Boys' Rocky Thermal Underwear Set for Extreme Cold

About this item

• STAY-PUT DESIGN: Oversized jackets? Check. Bulky sweaters? Double check. Cargo pants loaded with all the essentials? Yup, even them. No matter how heavy your outer layers are, our thermals for kids stay put under even the heaviest loads.
• KEEP WARM AND DRY: Ultra soft fleece lining combined with moisture-wicking power can only mean one thing: Your little one is wearing Rocky kids underwear. No more sweaty, shivering nights — just warm, toasty goodness that wraps you in whole body comfort.
• ALL-DAY COMFORT: From morning jogs in freezing temps to chilly winter nights, our underoos are designed to keep you comfortable and warm all day long. With soft fabric that’s lightweight yet warm, it’s the kids underwear boys love.
• EASY TO CLEAN: A few wash cycles, and your long johns are toast. At least, inferior waffle-knit thermal tights are. Not with Rocky winter undies! Made from durable poly-spandex and superior stitching, washing machines are no match for their tough-as-nails construction.
• THERMALS KIDS LOVE: “Mooooom! They’re SO itchy!” Four words you’ll never hear your little one utter in a pair of Rocky boys underwear. With fleecy-soft comfort and a no-ride design, your little one will be nothing but cozy and content.
