With traditional long johns, you often sacrifice weight and flexibility for sweet, sweet warmth – and the problem only gets worse the more you layer up. To create a better base layer from the inside out, our AKHG Boar’s Nest Base Layer Pants are made with innovative hollow-core fibers that capture insulating air at the center of the fabric for superior warmth without adding weight or bulkiness. A healthy dose of spandex keeps Boar’s Nest close to your body, reducing bunching and boosting freedom of movement as you huck firewood or break trail in fresh powder. Built-in sweat wicking and stink fighting for drier, fresher adventures. Plus, flatlock stitching and a soft elastic waistband prevent painful chafing, even during intense activity.
