Perfect Toddler Base Layer
My daughter been wearing these 3-4 times a week for the last 4 months and they are perfect in every way. We only use her other base layers if these are absolutely filthy. These are: a perfect fit for my 1.5 year old's body, soft with itch-free seams and tags, stretchy but hold their shape, easy to clean, and holding up great with washing. I would say they run just slightly large in a good way. They were a bit loose but still good for layering at first. She's now an inch or two outside of the size chart and they fit snugly without constricting.
Warm and perfect for layering
Works great to layer under Halloween costumes on those cold October nights and will work great as a layer when my little plays in the snow or goes on snowshoeing adventures with my in the carrier.
REI bring these back PLEASE!!!!
Not sure why these were discontinued since they were amazing- no tags, lightweight, not itchy, quick drying and like another reviewer said, the fit is slightly big in aa perfect way. Plus the little hiker print is adorable. So hard to find lightweight layers.... REI bring these back PLEASE!!!!
Daughter loves them.
My daughter loves these, she loves the colors and patterns. My daughter is a little small for her age, so its hard to tell, but I think these run a little big. We got the 4T size and she's about to turn 5, and they're baggy on her, they should last all ski season and summer camping season.
FR, bro! So awesome!
See my review for "REI Co-op Lightweight Long Underwear Top - Infants'/Toddlers'" bro. These are totally worth the purchase, broheim!
Please make more colors!
We love these!! Great fit! Wash well! (we always air dry) Super soft and warm but not too much.
Perfect pajama and base layer
This was a perfect set to use for pajama and a base layer for the mornings.
