I've got a Kathmandu bag , I rate it its got a water repellant base with non slip thingies on bottom as well ( stop your mat pissing off in the night ) . Go hotter than you need as over time they loose there warmth . I use mine as a throw as too dam hot and stops the cramps . Only zip up when it's real real cold .
Only buy when on there 50% off deals , as they are over priced normally . Well worth a look anyways
