Model: Women's Trail Pro
This dot-patterned, indestructible, closed-cell foam* pad gets updated this year with a thermal reflective barrier that improves warmth by 20 percent. Use it alone or to boost the insulation of an air pad in cold temps.
“It’s handy to throw down on the snow for breaks,” says one tester. And the dimpled surface is plenty comfortable for the weight and price, he says. “I laid this out after an exhausting winter ascent of Mt. Whitney, and it felt so good I didn’t even inflate my regular pad.” It folds easily for packing, but is still a bit bulky (20” x 5” x 5”). $45; 14 oz.; 72” x 20” x .75”; thermarest.com
*CLOSED-CELL FOAM A urethane material composed of millions of closed air cells that trap warmth; it’s light, tough, and affordable, but typically bulky
Merging two of the latest Therm-a-Rest innovations, this redesigned model remains the lightest 2-inch mattress in the line. Diagonal-cut foams (as debuted in the ProLite Plus mattress) are used to increase warmth, while digital pressure-mapping technology (used in medical seating) boosts comfort with targeted support and softness relative to the body’s contours. The women’s model features extra insulation in the foot and torso area for warmth where women need it most. Available in regular size only. R-Value: 5.1
