The Treeline Sleeping Bag from Sea to Summit is the affordable down bag that’s compressible enough for backpacking yet sturdy enough for general camping.

This bag is a relaxed mummy shape, with extra space around the hips and shoulders and a fitted hood to keep your head snug. With a 2°C comfort rating and a -3° lower limit, the Treeline is perfect for three season use when conditions won’t dip below freezing. The outer shell and lining are made from 50D nylon, which makes it durable enough to take camping with the kids and even the dog. The fill is comprised of 400g of compressible R.D.S certified lofty 600+ down for warmth, and it has a two-way YKK #5 side zip with an anti-snag system so you can ventilate on balmy nights.

Heat won’t escape through the zipper as there’s a draft tube to prevent that, and you can pop your phone or other essentials in the internal chest pocket. If you’re in need of a wallet-friendly down bag for three season adventures – the Treeline Sleeping Bag from Sea to Summit is the one for you.
