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 - providing ultimate sleeping versatility for couples. 

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°, it's better suited for chillier conditions thanks to its easy zipper and drawcords mechanisms for a cosy night's sleep. In the warmer months, the multiple zips allow campers to exend their limbs beyond the sack, or use it as an open quilt.

To prevent cold spots, vertical baffles over the chest and side block baffles keep the down on top for ultimate insulation and 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 Double Sleeping Bag from Sea to Summit will keep you warm and comfortable.
