## Features

- KEEP WARM (WITHOUT THE SWEATY MESS): Happy Customers say the unique breathable, moisture-wicking fibers on Rocky thermal underwear keeps them warm, without becoming sweat-soaked, so trips to the snow aren’t ruined by constant uncomfortable sweating and overheating
- NO MORE OLD-SCHOOL SCRATCHY INSULATED UNDERWEAR: Traditional cotton long underwear are simply scratchy and uncomfortable to wear for long periods of time, Rocky thermals are made from a soft, comfy polyester blend so you can enjoy all-day comfort, and your winter adventures never have to end
- FLEECE-LINED COMFORT (WITHOUT THE BULK): Don’t let the lightweight fabric fool you, thanks to the fleece-lined design, this thermal underwear set gives you high-quality warmth that fans say keep them warmer than traditional puffy thermals or wool base layers that leave you feeling strangled or trapped
- NO MORE AWKWARD ADJUSTING THANKS TO ELASTIC SEAMS: Check out the pictures and see how this boy’s thermal underwear set is crafted using elastic seems that keep tops and bottoms from falling down or bunching up (even on long walks to school), and if your family enjoys skiing, snowboarding, or ice skating then Rocky makes a great base layer -- but without the sagging and ‘awkward adjustments’
- MACHINE WASHABLE FOR EASY CLEANUP: While cheap Thermal Underwear unravel in the washing machine after only a few cycles, Rocky uses high-quality stitching for thermal leggings and long sleeve shirts that stand up to the washer -- even with super-active days and many muddy adventures
