Looking for a pair in medium. Montane Prism or suchlike.

Yeah the Montane Prisms are the dog's. Not cheap at around £100 but Ive had mine for years and been using them for everything from dog walking to bivvy nights to bbqing in the snow. Really good kit.

At the other end of the scale, I have some of the ex-army ones that I think were about a tenner. Heavy and bulky, but still worth it for winter bothy trips where you're sat around in the cold before getting into your sleeping bag.

Yeah I really like the look of the Montane’s. I’ve got a pair of the ex army ones, they’re warm but bulky & the fit is enormous.
