Features

  • Fleece
  • Made in the USA and Imported
  • Pull On closure
  • Machine Wash
  • 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): Dont 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 boys 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

    • Warm and Comfortable
Color: Black Size: X-Large
We bought these for a recent ski trip to Oregon where we knew the temperatures were going to drop really low: These were great as a base layer. They are warm and soft almost like fleece on the inside of the garment and smooth and silky on the outside. They really kept us super warm and at the end of the day my kids didn't want to take them off because they are so comfortable! Great purchase! Very happy! ... show more

    • Comfortable and Warm
Color: Black Size: Medium
We used these on a ski trip as a base layer under ski pants and a ski jacket. It was between 20 and 30 degrees on our trip. My child said they were very comfortable, but they got a little hot while skiing once the weather warmed up to over 30 degrees. We just unzipped the sides of the jacket to vent body heat, and it was perfect. My kids also run quite hot so it might work just perfect all day for another kid. Definitely recommend. ... show more

    • Cozy and weirdly sized
Color: Red Size: Small
I'm so on the fence about how to rate this! - My son absolutely loves these. I might buy another pair he loves them so much, BUT . . . - My MIL had to take the waist in by INCHES. He's 5 years old, about 42lbs and 44 inches tall (A lean little boy, I know). We got him the small and they fit like jammies. If I do get another pair it will be the XS so they fit better under his clothes. The waist was seriously ridiculous and there won't be a time when it won't be. If he's tall enough for the waist, the pants would be capris. Comfort is absolutely 5 stars, though. The fleece lining is cozy. Because my son's so lean he gets cold easily during our winters, and he stays toasty warm with these on. So, they do their job very well. tl;dr? I love these IF you have someone handy with a needle. ... show more

    • Great base layer for kids!
Color: Black Striped Size: Medium
My 9 yo wore these in 37 degree weather in Tahoe and was plenty warm. These thermals are extremely soft and comfortable, fit true to size, and make a great base layer. For reference, my son is on the small, thin side, 52 inches tall, about 62 pounds, and the mediums fit great with a bit of room to grow. My son loved them so much, now that we are home, he is wearing them for pajamas. ... show more

    • Too big
Color: Black Size: X-Large
I had to return these ran way too big for my skinny son (11yrs, 12/14,) I ordered xl based on other customers reviews bcse there was no size chart I could see? They were soft and cozy feeling but again just too big for him.

    • Soft and cozy but pills
Color: Cars Design Size: XX-Small
Loved the pattern options and they are silky on the outside and soft inside however after one use we did get some pilling making them less soft.

    • Soft
Color: Dinosaur Design Size: X-Small
My boys love these however the waist on the pants does seem to run large on both of my boys. The tops are nice because they fit longer and tuck into their pants. They both love sleeping in them at night and will wear them under their clothes on cold days. I know they are staying warm when they will go out without their jackets and play for an extended period of time. I wish I could give five stars, but again the sizing on the waist for the bottoms seems very large. ... show more
