Insulated high-quality expeditions down sleeping bag
Product description for Sea to Summit ALPINE APII – REGULAR, Fiery Red – Crimson Sleeping Bags Unisex

The Alpine APII by SEA TO SUMMIT is the first choice for extreme cold and high altitude conditions where sleeping well can make or break an expedition.

The Alpine™ Series by SEA TO SUMMIT combines the most technical sleeping bag features to deliver reliable performance while cocooning you in the highest quality Rsd 850+ Loft Goose ULTRA-DRY Down™.

Designed for high altitude mountaineering and arctic conditions, the contoured mummy design delivers efficient insulation, while the updated expedition sizing provides space for extra clothing to be worn inside the bag. The anatomically shaped and oversized footbox can comfortably accommodate boots when necessary.

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.

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 Free-Flow Zip system provides a half zip on the right side of the bag to provide freedom of movement for both arms as well as additional ventilation. The full length, two-way left side zip provides easy access and extra ventilation options.

The waterproof yet breathable NanoShell™ fabric provides protection from wind and moisture. The tightly sized and carefully panelled hood fits snugly around your head, allowing you to maintain maximum warmth with minimal adjustment.
