Marmot Women's Trestles Elite Eco 20 Sleeping Bag

The Marmot Women’s Trestles Elite Eco 20 is a three-season synthetic-insulated sleeping bag designed to provide reliable warmth and comfort on backpacking and camping trips where moisture resistance and durability matter. This bag uses Marmot’s HL-ElixR™ Eco Micro synthetic insulation and 100 % recycled shell and lining fabrics, combining sustainable design with performance that retains insulating properties even when wet—an advantage synthetic bags hold over down in damp environments. The Trestles Elite Eco 20 features a mummy-style silhouette that maximizes thermal efficiency by closely following the shape of the body, while anatomical details such as a 3D footbox and a snug hood help trap heat around extremities. Its insulation construction employs a wave pattern on the top and a blanket style on the bottom to balance loft and comfort under the body. Functionality and versatility are hallmarks of this model. A full-length left-side zipper with anti-snag slider makes entry and exit straightforward, and a short right-side zipper allows the top portion to fold down like a blanket for ventilation on warmer nights. Internal stash pockets and hanging loops add convenience for storing small items and for drying the bag after use. Rated to approximately 20 °F (≈ -6 °C) comfort for women, this bag suits three-season backpacking, car camping, and trail excursions where temperatures may approach freezing but aren’t extreme. It compresses into a relatively small volume with the included compression sack, offering reasonable packability for its insulation level, though it remains heavier and less compact than comparable down-filled bags — a common trade-off for synthetic insulation that performs better in wet conditions.
