Sea to Summit - Women's Altitude AtI - Untuvamakuupussi

With its tapered, women-specific rectangular shape, the Women's Altitude Atl strikes the perfect balance between space and variable warmth. For optimal warmth around your feet, Sea to Summit has used extra down and THERMOLITE. Plus, the anatomical shape of the foot box maximises loft and reduces heat loss.

The 20D nylon shell packs down nice and small, and the RDS 750+ Loft ULTRA-DRY down fill delivers optimal insulation.

The vertical chest baffles distribute the down evenly and prevent cold spots.

The half-length Free-Flow zip on the right, full-length #5 YKK zip on the left and the zip at the foot box provide extra space, flexibility and improved ventilation.

The oversized draught tube, complete with anti-snag materials, prevents heat loss through the zip. For warmth around your head and neck, the sleeping bag features an oversized collar with a dual adjustment system. The Zip Coupling allows you can pair the Women’s Altitude Atl with other sleeping bags.

The Altitude series strikes the perfect balance between comfort and weight. The unique design offers more space than traditional mummy sleeping bags, but still provides excellent thermal efficiency, so you can use it whilst adventuring above the treeline.
