Great baselayer for little adventurers!
Bought these for our little man for the colder months. He is between 4T and 3T so we opted to size up for growing room. Only issue we run into, which he runs into with most pants anyway since he's lean, is we have to roll the waistband and make sure his shirt is tucked in otherwise they slide down. He has worn these under fleece footies in his sleeping bag and slept through the night. Not as soft as the lightweight base layer from REI but a nice thicker warm layer that will work well under ski pants and fleece tops as we get into the colder months ahead.
Works great, long lasting, good cut
We got this in 2T years ago for our kid. It has lasted several years of frequent use and looks pretty unworn. Funny enough she still loves it and just barely fits into it despite being 5T and us having already bought her the same shirt in larger sizes
Worth it!
Great quality and sizing - it's hard to find the right size - 18 months. Just a few more dollars than Amazon and the material exceeds expectations. Looking forward to some great sledding! I wanted to get a set that would work for all sexes and this is perfect. The fabric is not scratchy as well.
Best long underwear for toddler
Absolutely love these long underwear for my toddler. Fit perfectly and super cute.
Great for my son!
Great for a base layer for my son. Good quality, comfy, & cute :)
Toddler shirt
Shirt is very soft and roomy. Hangs nice as a layer or alone. Easy wash and dry fabric. No shrinkage during washing. Warmth without the bulk.
Great for cold weather
These fit my toddler so well. and they did so good at keeping him warm when we took him out to the snow. kept him warm but didn't over heat.
