IBEX Merino Wool Mammoth Full Zip Hoodie for Men | Heavyweight Nuyarn Fleece Jacket with Helmet-Compatible Scuba Hood

The IBEX Men’s Mammoth Full Zip Hoodie is built to take on the coldest days—whether you’re skiing back bowls, climbing alpine faces, or just navigating frosty commutes. Aptly named after the mighty woolly mammoth, this heavyweight merino hoodie is powered by Nuyarn spinning technology, which transforms the natural benefits of Merino wool into a performance powerhouse: more thermally efficient, more elastic, and nearly nine times more durable than conventional wool. Designed for mountain-ready action, the Mammoth Hoodie features a scuba-style hood that fits snugly under a helmet, a two-way belay zipper that makes gear layering a breeze, and offset shoulder seams to eliminate chafing from packs or harnesses. Harness-compatible zipper hand pockets and a secure chest pocket add smart utility for ski tours or technical climbs. Inside, the hoodie is lined with a soft Merino fleece for next-to-skin comfort, while the dense wool blend exterior shields you from wind and chill. Despite its heavyweight warmth, the Mammoth remains breathable, thermoregulating, and antimicrobial, making it the ideal companion for active travel and everyday wear in colder climates. Whether you’re adventuring outdoors or relaxing après-ski, this hoodie delivers unmatched warmth, comfort, and durability—your ultimate go-to layer for cold weather.
