In reply to Max Gough: sod the arc't gear, get MEC's own stuff. I've their version of an arc't soft shell jacket (shoeller) which was around the £50 mark!
The MEC on Broadway is the cheepest and best shop i've ever seen. £2.50ish gets you membership.
they do seel arc't stuff, but their own brand stuff is awesome value and offers good posing value here in the UK.
