Whether you’re headed to the beach or hiking through the mountains, this new line of performance shirts by Mountain Khakis will keep you cool and comfortable from sunup to sundown.

The men’s McKinley Polo is made with a blend of brrr° nylon/polyester/cotton fabric that uses natural cooling minerals, active wicking, and rapid drying to instantly and continuously draw heat and moisture away from your skin. With a premium branded snap closure and lightweight construction, the McKinley Polo is the perfect match for an active lifestyle and easily transitions from work to play. There’s also a men’s McKinley Sun Hoody for those days when you need a light layer of warmth, or some extra protection when you’re on the water or under the sun.

For a more polished look, the men’s Vista Short Sleeve Shirt is a technical marvel. The Vista is packed with features like venting at the back panel, a flip-and-snap collar for extra sun protection, and a built-in chamois sunglasses cleaner stitched into the side seam. Made with a brrr° nylon/spandex blend, the Vista offers plenty of stretch for freedom of movement. The Vista is also available in a long sleeve.

Ladies will love the versatile McKinley QTR Zip, a quarter-zip pullover made with brrr° performance fabric in a nylon/polyester/cotton blend. With contour seams for a flattering fit and modern style, the pullover is perfect for yoga, hiking, long runs or running errands.

All of the Mountain Khakis brrr° shirts are chemical-free and offer UPF 50+ sun protection, and they’re machine washable. Unlike other products that use sprays and coatings to achieve a cooling effect, brrr° cooling technology is a permanent part of the fabric so the cooling sensation won’t ever fade or wash out over time.
