In reply to ACollins:
Wigwam polypropylene socks if I can find them. Comfy, surprisingly odour resistant, quick drying and last f-o-r-e-v-e-r.
Pod for sacks (until recently).
MSR for liquid fuel stoves. Overpriced but reliable and last forever.
Lowe Alpine dryflo wicky-knickers. Comfy and last forever. Ditto tops.
Smelly Hellys for long John (very cheap at Screwfix!!!!)
Marmot down jackets. Solid but lightweight and stand up to treatment.
Montane for pertex and pertex and pile clothing. Slightly better design than the competition.
Any industrial clothing supplier for polypropylene inner gloves (couple of quid per pair).
Local charity shop for thin white cotton shirts for alpine summits.
