These are very comfortable and cool to wear. Prevents chafing when wearing dresses. They have been a godsend in this hot weather. They wash well too!

Soft, breathable, comfy

I bought the black 9-inch leg in a large to accommodate my pregnancy bump. They are really silky soft and breathable, exactly what I wanted to avoid chafing. They are a little loose on the thigh as I am usually a medium, but it doesn't make them any less comfortable and means I will hopefully be able to wear them throughout the pregnancy and post-partum. If they made a version for periods that was super absorbent or had a pouch for a reusable pad, I would buy even more.

Perfect anti-chafe shorts!

Really soft, light weight boxer shorts, they come to a good length to prevent chafe and are a lot cooler than my sports shorts
