Light, warm, comfortable and most importantly, adaptable, offering the perfect backpacking balance of comfort vs weight, the Sea to Summit 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.


The Ascent AcI sleeping bag - long model is suitable for use from late spring till early fall and for people up to 183 cm tall. With a tapered rectangular shape to allow a natural sleeping position for comfort, this Sea to Summit bag features a triple-zipper Free-Flow Zip system that ensures you stay cool and ventilated when the weather warms. If it’s warmth you’re after, close all the zips, pull the cord locks tight to drag everything in, and relax in luxurious comfort.


The generous allocation of high quality 750+ Loft Ultra-Dry down ensures great insulation, while the oversized draft tubes prevents your body heat escaping. Thanks to the Ultra-Dry down technology the sleeping bag is protected from external moisture and condensation from inside the bag virtually eliminating the negative effects moisture has on down. The panelled footbox and 3-dimensional hood make sure you’re not compressing the down when you’re trying to stay warm. 


The Ascent AcI sleeping bag is the lightest and most compact model in the Ascent series from Sea to Summit. It provides a comfortable shape, with more space than that the typical mummy bag and is suitable for both for camping and backpacking when you are looking for luxurious comfort and effective protection from the cold.
