I'm already a big fan of BabyLegs since diaper changes are much easier while providing warmth. But now that my kid is a stumbling walker/runner, I was forced to use pants even during very warm spells - enter BabyLegs Cool Mesh!! Not only do they supposedly provide sun protection, they help protect the legs.

These aren't as thick as your regular BabyLegs, as expected. And like all BabyLegs, they do slide down and expose the knees. Sure you can cut off old crew socks or tights instead of buying BabyLegs, but those are even worse about staying on, even with BabyLegs' sliding-down issue.

The one-star deduction is because I personally think the classic BLs are a better value because you mostly use these indoors, and if it's so hot, you wouldn't need these nor the SPF capacity. But I suppose if you don't want to use sunblock on your little one's legs because s/he absolutely can't avoid the sun for some reason, these would be a good option.
