Carhartt Men's MBL113 Base Force Midweight Base Layer Classic Crew

I’m 5’10” and 14st. So definitely not waif like. I originally bought size large as all my clothes are size large. Exchanged for medium as large was too big. Also bought another one as it’s a really good quality warm and comfortable base layer. I wear this with a Buffalo special 6 outer layer and am good on a dog walk to about 2° C.

This is for my partner to use while riding an ebike in the colder weather.

Very comfortable waffle crew that I wore as a base layer underneath on a cruise to Alaska. In some pretty cold climates it kept me incredibly warm under outer layers — the kind of warmth you notice when you’re actually out in it, not just sitting indoors. Fit-wise it runs a bit large. I got XL Navy and there’s a little extra room, which is fine for layering (easy to slip a jacket over), but if you want a snug base-layer fit you may want to size down. Comfort is excellent; the waffle fabric feels solid and durable and doesn’t scream cheap polyester — it held up well through a full trip of cold-weather wear. It’s a bit pricey compared to drugstore thermals, but for the quality and how warm and comfortable it stayed on that trip, I think it’s good value. I’d buy this Carhartt Force waffle crew again for cold-weather layering.

Husband works outside this is brilliant for him

I find them to be a little bit short in the sleeves but otherwise as expected. A good medium base layer.
