rainfly guy points to tent canopy, creating an integrated guy system that increases the tent's strength. Fastpack option allows poles, rainfly and footprint (sold separately) to be used together without the tent body to create an ultra-light shelter. Features one large vestibule, two removable Stash Doors and DAC Featherlite SL poles. Full-coverage rainfly features a vent to allow airflow, even in bad weather. Huge mesh ceiling and door panels provide excellent ventilation and allow stargazing in clear weather. Includes stuff sacks, stakes and guylines. Integral vestibule features a clear vinyl window with taped seams and provides gear storage space protected from the elements. Interior mesh pockets are waterproof against the sidewalls; your stuff stays dry and visible. Non-wicking stake loops and fly attachments eliminate the possibility of wicking water into tent. Reflective guy-out loops enhance low-light visibility; noiseless zipper pulls eliminate that annoying jingle when it's windy. Removable stash doors can be left at home to save weight and space; they can also be stashed in internal mesh pockets. Sewn-in floor stays taut to provide maximum usable space; heavy-duty polyurethane coating and factory-taped main seam keep out water. Steep sidewalls shed snow and rain, making this tent a reliable choice for mountaineering and backpacking. This freestanding, three-person tent easily converts from a 4-season mountaineering shelter to a 3-season backpacking oasis.
