Review: Grabbed these for kiddos to help keep them warm on Halloween. They are super soft, with little details that make them look finished, and my kids loved them so much they wanted to wear them as pyjamas - I think that says it all. Lol.
Review: Product arrived earlier than expected and appears to be good quality. My son says they're very comfortable. Size charts need to be cleaned up, there are 5 different size charts shown throughout the posting leaving it a guess what size to buy, I bought medium for my 9 yr old boy and it's a shade loose.

## Features

- 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

*by N***E on 10 January 2021*

In the past couple of months, I have purchased 4 pairs for my son. Very soft fabric - he loves them. My main issue is shown in the image with the quality of the workmanship. This specific pair arrived right before thanksgiving and it already has a hole in it around the waist band. Not happy about this because these are not cheap purchases.
