Sleeping Gear

The Altitude™ Series sleeping bags have more space than traditional mummy bags, yet still provide the thermal efficiency you need when exploring above the tree-line. The Free-Flow triple-zip design ensures your sleeping bag retains maximum warmth and efficiency when needed and multiple ventilation options when it’s not. The half zip on the left side of the bag provides freedom of movement for both arms, additional ventilation and also means the top third of the bag can be folded down as a mini quilt. The full length, two-way right side zip and separate foot zip transforms the bag into a full quilt for when the mercury climbs higher than expected. 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. The Altitude™ also features extra down overall and THERMOLITE® panels under the foot area, to help keep heels and ankles warmer. Vertical baffles over the chest section ensure the down insulation cannot migrate or shift to the outside of the bag during sleep, creating cold spots. A side block baffle construction maintains the 60/40 fill ratio, keeping more down on the top of the bag for maximum insulation. Our tapered rectangular design gives you additional wriggle room inside the bag, perfect for a side or restless sleeper and an alternative if you find a traditional mummy shape too constricting. The women’s specific fit is wider at the hip and narrower at the shoulder and comes in two lengths.

The secret to the impressive performance is a combination of premium materials and careful design. The RDS 850+ Loft premium goose down, light-gauge #3 YKK zip and high performance 10D Nylon shell and 7D lining fabrics set the stage for superior performance. These materials are combined with a contoured mummy design for efficient insulation, and that mummy design is then tweaked for each model to best fit the use scenario. The women’s specific fit is wider at the hip and narrower at the shoulder and we’ve added extra down overall for increased warmth. The ULTRA-DRY Down™ water-repellent treatment protects the down from external moisture and condensation from the inside of the bag, virtually eliminating the negative effects moisture has on down. All Sea to Summit Down Sleeping Bags use Responsible Down Standard (RDS) certified down. The ULTRA-DRY Down™ protection also makes the Flame™ an impressive hard-alpine or adventure racing bag, where every gram is counted and down has never been a viable option.

Features:

- Women’s specific contoured mummy shape for efficient insulation - Ultralight 7D fabrics for minimal weight and packed size - RDS 850+ Loft Premium Goose ULTRA-DRY Down™ for maximum insulation value - Vertical chest baffles prevent down migration and cold spots - Ideal for mid-summer fast hikes or adventure racing - Sewn through box baffle construction to minimise weight and keep down in position - Doubles as a liner to significantly boost the warmth of a second bag
