Description

Sea to Summit Ascent AcII 15 Sleeping Bag. The Ascent™ down sleeping bag redefines what versatile means in a sleep system. Complex construction and high-quality down keep you warm when it’s cold outside, while the triple-zipper Free-Flow Zip™ system ensures you stay cool and ventilated when the weather warms.

Shaped to allow a natural sleeping position for comfort, the Ascent is light and compact enough to go everywhere your adventures may take you.

IS THIS DOWN SLEEPING BAG…? Warm enough for cold-weather use? Yes. The high-lofting down, technical hood, oversized draft tubes, and draft collar make the Ascent 25°F and 15°F true 2.5 – 3 season bags. For colder weather, you might choose the Ascent 0°F model and pair it with a high R-Value sleeping mat like the Comfort Light Insulated.

Really cool in summer temperatures? Yes. The Free-Flow Zip system means separate zippers on your left and right side and in the foot box. Open them for ventilation or to turn the Ascent into a fully-flat comforter.

Able to be zipped to another sleeping bag? The main side zipper can be zipped to the Sea to Summit Women’s Altitude, Journey and Venture sleeping bags – Regular and Long bags have the same side zipper length.
