SEA TO SUMMIT Sleeping Bag Ascent AcI Regular

Light, warm, comfortable and most importantly, adaptable. Offering the perfect backpacking balance of comfort vs weight, our 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 is our sleeping bag of choice for most adventures.
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 down ensures great insulation, while the oversized draft tubes prevents your body heat escaping. The panelled footbox and 3-dimensional hood make sure you’re not compressing the down when you’re trying to stay warm.
