Long John

Men's long johns and thermal base layers, built around the patented Joey Pouch®

Whether you're skiing, layering for the commute, or just trying to stay warm on a long flight, the 2UNDR Long John keeps you covered without the bulk or itch of old-school thermals.

The fabric is a 4-way stretch bamboo-cotton blend. Soft against the skin, breathable under layers, and warm without overheating. The Joey Pouch® keeps everything supported and separated, so there's no shifting, bunching, or awkward adjusting on a chairlift or a 12 hour drive. A roll-resistant waistband sits flat under pants, and flatlock seams disappear under your other layers.

Wear them as base layers under ski pants, as warmth under jeans on the coldest days, or as loungewear when the heat's on the fritz. Available in clean solids and signature prints, sized S to 4XL. For the warmer months, swap into men's boxer briefs or browse the full lineup of men's pouch underwear styles.

Comfort where it counts, all the way down. Stock up in our men's underwear multi-pack for the best per-pair price on cold-weather essentials.
