Buffalo Mountain Gear?

Anyone tried one of these?

I know several gamekeepers who use this a lot in Scottish West Coast and Islands. All swear by it. A mate also has used it in Afghan mountains.

Yeah I'm pretty sure STG guys I worked with once had the tops and they swore by them.

It's good stuff, bit different to traditional layering system.

I have both the mountain jacket and fell jacket. Never use the mountain jacket as it's too hot. Fell jacket gets alot of use hunting.
