The Best Summer-Weight Sleeping Bag

We all think of ourselves as hardcore backpackers, game to handle any weather, any conditions, any mileage. But there’s something refreshing about the heady return of warmer weather. And when you start to plan out the next backpacking trip that doesn’t involve snow or plunging temps, you might want to consider adding the new Sea to Summit Spark Spi sleeping bag ($299) to your wish list. The bag has one of the better warmth-to-weight ratios on the market thanks to its overall smart arcitecture. The 850-fill down is embraced by micro-weight 10D shell and 15D lining with a one-third-length zipper and sew-through baffling to keep the weight down to a modest 12.3 ounces. Better still, the goose down has been treated with moisture-repelling Ultra-Dry Down, one of the new-ish treatments that’ll keep you warm even if the pack gets wet. At a temp rating of 46 degrees, it’s more suited to summer outings, rather than the variable temperatures of spring or fall. But its nominal weight could work well for cycle touring, adventure racing, and warm-weather backpacking And you can also always use it as a booster bag for when you do head out in sub-zero temps—because we know you really are that hardcore.
