Description

<p>For those who find ordinary sleeping bags too narrow and comfort sleeping bags too heavy, Sea to Summit has the perfect solution with its Altitude AtI. With its narrower, rectangular cut it offers more space than mummy sleeping bags, but finds the right balance between comfort and weight. This, as well as its clever construction and practical details, make it a great all-rounder that makes you feel comfortable even at sub-zero temperatures. As a ladies sleeping bag, it is also slightly narrower at the shoulders and wider at the hips to keep the warmth inside efficiently.</p><p>The 3-Zipper-System alone gives you all possibilities. In addition to the classic two-way zipper on the left, there is a second half-length zipper on the right. So you can open the Ascent AcII at the top, so that on warm days more air gets to your body, on cold mornings you can leave your feet in your sleeping bag while drinking coffee and still have your hands free. By a further zipper over the foot area it can be opened also to a large blanket. Additional Thermolite® synthetic fibre makes the foot area wonderfully warm. The Altitude can also be coupled with the men's models from the Ascent series.</p><p>For optimum warmth, the cameras are held lengthwise in the chest area, so the down does not slip here. The high-quality, RDS-certified duck down is also waterproofed so that the Ascent AcII sleeping bag functions permanently even under humid conditions. 60% of the down is on the front side, 40% on the back side which ensures an optimal distribution of the insulation.</p>
