The Marmot Trestles Elite Eco 30 Sleeping Bag is a versatile sleep system for everything from campgrounds to sleepovers. The synthetic construction is warm and machine-washable, keeping our kids warm while also being easy to clean. For cold nights outside, they can pull up the 3D hood for added insulation and pack small items inside the internal stash pocket. The Elite Eco features a more eco-friendly build with recycled materials and weighs more than a pound less than the regular Youth Trestle 30.
