My son-in-law is a lobsterman and needs extra-warmth underwear when he is on his boat. He wears this underwear everyday in the winter; takes them off at night, throws them in the washer & dryer and puts them on again the next morning. I bought him an XXL as he does put them in the dryer.
Relaxed fit, I like that, not tight, clingy and overly stretchy. Long tail stays tucked in bicycle pants. WARM. I've used this as a base layer under nylon jacket in low 40s. Also, as mid-layer between polypro' tee, & nylon water resistant jacket in upper 30s and light rain.
This item is a mainstay for my winter bicycling wardrobe. I'll likely buy a 2nd. A bargain like this won't last long.
