If you plan on breaking a sweat, the Patagonia Capilene Midweight Crew will keep you cool. This 100% polyester crew-collared base layer features a wind-resistant face fabric and cozy inner fleecy layer that quickly and efficiently wicks away moisture. While this layer isn't as warm as other Merino options like the Smartwool Merino 250 1/4 Zip (our Editors' Choice award winner), it's better built for warm to cool weather.
In the past, this layer has won our Best Buy award for its great performance and durability for a low price of just $59. However, it lost its award this year to the warmer and better fitted REI Co-op Midweight Baselayer Crew (costing only $50). While the Capilene Midweight Crew is a little more wind-resistant then the REI Co-op Midweight Crew, our testers didn't like its boxy fit and scratchier fabrics. While the boxy fit allows one to wear a tank top or t-shirt underneath comfortably, we didn't find it was easy to layer with sticky mid layers in comparison to other options. That said, it works fine for its purpose. It's quite durable for gritty adventures like backpacking, climbing, rafting, and hiking. Take this Top Pick for Breathability on your next aerobic adventure into the wild!
