Merino wool offers many advantages. The antibacterial effect of the Merino wool fiber prevents odor formation without chemicals - through its natural properties alone. The lightweight, flexible material feels like a second skin and keeps you warm naturally all over your body. Benefit from these wonderful properties of the Jockey Merino Collection - which can also be combined as a merino underwear set. The Jockey® Merino Thermal Long Johns keep you cozy and warm as close-fitting, long merino underwear with sewn-on elastic band, slightly narrowing legs with narrow cuffs at the ankle – completely without an irritating side seam. The Jockey® Merino Longsleeve Shirt impresses with its breathable, soft and quick-drying Smartwool® Merino Jersey. This means that the merino shirt keeps you pleasantly warm, but doesn't scratch like clothing made from other wool fabrics. The Jockey® Merino Thermal Overknee keeps you warm, but isn't too thick. This makes the Long John Overknee Merino Longjohn ideal for wearing under clothes and doesn't weight you or the rest of your outfit down.
