Devold Breeze Plus long johns are made from slightly thicker fibers than the classic Breeze long johns. They are made from 100% high-quality merino wool, which has been hand-selected for its quality, and offer exceptional softness and breathability, but are also durable enough to be the first choice for any outdoor activity. The natural properties of merino wool regulate temperature and wick away moisture, keeping you cool on warm days and warm on cooler days. Wear these long johns in summer and winter alike, simply adding an extra layer as needed. The Breeze Plus long johns are itch-free and super soft, with a relaxed fit designed for adventure. Thanks to its antibacterial properties, you can wear merino wool multiple times without washing it—just let it dry and air out, and it will remain odor-free.
