Kept my kids warm skiing. Review: Very comfortable and warm - Very comfortable and warm! My son loves these and even wanted to wear them as pajamas the day they came. The bottoms are too big in the waist, but that was my fault for ordering a M for my 6 1/2 year old. Still highly recommend them they are very warm. ## 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 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09NB2VPQ4 | | Age Range Description | Little Kid | | Apparel Closure Type | Pull On | | Apparel Fabric Stretch | Medium Stretch | | Apparel Fabric Weight Class | Lightweight | | Brand Name | Rocky | | Care instructions | Machine Wash | | Collection Name | Rocky | | Color | White | | Customer Reviews | 4.5 out of 5 stars 148 Reviews | | Fabric Type | Fleece lined | | Fit Type | Loose, loose Stretch | | Fit to Size Sentiment | Fits as expected | | Garment Size Country | United States | | Global Trade Identification Number | 00810065353566 | | Import Designation | Made in the USA and Imported | | Manufacturer Part Number | 85WXS - New Label | | Material Type | Polyester Blend | | Material composition | Fleece lined | | Neck Style | Crew Neck | | Occasion Type | Everyday | | Pattern | Solid | | Product Care Instructions | Machine Wash | | Size | XS | | Sleeve Type | Long Sleeve | | Style Name | Snug | | Style Number | 85WXS - New Label | | Unit Count | 1 Set | ## Images ![Rocky Thermal Underwear For Boys (Long Johns Thermal Set) Shirt & Pants, Base Layer w/Leggings/Bottoms Ski/Extreme Cold - Image 1](https://m.media-amazon.com/images/I/31gZVrjRDjL.jpg) ![Rocky Thermal Underwear For Boys (Long Johns Thermal Set) Shirt & Pants, Base Layer w/Leggings/Bottoms Ski/Extreme Cold - Image 2](https://m.media-amazon.com/images/I/41J13ap62JL.jpg) ![Rocky Thermal Underwear For Boys (Long Johns Thermal Set) Shirt & Pants, Base Layer w/Leggings/Bottoms Ski/Extreme Cold - Image 3](https://m.media-amazon.com/images/I/41fJUyaQJaL.jpg) ![Rocky Thermal Underwear For Boys (Long Johns Thermal Set) Shirt & Pants, Base Layer w/Leggings/Bottoms Ski/Extreme Cold - Image 4](https://m.media-amazon.com/images/I/51+gVLD8XwL.jpg) ![Rocky Thermal Underwear For Boys (Long Johns Thermal Set) Shirt & Pants, Base Layer w/Leggings/Bottoms Ski/Extreme Cold - Image 5](https://m.media-amazon.com/images/I/51F+04-VSJL.jpg) ## Available Options This product comes in different **Color, Size, Special Size Type** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ My kids love them! *by B***. on 17 February 2020* These are a great base layer: soft on the inside and silky on the outside, so a sweater slides on easily.
