ALPS Brands, a leading manufacturer of outdoor recreational gear and soft goods, has launched a new apparel series designed specifically for high-activity outdoor adventure.

The all-new Evolution Merino 150 series base-layer shirts are made from 100-percent certified, ethically sourced Woolmark Merino wool — the best-performing wool on the market today. The light 150 gsm fabric is comprised of premium 17.5 micron-diameter wool fibers, making the Evolution Merino 150 shirts ultra-soft and super-comfortable against the skin.

The combination of superior wool fibers and a performance-engineered weave means the Evolution Merino 150 shirts deliver maximum breathability and moisture wicking to regulate core body temperature across a range of activities and climate conditions. Worn solo, the Evolution Merino 150 shirts offer 50+ UPF sun protection — ideal for warm weather wear in open country or high-altitude environments. When it is time to don mid-layer clothing, the Evolution Merino shirts offer exceptional heat-trapping properties that are essential for cool weather performance.

Additional benefits of this premium fabric include natural stain and odor resistance as well as fast drying.

The recommended temperature range for both shirt styles is 32°F and above — making them suitable for use as a base layer in cool weather or as an outer layer in warm weather.

The Evolution Merino 150 base-layer shirts are designed with a contemporary athletic fit and come in short-sleeve and long-sleeve. The Evolution is offered in sizes Small – 3XL.
