Isobel Stout
Great versatility

I'm a restless sleeper and run hot and cold several times a night.
I love how this bag lets me hang limbs out and then cuddle back up inside. There's plenty of room for thrashing about and putting a mat inside the sleeve means I don't get parted from my ground insulation. I haven't used it in really cold weather though and probably won't!

Nick Duval-Smith
Interesting idea, but...

This zipless bag looked cool on the video, but wasn't practical. No way of tightening the hood, or securing the big flap around your shoulders (the wee catches half way down are not enough) and the foot flap tending to gape and let in cold air meant we are sending it back and going for a more traditional design.

Why choose us?
