Marmot Trestles Sleeping Bag

Yes, the Trestles is rated for 15°F, making it a solid choice for three-season camping. Because it uses SpiraFil® LT synthetic insulation, it retains warmth even if it gets damp, which is a major advantage over down bags in unpredictable, wet conditions.

The bag features a fold-down second zipper that allows you to open the top of the bag like a blanket. This is particularly useful on warmer nights when you want to regulate your temperature without fully unzipping the bag.

This specific model has a maximum user height of 66 inches, or 5'6". If you are taller than this, you will likely find the bag too short and should look for a long version or a different model to ensure you can fully extend your legs.

The anatomical 3D footbox is shaped to follow the natural position of your feet while you sleep. This prevents your feet from compressing the insulation against the shell, which keeps the loft high and your toes warmer throughout the night.

At 4.5 lbs, this bag is on the heavier side for ultralight backpacking. It is better suited for car camping, short hikes, or basecamp setups where weight is less of a concern than durability and warmth.

Marmot included an anti-snag slider on this bag specifically to address zipper issues. While no zipper is completely immune to snagging, this design significantly reduces the likelihood of the fabric catching while you are getting in or out.
