New Zealand outdoor performance apparel brand Macpac has a new line of long-sleeve T-shirts, short-sleeve T-shirts, button-front hiking shirts with pockets, sleeves, neck gaiters, and other items made with brrr° cooling fabric to keep to cooler and more comfortable wherever life takes you.

The new line from Macpac featuring brrr° cooling fabric includes a variety of men’s and women’s apparel, including stretchy versatile T-shirts in both long-sleeve and short-sleeve options that are made for outdoor adventures, summer hikes, and long days spent outside.
The shirts have UPF 50+ sun protection where the fabric covers the skin, with underarm gussets and criss-cross flatlock seams on the sides that are comfortable against the skin and offer superior mobility and freedom of movement while hiking or wearing backpacks and running vests.
The long-sleeve shirts have a regular cut, with slightly longer sleeves that offer maximum coverage while minimizing bulk. The women’s shirts have a slightly streamlined cut for a flattering silhouette.

Made with brrr° polyester and Elastane for stretch, the Macpac T-shirts are machine washable and the brrr° cooling effect is permanently embedded in the yarn of the fabric so it won’t fade or wash out over time. brrr° combines the powers of natural cooling minerals, active wicking, and rapid drying to create a “Triple Chill Effect” that instantly draws heat and moisture away from your skin. And brrr° continues to cool you down as long as you wear it for all-day comfort.
The Macpac long-sleeve and short-sleeve T-shirts are also finished with Polygiene StayFresh™ technology that uses silver chloride sourced naturally from water and soil to prevent the growth of odor-causing bacteria while keeping unpleasant smells under control.
For hikers and outdoor enthusiasts who prefer a more utilitarian shirt with pockets, Macpac also offers brrr° nylon button-front shirts for men and women that have a classic shape with upper back venting that’s mesh lined, an extendable collar, and button up cuffs. On the left chest pocket, there is a discreet zipper to store essentials. Made with brrr° nylon, the long-sleeve button-front shirt has a regular fit and reviewers say it runs a little small so please consider sizing up.

Macpac’s brrr° collection also includes lightweight summer sleeves that you can pull on or off for a cooling effect that also offers UPF 50+ sun protection — perfect for hiking, paddle boarding, kayaking, fishing, and other warm weather activities. Made with brrr° polyester and Elastane for stretch, the sleeves have gripper dots on the palms and a discreet thumb hole to preserve your dexterity and functionality while wearing them.
The Macpac brrr° neck gaiter is another must-have for cooling power and UPF sun protection. With a tube-style versatile design, you can wear the gaiter to protect your neck or turn it into a headband to protect your scalp and hairline from sunburns.
The gaiter is made with brrr° polyester to draw heat and moisture away from your skin, and a touch of Elastane for stretch and to ensure a snug fit. The gaiter is also treated with Polygiene StayFresh™ technology, which uses silver chloride sourced naturally from water and soil to combat odor-causing bacteria.

All products in the Macpac brrr° collection feature brrr° cooling fabrics, which are independently tested by third-party labs to prove their superior cooling, wicking, and drying capabilities. brrr°’s patented technology is permanently embedded inside the yarn on the fabric so it won’t ever fade or wash out.
We’ve been partnering with Macpac for several years, and we love to work with another company that is as passionate about performance cooling fabric, UPF sun protection, durability, and sustainability as we are.
Started in his family garage, Macpac founder Bruce McIntyre had a vision of creating innovative outdoor apparel that was designed, tested and proven in the ultimate outdoor test lab — the rugged and climates of New Zealand. He wanted to engineer the highest quality equipment that would get you anywhere and back again, with the best comfort and performance.
