Thermal Underwear Set for Boys - Long Johns, Base Layer for Ski & Extreme Cold

When winter strikes, you'll be wishing you had a pair of Rocky thermal underwear. Made with just the right blend of poly-spandex, they're the perfect balance between stretch and no-ride staying power. With ultra-light construction and cutting edge heat retention, enjoy cloud-like comfort all day.

Lightweight, yet warm; thin, yet luxuriously soft. Whether they're building the perfect Frosty, skiing or bundling up during a snowstorm, our thermal underwear is the perfect way to keep them warm and active. ROCKY EFFORTLESSLY LOCKS HEAT TO BRAVE THE ELEMENTS WITHOUT FEELING BOGGED DOWN.

Fabric type: Fleece lined. Care instructions: Machine Wash. Origin: Made in the USA and Imported.

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.
