Pilled within 3 hours of first wear
My toddler is a pretty chill guy who isn’t hard on his clothes at all, so I’m surprised to be here writing this review! He wore these for the first time today on an easy/casual outdoor walk and I noticed pilling had appeared when I took his shoes off to get in the car at the end. The pilling is on his calves, so the only thing I can think of is that his boots brushing/hitting the opposite leg as he walked could have done it? He did climb on a few rocks but honestly I expect toddler pants from REÍ to be able to handle some gentle bouldering. Beware of this delicate fabric - my kid only wore them for a few hours and they already look snagged and worn.
Buy these pants!!
These pants are amazing! They are light weight, comfortable and easy to layer for colder weather. We had to buy a second a pair as our daughter only wants to wear these pants to forest school.
Great for anything
Here to buy the next size up because these pants are great, whether on rainy hikes or just at the playground
Lightweight pants for kids. Work well for running and protection in the weeds.
