Fly Zone Mens Thermal Underwear Bottoms | Knee Length Premium Waffle Knit Cotton, 4-Way Stretch…

As lore would have it, our founder's mother made him don long johns before every boot hockey game. Running, swinging, and defending would make those old waffle-knits uncomfortably hot and sweaty. They were bulky, and he hated how they were tight around the knees—not what a boot hockey player needs when he's trying to hustle on the ice. A few snips of the scissor and two cuts later, the first iteration of the Short John was born. We took into consideration everything that bothered our young boot hockey player and used that knowledge to create a new kind of thermal underwear perfect for active people. What you see today has all the benefits of traditional base layer pants but better. Awkward bunching at the knee? Overheating? Loose waistband? These are all things of the past. These thermal bottoms are perfect for both casual and active wear. Wear them under your jeans, use them as an effective base layer, or lounge in them all day long. Sir Short John's Fly Zone Thermal Bottoms are perfect for whatever the day has in store. So be sure to snap up your pair or be chilled.

• Long Johns, But Short - Goodbye, old-fashioned long johns—welcome Sir Short John! Our new thermal bottoms hit right at the knee. Overheating? A thing of the past. Bunching? No more. Riding up? Thanks to its plush waistband and double-stitched leg openings, these stay right where you need them.
• Layer Up - Our waffle thermal underwear for men are perfect for taking the edge off a cold winter morning, and a godsend in the months when afternoons warm up. They're great for lounging around, wearing under your favorite jeans, or taking to bed on a cold night.
• No Detail Spared - These thermal underpants for men feature waffle-knit cotton that provides a breathable yet warm layer next to the skin, while its four-way stretch moves with you. Sturdy, double-stitched leg openings hug each leg, protecting from the elements, while the plush waistband prevents rolling.
• Unisex Sizing - Sir Short John is a unisex thermal bottom. Both the Gold "Fly Zone" and Rose Gold "No Fly Zone" are based on men's measurements. We recommend that women order a size down from their usual size. Please reference the size chart to find the best fit.
