As the name suggests the Hanwag Thermo hiking socks are designed for cold weather. They have terry loops throughout, though these are thinner on the heel, which is unusual, and are certainly very warm.

The socks are marked L and R, though I can’t see any significant difference between them. I’ve never found this matters anyway. I’ve often put the socks on the ‘wrong’ feet, usually when donning them still half-asleep in camp in the morning, and never realised until I’ve taken them off.

Chris Townsend’s verdict

I’ve found the socks comfortable and fine in cold weather. I think they might be a bit hot and sweaty in warm weather, but, to be fair, they’re not designed for that.

The Hanwag Thermo Socks fit well and stay in place as there are bands of stretch material at the heel and across the instep. The rest of the sock is quite stretchy too.

I’ve found the Hanwag Thermo socks comfortable and fine in cold weather. I think they might be a bit hot and sweaty in warm weather, especially given the high synthetic content, but, to be fair, they’re not designed for that. After wearing they do feel slightly more matted than socks with much higher wool content and perform best if washed regularly. They’re fluffy again after washing though they have pilled more than other socks with loose fibres appearing in places. How much this will affect the durability I will find out. For now it’s just cosmetic.
