Plush, spacious, and comfy – the Amplitude Am3 from Sea to Summit is the ultimate down sleeping bag that instead feels like your all-too-familiar bed.

Rectangular-shaped with an ultra-wide circumference, this bag provides plenty of wiggle room so you won’t feel restricted as you snooze. With a comfort rating of -8° comfort and a lower limit of -15°, it's better suited for chillier conditions. Zip it up and pull in the drawcords in colder climates, and make use of the multiple zips for extending your limbs or using as an open quilt when the nights are warm. Featuring a 30D nylon shell, 20D nylon lining, and R.D.S certified 750+ loft ultra-dry down fill - snuggle down in superior insulation.

To prevent cold spots, vertical baffles over the chest and side block baffles keep the down on top for ultimate warmth. Stash your phone or other valuables in the large internal security pocket, and connect to a sleeping mat thanks to the adjustable webbing loop system.

Be it kipping in your van, heading to your favourite camping spot, or staying in huts – the Amplitude Am3 Sleeping Bag from Sea to Summit will keep you warm and comfortable.
