What do the capilene numbers (1,2,3,4...) mean?

Best Answer Responded on

They're relative measures of warmth, only relevant for measurement against each other. The Capilene 1 is a thin wicking layer built for keeping you cool on warm days, while the Capilene 4 is a heavyweight fleece baselayer for slow moving or stop and go cold weather pursuits.

This layer, the Cap 3, will be good for high activity in bitter cold, or more leisurely activity in cool weather.
