b'SLEEPING BAGS AND PADSRest EasyComfortable, technical, lightsleep systems for every seasonBY STEPHANIE PEARSONAND RYAN STUARTSea to Summit Ascent AcII $399Weve seen the trend in jackets and tents, and now its come for sleeping bags: weight savings, warmth, and comfort are no longer at odds. Sea to Summit loaded itsAscent AcII with niceties, like an oversize shape that ac-commodates all sleeping positions and three zippered openingsfull-length on one side, half-length on the other, plus a slit around the footboxto regulate temperature. It boasts 19.4 ounces of750-fill down, with a mix of vertical and horizontal baffles that keep the insulation in place and prevent cold spots, and a large draft collar to lock in heat. The result is ano-compromise sleeping bag that weighs just 2.4 pounds. Its much roomier than most light bags, but still toasty warm, said one tester. On a backpacking trip in British Columbias Chilcotin, we found it true to the 15-degree temperature rating, but the easy venting system meant we slept great at 60 degrees. Thats an impressive range, especially for such a feathery bag. Sure, there are cozier options. But we have yet to find a worthier bag for three-season use. 2.4 lbs44OUTSIDEBUYERSGUIDE2020 | HIKE AND CAMPSBG20_HIKE_GOYSleepingBags&Pads_rlsd_446275.indd 44 3/27/20 1:47 PM'
