Sea to Summit Trek Down Sleeping Bag

The Trek Down Sleeping Bag is built for travelers who don’t want to sacrifice comfort for packability. Featuring a tapered-rectangular mummy shape, it offers more room than traditional mummy bags, making it ideal for side-sleepers or those who prefer extra space.

With dual zippers, one full-length and another at the foot box—you can ventilate easily or fully unzip the bag into a cozy down comforter. Filled with high-quality down insulation, it ensures warmth without bulk, and the design compresses easily into your pack.

Available in a Regular Wide option for added comfort, the Trek is perfect for trekking, backpacking, and all-around outdoor travel.
