BEST FOR: Canoe and kayak trips.
THE TEST: Big Agnes claims that its new synthetic insulation repels rain and condensation and pulls sweat vapor away from your body to keep the bag drier and you warmer. To test those claims, we sent the bag sea-kayaking in perpetually soggy British Columbia. “The Shoestring SL was always dry in the morning, even when the tent was soaked with condensation,” wrote one tester. Cut and stitched into vertical baffles, the bag’s insulation is impressively lofty and compressible. So much so that one tester was convinced it was down filled.
THE VERDICT: A bit portly for fast-and-light trips but ideal for dank adventures of any other stripe. 22˚; 2.9 lbs.
WARMTH-TO-WEIGHT RATIO: 3
