Working together for 12 years, Designer and CEO Frank and Josh have innovated a way to solve the common problems of typical Long Johns. Wearing traditional Long Johns/base layer has a few inherent problems. They tend to bag up at the ankle, causing rubbing issues when wearing boots or skiing. They also do not provide a tight seal between the pant and the sock, allowing cold air to enter the openings when the pant slides up and or the sock slides down. Long Jayne's all in one sock thermal pant completely eliminate these issues with seamless comfort.
