Merino wool is a natural choice for base layers: it's soft, itch-free, stretchy, and its built-in moisture management buffers well against sudden temperature changes. You'll appreciate its anti-microbial properties. So will your tentmates.

We've picked a fabric weight that works well under your other layers year-round. And we've styled it so that you can reach overhead without baring your midriff.

• Made of 100% mulesing-free New Zealand merino wool.
• Four-way mechanical stretch.

• Ribbed collar and cuffs.
• Machine washable with about 6% total shrinkage.

Fit guide

Technical garments, designed for specific activities have features that aren’t always adaptable to general use. For example, cycling clothing is longer in the back and arms. Activity aside, the fit of MEC clothing falls into these categories:

Body fit: tight, with no room to spare.

Slim fit: very close fit, with a bit of room.

Regular fit: generous, but not oversized.

Relaxed fit: oversized with lots of room for layers.
