Be prepared for the unpredictable with Sea To Summit's Ascent™ Series bags. Light, warm, comfortable and most importantly, adaptable. Offering the perfect backpacking balance of comfort vs weight, the Ascent™ Series sleeping bags have more space than traditional mummy bags, yet still provides the thermal efficiency you need when exploring above the tree-line.
If it’s warmth you’re after, zip it up, pull the cord locks tight to drag everything in, and relax in luxurious comfort. The generous allocation of high quality 750+ Loft down ensures great insulation, while the oversized draft tubes prevents your body heat escaping.
