Marmot Men's Trestles Elite Eco 30 Sleeping Bag

The Marmot Trestles Elite Eco 30 (Men’s) is a three-season synthetic-insulated sleeping bag designed for backpacking and camping where dependable warmth, durability, and sustainability matter. Built with HL-ElixR™ Eco Micro synthetic insulation and 100 % recycled polyester shell and lining, it aims to provide consistent loft and thermal performance even in damp conditions where down insulation can lose effectiveness. The use of recycled materials also aligns with environmentally conscious gear choices without compromising on core performance. Shaped in a mummy profile, this bag maximizes thermal efficiency by closely following the contours of the body, reducing dead air space and improving warmth retention. The combination wave-construction top and blanket-style bottom further enhances loft and comfort across key zones, while a 3D anatomical footbox gives toes plenty of room to rest. A full-length anti-snag zipper on the left and a short zipper on the right provide ventilation control and allow the top portion to fold down like a blanket on warmer nights. At a 30 °F (≈ -1 °C) ISO temperature rating, the Trestles Elite Eco 30 suits spring, summer, and fall backpacking trips where temperatures can dip near freezing but aren’t extreme. It strikes a balance between packability, warmth, and ease of use: compressing into a modest volume in its included compression sack and offering features such as an internal stash pocket for small essentials. Overall, the bag targets campers and backpackers who want reliable three-season performance with synthetic insulation that retains loft when wet, without the higher cost or care requirements of down.
