Drop it down to 15 degrees and you're looking at chattering teeth through the night...unless you've brought along your Solar Flare. Waterproof-breathable Drizone keeps 600-fill goose down dry and lofty in even damp environments. Tuck stitching in the continuous baffle construction lasts for years and denies moisture an exposed seam to exploit. You'll sleep better and wake up warmer with Pad Locks to keep you atop your pad. The Solar Flare's brother model—the Trade Wind—won Outside's "Gear of the Year" award in 2006. See what the hype's all about!
