Ascent AcII Sleeping Bag: 15F Down

The Ascent ACII Sleeping Bag from Sea to Summit is a lightweight and compact sleeping bag that can be easily packed down to the size of two water bottles. Don't let its small size fool you, though - this sleeping bag offers reliable protection in wet environments. Its 15-degree rated 750-fill down insulation is treated with a hydrophobic Ultra-Dry treatment, ensuring that it retains its warmth even in damp conditions caused by condensation inside the tent.

Designed for three-season use, the Ascent ACII Sleeping Bag features a unique zipper system. One side has a full-length zipper, while the other side has a half-side zipper, allowing for increased ventilation on warmer nights. Both zippers and the shaped hood are equipped with draft tubes, providing solid coverage and protection against wind.

In addition, this sleeping bag includes an internal pocket for storing phones and electronics. It also comes with an Ultra-Sil compression bag and storage sack for convenient packing and storage options.
