Formidable weather calls for fort-like protection. The Fortress 3P provides just that with intelligent designs, durable fabrics and weather-enduring features. Constructed with all the same great features as Marmot Tungsten Tents, the Fortress has a full fabric canopy with durable guy outs, which add strength and stability, to endure stormy weather. This three-person tent is perfectly roomy with all the elements to provide foul weather protection.

A lot of tent for the money, not sure about winter camping
Posted by JohnnyH from Westchester, NY on 3/22/2020

Pros: Roomy, well-designed, high-quality, weather-proof tent
Cons: Not an ultralight. Heat-retention questionable

Chosen for 4-season backpacking. THE GOOD - Excellent construction, tons of useable space, headroom, storage. Huge doors & vestibules, snag-free zippers, great ventilation and guy-out loops, easy set-up, at 7 lbs. not too heavy, w/color-matched stakes, paracord, pole splint. Orange color isn't subtle, but is cheery w/sun shining thru it. THE QUESTION - Temps dropped to 26 degrees overnight, and even in winter bags my wife and I got cold. You can see thru the fabric of the tent body - it seems like a loose weave. My slightly smaller Mountain Hardwear winter tent, with all mesh zipped closed (except for ventilation), retains heat very well. By morning it can be twenty degrees warmer than the outside air. The Fortress has more interior air space for our breath to warm, yes, but I suspect the diaphanous fabric may be more permeable - great for ventilation and ounce-counting, maybe not snug enough for cold weather.
