Hillwalking/ Mountaineering:
Generally Paramo system, Aspira salopettes, Torres gilet, Mountain Shirt and Aspira smock.
Woods: Buffalo shirt under an Artist Smock.
Merino baselayer, I'm not fussed on branding.
Socks: good quality wool mix, I usually look At well made branded socks, Bridgedale etc.
Gloves: I have several pairs of Hestra gloves which are fantastic but over the last couple of years I've started using French 'bin man gloves' made by Venitex. Excellent quality, very tough, good insulation and a lot cheaper than Hestra. A lot of Alpine guides and ski workers wear them and with good reason, they're bombproof and very good quality.
Boots: Scarva Delta Sl, flexible but tiff enough to take crampons. Scarva Fitzroy boots for winter climbing.
Arctic/ Scandinavia:
All of the above in varying layers, either Alico or Lowa Mountain boots depending on whether I'm using skis or not and a variety of handwear, I use Mountain Equipment Pro Tough mitts which I picked up from their factory shop in Stalybridge for £15. Or I use Dachsteins under the shell. For working I'll use either my Hestra guide gloves or my Army leather gauntlets.
For a hat, I have lots of beanies and I always have at least two Buffs.
