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.
Hello! does the Amplitude Down Sleeping Bag come with the straps like in the S2S website photos, so it can be sinched onto a mattress? What would be the maximum width and thickness of the pad? Thank you
G'day Kelly,
The Amplitude Sleeping bag does come with the adjustable straps as in the STS website photo, these button onto the sleeping bag to help secure this over a mat. They are adjustable, a large single mat is about 201cm x 64cm, I would say the approximate maximum size of a mat for this sleeping bag connected with straps would be about 70cm wide and 8cm thick.
does this come with the stuff sack & mesh bag?
G'day Nils,
Yes, all Sea to Summit down backs come with a mesh storage cube, and a stuff sack. Obviously it's best to store the bag uncompressed in the mesh cube between trips, and only use the stuff sack when you're away.
If I purchased 2x of these can they be zipped together?
Yes, you can join two of these together, they are also compatible with other 'Zip Coupling' bags from Sea To Summit.
