Rocky Boy's Thermal Base Layer Top (Long John...

Rank No. #1
  • STOP ANNOYING BUNCHING & BINDING: Rocky thermals tops are perfect for wearing with bulky sweaters, jackets, ski-wear or even as cozy pajamas, because they’re crafted to stay put with a high quality spandex-based fabric, so no more worries about awkwardly bunching or binding - even with multiple layers
  • STAY DRY WITH MOISTURE-WICKING FIBERS: These thermal underwear tops feature Rocky’s signature moisture-wicking fibers that put an end to embarrassing sweat stains; Plus, they end the constant itching common with old-school wool thermal underwear, which is why fans choose them for a dry and comfortable fit that lasts all day long
  • MACHINE WASHABLE FOR EASY CLEANUP: While cheap waffle-knit thermals tend to fray and rip in washing machines, Rocky Thermal Underwear Tops are durable and machine washable, while still keeping a snug fit - so you don’t have to worry about awkward sagging (even with regular washing)
  • THERMAL TOPS WITHOUT THE ‘SUFFOCATING’ FEELING: Check out the pictures and see how Rocky Thermal Underwear Tops are crafted for active boys with versatility and close-fit openings that keep the tops firmly in place - but without the ‘suffocating’ feeling that comes with cheap, poorly-fitted necklines.
