Keeps Warmth In, Moisture Out

Getting out on the trail has never been easier. A collaboration with Kelty, the SBX 20 sleeping bag keeps everything you loved about the SB 20 and swaps in premium synthetic insulation, making the price more accessible for a wide range of campers and backpackers. This insulation is quick drying, hypoallergenic, and insulates even when wet—so you can still wake up feeling rested after a rainy night. The 20d nylon ripstop shell and 20d nylon taffeta liner keep the weight fairly low, while a number of technical features provide warmth and waterproofing. Rated to 20 degrees Fahrenheit, this bag is suitable for spring-to-fall use. 

Note: At checkout, choose men’s regular, women’s regular, or men’s long (+ $10). The first 500 purchases will come with a complimentary Kelty Camp Pillow ($20 value).

First-Run Production Perks

When you join a drop before it goes into production, you’ll get some exciting perks:

  • Kelty Camp Pillow ($20 value)
  • Q&A with Kelty product team
  • $10 credit toward your next Massdrop purchase


This mummy-shaped bag will keep you wrapped in comfort. The box baffle construction ensures the insulation is evenly distributed and stays in place throughout the night, maintaining its loft and warmth. The thermal-fit hood and top draft collar help seal out the chill, while the natural-fit foot box gives you enough room so you don’t feel constricted. At the hood and foot, you’ll find Kelty’s innovative Head-2-Toe Dri waterproof protection: a strategically placed treatment that prevents condensation and moisture from penetrating the bag. Crawl in, zip up the 60-inch dual-slider locking zipper, cinch the drawcords, and you’re ready for another snug sleep under the stars.
