Omni-Freeze Advanced Cooling
Omni-Freeze consists of specially shaped flat yarns that facilitate the release of heat, and feel cooler to the touch, during warm weather and active outdoor adventures. The specifically shaped yarns, when woven or knit together, create Omni-Freeze, which transfers heat from a surface at a faster rate than traditional fabric. The Omni-Freeze flat yarns increase the surface area of the fabric that contacts your bare skin, which transmits heat faster and feels cooler to the touch.
This moisture transferring technology moves and disperses sweat away from the body for quick evaporation, keeping you comfortable during physical activity.
Omni Shade UPF 50+
UPF (Ultraviolet Protection Factor) 50+ fabrics protect you from 97.5% of the sun's harmful ultraviolet rays. Columbia's UPF rated clothing is specifically designed and tested to be comfortable in the hottest conditions incorporating design features such as mesh, venting and lightweight fabrics.
Flat Lock Stitching
This type of stitching creates a seam that lies flat within the garment rather than hanging from it, eliminating discomfort associated with bulky seams.
