Marmot Trestles Elite Eco 20° Sleeping Bag

The Marmot Trestles Elite Eco 20° is a men's-specific synthetic bag that fills out the Elite Eco line at the milder end — 0°C comfort, -7°C limit, suited to late spring through early autumn. The HL-ElixR Eco fill is recycled and PFC-free, and horizontal shingled baffles combined with a differential cut help the insulation wrap the body evenly without cold spots. At 1,077 g it reaches a warmth-to-weight ratio of 6.5 and roughly 154 g per degree of range — a clear step up from the base Trestles 30°, though still behind down. A left-side full-length two-way zipper, an adjustable draft collar, and a draft tube limit heat loss, while an internal pocket holds small items overnight. Both shell and liner use 40D nylon ripstop, more abrasion-resistant than the thinner fabrics on the Elite Eco 0° winter model, which makes this a practical choice for three-season backpacking where the bag will see some sliding around on a sleeping pad.
