Icebreaker says: 

Stretchy and slim-fit merino-blend underwear made with our breathable jersey Cool-Lite™ fabric, the Merino Blend Anatomica Cool-Lite™ Trunks offer the everyday support and comfort you need.

Stretchy and slim-fit merino-blend underwear made with icebreaker’s breathable Cool-Lite™ fabric, the Merino Blend Anatomica Cool-Lite™ Trunks offer the everyday support and comfort you need. These ultralight boxers feature a durable and stretchy blend of natural merino wool and TENCEL™ Lyocell that helps manage moisture in any weather. The gusseted, slim fit includes a supportive, contoured pouch and flat merrowed seams prevent friction.

Silky-soft merino and TENCEL™ Lyocell, a sustainable plastic-free lyocell, combine to create icebreaker Cool-Lite™, a luxurious fabric that naturally regulates your body’s microclimate. Inspired by nature, icebreaker harnesses the performance qualities of natural fibres to offer an alternative to clothing based on petrochemical synthetics.

Our Verdict

Thanks to the Tencel blend, the Merino 125 Cool-Lite Anatomica Trunks are impressively breathable and dry noticeably faster than standard merino. They manage moisture well during steady movement and remain comfortable even on warmer days. The contoured pouch and flat seams help avoid chafing, though I did find the cut a bit shorter than I usually prefer—personally, I like a slightly longer leg, but that doesn’t mean you do. The fabric is light and soft, though not the most structured if you’re after maximum support.
