Instead of a zipper, the bag features an oversized, integrated comforter that wraps around you like a duvet at home. You simply tuck the edges under your body, which allows for more natural movement and eliminates the struggle of getting in and out of a traditional mummy bag.

Yes, the bag includes a dedicated sleeve on the underside that secures your sleeping pad in place. This prevents the bag from sliding off the pad while you shift positions, keeping you insulated from the cold ground throughout the night.

The bag has an EN Comfort Rating of 26°F and a Lower Limit of 15°F, making it a reliable choice for most 3-season backpacking trips. If you tend to sleep cold, we recommend pairing it with a sleeping pad that has a high R-value to ensure you stay warm near that 20-degree mark.

The bag features a self-sealing foot vent at the bottom. You can simply stick your feet out to dump excess heat quickly without needing to unzip or adjust the entire bag.

The 800-fill DriDown is treated to resist moisture, meaning it retains its loft and insulating properties much better than untreated down if it gets damp. This is a significant advantage in humid environments or if condensation builds up inside your tent.

Absolutely. The semi-rectangular shape and the lack of a restrictive zipper make this one of the best options for side sleepers or active sleepers who feel claustrophobic in traditional mummy bags.
