Marmot Women's Trestles Elite Eco 30° Sleeping Bag

The Marmot Women's Trestles Elite Eco 30° is the lightest of Marmot's Eco-series women's synthetic bags at 1041 g, rated to -1°C comfort and -7°C limit under EN ISO 23537 — a genuine three-season bag rather than a cold-weather one. It uses the same recycled HL-ElixR Eco fill as its Elite Eco siblings, inside a 20D recycled polyester ripstop shell with a 20D recycled polyester taffeta liner, both PFC-free. At a warmth-to-weight ratio of 6.7 and roughly 149 g per degree, it trades some per-degree efficiency for lower absolute weight compared to the colder-rated 20° Eco bags — a fairer comparison is against other 30°-class bags, where its build and weight are competitive. The full-length left-side two-way zipper allows venting, and an insulated draft tube runs its length; a stuff sack and storage sack are included. The spec sheet is leaner on hood and footbox details than other bags in the line. Packing to about 16.8 L, this suits warm three-season backpacking and summer trips where the lighter weight is a real advantage.
