The Arc'teryx Caliber Zip Neck is easily one of my favorite midlayers from this brand. This piece provides me with all the lightweight warmth and breathability I need for running, hiking, and snowboarding.. The material has a very unique corduroy finish that does an amazing job wicking sweat. It dries quickly as well, so all around, I am sure to remain comfortable. This shirt features a slim fit with gusseted underarms for added flexibility.
Collar zip: For ventilation, temperature control, and heat dumps
Sleeve pocket: Laminated zip for small items
How I Use the Arc'teryx Caliber Zip Neck
This midlayer from Arc'teryx suits almost all of my outdoor needs
Hiking: Tons of comfort on trails and ample breathability. It is best suited for cool-weather hikes. In mild conditions, it can be worn as a standalone layer or paired with a light shell for added wind protection.
Snowboarding:It easily functions as a lightweight mid-layer when the outside temperature is not too cold. I usually board in the spring with it solo without a shell (pic below)
Running:For running in the North (I live in Dallas, so anything down to 20 degrees), I always use a thin technical base layer, such as The Phase SL, as a base layer and a light polyester fleece, like the Caliber Zip Neck. If it's raining, I put my Gamma SL over it, as it's too bulky to fit under my Medium running shells.
