Product Info

For long backpacking trips, you need to make sure you've got the right bag. The Sea to Summit Altitude™ 25 Sleeping Bag is a the warmer weather 2.5 season bag in the series that, much like Forrest Gump's magic shoes, will take you anywhere. With 750 loft down insulation and two big ventilating side zips, it keeps you warm on cooler nights and cools you off on warmer ones.

ShapeA wider shape between hips and knees to allow you to sleep in a natural position without compressing the insulation and creating cold spots. Shorter overall length and narrower girth in shoulders to reduce dead space and increase thermal efficiency.

Women's Specific FitSea to Summit's women's specific bags feature a distinctive shape designed to provide more comfort and the best thermal efficiency. The designs are ideally suited to a woman's shape - slightly narrower in the shoulders and roomier through the hip area. Down distribution is perfectly matched to ensure the torso and the foot areas are kept toasty warm.

Free Flow ZipThe half-zip on the right side of the bag (left side on women's bags) provides freedom of movement for both arms, additional ventilation and allows the top third of the bag to be folded down as a mini quilt when the mercury climbs higher than expected.
