Why we like it It’s strong enough to handle wintry conditions, but light enough to carry all year.
Protection An autumn snowstorm on Colorado’s Independence Pass didn’t faze Stormlight testers, who watched snow and sleet slide off the 75-denier polyester fly as if it were waxed. In a sense, it is: Welded seams, a thick polyurethane coating, and a special dying process that nets improved UV protection make the fabric feel (and perform) like a fisherman’s slicker.
Durability Super-tough, 150-denier nylon on the floor resists abrasion and punctures, and 75-denier polyester walls (on both the canopy and fly) stand up to canine paws. The hard-duty fabrics increase weight and bulk, but it’s a fair trade for hard-camping hikers.
Livability Three pads just fit across the 67-inch-wide floor, but headroom is generous, thanks to steep walls and a vaulted ceiling; a trio of 5’11” testers reported adequate space. A couple with a dog said that the 41-square-foot floor provided them “tons of room to spare.” Two huge doors let campers enter and exit without contorting, and two vestibules (10 and 5.5 square feet) offer sufficient space for boots, packs, and cooking, though gear in the smaller zone blocked the door. Bonus: It pitches fast thanks to color-coded poles and guides.
Ventilation The unusually thick, heavy fly traps heat—a boon on chilly, high-alpine nights. But its extra warmth doesn’t make it extra steamy: Minimal condensation collected in most conditions, thanks to mesh walls and two fly vents. $349; 5 lbs. 14 oz.; marmot.com
