Good stuff. Expensive. Quality.
Their stuff is generally hand-made, mostly made in the UK, with UK-made materials as far as possible. But that, of course, costs more. Lots of their things are limited run, so if you don't get it when it's first available, it'll sell out, and may never return.
I haven't bought *much* from them, but the things I've had have been very nice. We have a couple of their 'Action blankets', which are just nice quality wool blankets with a slit in the middle so you can wear then like a poncho. We almost exclusively use them as blankets, but the poncho-mode is handy sometimes if it's really cold.
I have their 'Micap' hat, number 3, which is a bucket hat in green cloth, made from nettles. I've waxed mine lightly, which has darkened it a bit.
The 'Iron Shirt' looks really good, but I already have overshirts that do the same job - if they're still around when those wear out, maybe I'll be tempted.
