Jack Wolfskin Funktional Tee
The merino wool used to make this will keep you warm without making you overheat, and it’s naturally antibacterial, too.
£55, Jack Wolfskin
Odlo Blackcomb Evolution
The minimal seams on this make it a chafe-free zone. The weave is highly breathable but warm enough to cope with winter chill.
X-Bionic Energizer Mk II
Ribbed channels in the weave move sweat quickly away, while compressive panels across the shoulders promote better posture.
Stylish and comfy enough to wear to the pub if you can rock the super-slim fit, it’s extremely quick-drying and seam-free.
Icebreaker Oasis Crewe
A good option if you don’t like too close a fit on a base layer – this is forgiving without being loose. It offers UV protection, too.
Mammut Atacazo Zip Pull
This tight-fitting top should be used as a base layer if you’re self-conscious about your physique, but it’s a soft and warm delight.
Icebreaker Compass Zip
If it weren’t for the zip you could wear this next to the skin. It’s soft (80 per cent merino wool) and regulates temperature brilliantly.
Brooks Dash Half Zip
A soft, standard-cut top that wicks well and features flatlocked seams. Also has thumb loops and a rear zip pocket.
Puma PWRWARM Half Zip
This is very thick so could be worn without a base layer in colder weather. Fleecy on the inside and the outer is water-resistant.
