The Sea To Summit Altitude At I Down Sleeping Bag – Women’s Long offers the perfect balance of a lightweight sleeping bag that’s incredibly comfortable and compact for your outdoor adventure. The Altitude series of sleeping bags boast more space than traditional mummy bags, however, they have superior thermal efficiency to ensure you’re kept secure and warm on your trip! The extra down overall and the thermolite panels under the foot area ensure you have plenty of warmth in the sleeping bag, though there are plenty of zippered sections that can be utilised to increase the ventilation as well! The generously sized hood and dual cord adjustment provide you with maximum warmth retention and there’s also a large internal security pocket to keep your essentials close. The Sea To Summit Altitude At I Down Sleeping Bag – Women’s Long also includes an ultra-sil compression bag for compact storage.
