From the High Sierra all the way down to sleeping on the sofa after a friend's house party. The Ascent ACL from Sea to Summit is an adaptable and comfortable sleeping bag that strikes a perfect balance between weight and warmth. Sea to Summit's Ascent™ Series of sleeping bags offer more space than an original mummy bag configuration, yet still, retain the thermal efficiency we all yearn for when heading up above the tree-line.
The Sea to Summit Ascent™ Series offers everything a standard range of sleeping bag does in droves, however, they showcase several intelligent ideas to exaggerate the efficiency and practicality of the bag in many circumstances. For example, the free-flow triple-zip design ensures you're chosen sleeping bag model offers the maximum warmth and efficiency when you're in need, but also offers a number of ventilation options if you are a hot sleeper. Its half zip on the right-hand side of the bag provides freedom of movement and space for your arms, alongside additional ventilation and the potential to roll down the top third of your bag and use it as a quilt. On the opposite side, the full-length, two-way zip transforms the bag into a full quilt, whilst a sperate foot zip gives the potential to stick your toes out of the bottom. A real all-rounder.
For those really cold nights, all the zips can be closed, and the cord locks pulled tight to drag everything in close to you, assuring all of your body warmth stays where it should. Insulated with a generous allocation of high quality 750+ Loft down, you can sleep assured that the only thing that'll be waking you mid-slumber is the sound of a thunderstorm rolling in, not the cold. Whilst you're tucked up snuggly for a night in the hills, the Ascent ACL provides all of the warmth of a higher spec bag but provides more adaptability and space. Oversized draft tubes prevent your body heat from escaping, whilst the paneled foot box and 3-dimensional hood make sure you’re not compressing the down when you’re trying to stay warm.
With a vertical baffle construction over the chest section of your bag. The down insulation inside cannot move or migrate to other areas of your sleeping bag whilst in use. A side block baffle construction maintains the 60/40 fill ratio, keeping more down on the top of the bag for maximum insulation.
For someone who wants one sleeping bag that will perform wherever they take it, the Ascent ACL is the multi-purpose sleeping bag of choice.
