Perfect and worth every penny

Purchased for my boyfriend who is a plumber and works in new construction homes during NY winters. He’s been wearing them everyday since they’ve arrived and loves the set. Said they are the warmest, most comfortable long Johns he’s ever had in his life! I’ve washed them a few times and they snap right back. If your thinking about grabbing a set I highly recommend it. Definitely worth the price.

Hubby, loves them.

Got these for the hubby, he loves them. says they are soft and so comfortable, his new favs.

Good quality

Bought for my husband. They are super thick and soft but he complains that they ride up due to a short seam in the crotch. Still wearable for factory work


My husband was surprised they kept him warm. Very soft and comfortable fabric
