Arc'teryx Caliber Zip Neck
Corduroy Texture That Wicks and Blocks Wind
The Polartec Classic Micro Velour Cord fleece sets this apart from standard fleece pullovers. The tight-woven construction creates a corduroy-like outer face that wicks moisture exceptionally well, looking more refined than fuzzy-pile fleece. The material dries faster than most fleeces I've worn, which makes a real difference during variable-intensity activities where sweat tends to accumulate. The cord texture also provides surprising wind resistance for a midweight fleece, blocking more air movement than open-weave grid fleeces.How Does the Arc'teryx Caliber Zip Neck Fit?
The slim fit runs true to Arc'teryx sizing and works well for running, hiking, and snowboarding without excess bulk. At just over 6 feet and 165 pounds, I wear a medium that allows a thin base layer like the Phase SL underneath. The gusseted underarms prevent binding during arm movement, and the articulated patterning follows natural body contours. The collar zip extends deep enough for effective heat dumps during high-output sections, then seals warmth when conditions demand. The laminated sleeve pocket secures small items without adding bulk.Best Between 35 and 55 Degrees
For cool-weather hiking between 35 and 55 degrees, the Caliber works as a standalone layer with excellent temperature regulation. I've worn this during spring snowboarding days when temperatures climbed into the 40s, using it solo without a shell and staying comfortable through varied effort levels. In colder conditions, this layer works well under shells like the Gamma SL Hoody. The fit is slim enough that layering over the Caliber works better than layering under it. For Texas winters down to 20 degrees, I pair this with a thin technical base layer and find the combination handles well for running.Arc'teryx Caliber vs. Covert vs. Kyanite vs. Delta
The Covert Zip Neck uses heavier Alpenex II fleece with a wool-like heathered appearance for more casual use. The Kyanite AR with Polartec Power Stretch Pro provides more stretch for climbing. The Delta AR uses grid fleece that breathes better during high-output activities but offers less wind protection. The Caliber occupies a middle ground: more technical than the Covert, less stretchy than the Kyanite, and better wind resistance than the Delta.Resale Value and Current Alternatives
For users who want a versatile fleece that performs well for running, hiking, and snowboarding, the discontinued Caliber delivers excellent performance. The unique cord texture provides better moisture management and wind resistance than standard fleece constructions. Resale prices typically range from $60 to $ 100, depending on condition and colorway. The Caliber line included full-zip Cardigan and Hoody versions with the same Polartec Classic Micro Velour Cord fleece. For current alternatives with similar performance, the Patagonia R1 Air at $199 offers comparable breathable warmth. Check Arc'teryx for current fleece options.
