Its two-layer offset construction reduces cold spots, while an insulated chest and zipper baffle help limit heat loss during cooler nights. The bag includes a durable polyester ripstop outer shell paired with a soft polyester liner for comfort and long-term use, along with a #8 separating zipper for reliable operation. It compresses down for efficient storage in the included compression stuff sack, making it suitable for backpackers needing a balance of warmth, packability, and durability.
