Marmot Fortress Tent: 3-Person 3-Season

Add Protect+ Powered by Extend™

Why We Like The Fortress Tent

Built for backpacking trips with a small group, the Marmot Fortress 3-Person 3-Season Tent comes equipped with all of the best features of the top-selling Tungsten Tent, but also a full canopy and additional guy outs to help handle stormy weather. Spacious and sturdy, this tent comfortably fits three spaciously thanks to the zone pre-bend design and vertical walls, while the burly, treated fabrics do their part to repel water in a downpour. Furthering its robust construction, sturdy aluminum poles clip together with color-coded Easy Pitch clips for a quick setup. Then, the two D-shaped doors open up the flow to help us sneak in and out throughout the night, while two vestibules give us plenty of dry storage space for everyone's gear. Internal pockets help our group organize smaller items, and a lampshade pocket securely holds our headlamp to create ambient light.

Best Tent

True to size
Size Bought

I have used my Fortress 3p in all kinds of conditions. Super spacious for two people and gear. Great venting and can actually get pretty warm with the fly on. Took it to Grandfather Mt and it poured for 5 hours straight, dry as a bone inside.

Perfect tent for a backpacking family

I've put it through the wringer

Our family of four, which includes one very active five-year boy and a black lab, have put this tent to multiple test this camping season. The first test was on an early spring trip with snow still on the ground and lows in the 20’s. The tent had ample room for the four of us with Darla (our dog) beginning night at the feet of our boy and cuddling with us in the morning for some added warmth. The tent vented our condensation very well and showed no signs of wear and tear as expected. The following weekends, we canoed and backpacked into remote campsites that included mud, sharp rocks, tree roots and other tent dangers. Our tent remained in mint condition. Over Memorial weekend, we camped in unseasonable warm weather and laid in our swim suits enjoying a breeze which cooled the tent nicely as the mosquitos swarmed outside. The next weekend included several inches of rain falling as we camp next to a swelling river. The tent remained dry, despite having very wet dog dry off inside as we played board games in this spacious tent. We look forward to more adventures with confidence that the tent will protect us.
