Marmot Trestles Elite Eco Sleeping Bag

Yes, it is rated for 30 degrees Fahrenheit, making it a solid choice for three-season camping. Because it uses synthetic insulation, it retains warmth even if it gets damp, which is a significant advantage in unpredictable shoulder-season weather.

While synthetic insulation is generally heavier and bulkier than down, it excels in wet conditions. Unlike down, which loses its insulating properties when wet, this synthetic fill keeps you warm even if the bag gets damp from condensation or rain.

Mummy bags are designed to be efficient, but this model includes an anatomically designed footbox to provide extra room for your feet. If you are a restless sleeper who prefers a lot of space, you might still find it snug compared to a rectangular bag, but it is built to balance thermal efficiency with comfort.

This bag is designed for users up to 72 inches (6 feet) tall. If you are taller than that, you may find the bag too short to fully cover your head or comfortably use the hood.

The bag features a full-length, two-way zipper equipped with an anti-snag slider. This design is specifically engineered to prevent the fabric from catching, allowing you to get in and out of the bag or vent it easily without frustration.

Yes, Marmot uses 100% recycled polyester for both the shell fabric and the insulation. It is a great option if you are looking to reduce your environmental footprint without sacrificing performance.
