Marmot Trestles Elite 20 Long (-7C)

SKU: M15442

The Marmot Trestles Elite 20 Long is an extra-long 3-season synthetic sleeping bag designed to provide dependable warmth and comfort during cold-weather outdoor adventures. Its generous dimensions make it particularly suitable for taller sleepers who need additional space without compromising the insulating performance of a mummy-style sleeping bag.

The sleeping bag uses 100% recycled HL-ElixR Eco synthetic insulation, which provides high loft, a soft feel and reliable warmth. Synthetic insulation is particularly practical for outdoor conditions where moisture may be present, as it continues to provide insulation when damp.

The entire construction uses 100% recycled polyester, including the outer fabric and insulation. The outer shell is made from recycled polyester ripstop for durability, while the recycled polyester plain-weave lining provides a comfortable interior.

A full-length left-side zipper with an anti-snag slider makes entering and exiting easy. The additional short zipper on the right side allows you to increase ventilation, adjust the opening and create a more relaxed, blanket-like sleeping configuration.

The combination of wave construction on the upper section and blanket construction underneath the body helps maximise loft, warmth and comfort. The insulation is arranged to provide effective coverage while maintaining a comfortable sleeping environment.

The anatomically shaped wrap-around footbox provides extra warmth around the feet while offering a roomy space for natural movement and comfortable positioning during sleep.

An insulated draft tube helps reduce heat loss around the zipper by limiting the movement of cold air into the sleeping bag.

For practical organisation, an internal stash pocket provides convenient storage for small essentials such as a headlamp or contact lenses. The included storage sack and compression stuff sack make the sleeping bag easier to transport and store.

The Trestles Elite 20 Long is ISO tested and designed for temperatures below freezing. It has a comfort rating of -4°C, a limit rating of -11°C and an extreme rating of -31°C.
