Details & Specs
If a double-sized sleeping bag filled with R.D.S certified 750+ loft ultra-dry down doesn't get a non-camper into the outdoors for a night under the stars, then there's probably no hope. The Amplitude Am3 from Sea to Summit has room for two and features multiple zips for the ultimate in couples sleeping versatility.
Rectangular, 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° this bag is better suited for those who feel the cold or for chillier conditions because when it does get chilly you can zip it up and pull in the drawcords for a cosy night of sleep. In the warmer months, the multiple zips allow you to stick your limbs out or use it as a quilt.
To prevent cold spots, there are vertical baffles over the chest, while the side block baffles keep the down at the top for ultimate insulation and warmth. You can also stash your phone or other valuables in the large internal security pocket, and connect this bag to a sleeping mat thanks to the adjustable webbing loop system.
Whether you’re kipping in your van, heading to your favourite camping spot, or staying in huts – the Amplitude Am3 Double Sleeping Bag from Sea to Summit will keep you warm and comfortable.
