Warm and Comfortable Thermajohn Long Johns
Love the Thermajohn boy’s ulta soft thermal underwear long john set with fleece lining. Everything about this set is perfect. Made from Polyester and Spandex. The color was bright and did not fade in the wash, nor did it loose its shape. My grandson wears a large, so this would fit a size 8 to 10. The fabric is lightweight, soft and smooth. It is not tight fitting and the inseam is perfect. The lining does not make him itch. I like the wider neck to make it easier to pull on and take off without stretching. The shirt does actually lay nicely below his waist, which is very nice, so his back isn’t exposed. I also like that the wrists and ankles aren’t tight fitting. The lining keeps him extra warm in cold climate. We live in the Midwest, so this set is perfect to wear under his clothes when playing in the snow and cold outside or just to wear around the house. He didn’t feel restricted with movement either. He wasn’t sweaty after being in the cold weather, and he wasn’t cold, he felt very comfortable. He is already asking for another pair to wear while one pair is in the washing machine.
Quality
THERMAJOHN Junior Boys thermal set. This top and bottom set seems to be of good quality. Fits my seven-year-old son like a glove. My son wore the long underwear out on a snowy day and came in toasty warm. It seems as though this side is going to do its job.
Perfect
Ordered an xl for my 10 year old . He is average height and weight . I would say this product runs a bit on the small side. It’s the perfect fleece Lined thermals for the freezing New England weather Super soft and stretchy and comfy. The only thing I noticed is it’s started to thread in knots on the Arms where it rubs the most .
