The MacPac 300 SF was designed for adventure racing and alpine climbing.

Pertex® Endurance® shell and fully taped seams make this bag extremely resistant to outside moisture. This also enables you NOT to carry a waterproof bivy sack, which is considerably lighter compared to a separate down sleeping bag and waterproof bivy bag.

A 14" water resistant left side zipper allows easier entry and ventilation. Two part multi-adjustable hood keeps heat in. Waterproof vacuum seal stuff sack is a dry bag and sleeping bag stuff sack combined. Mesh storage bag is also included.
