Kerrits sit tight n warm wind pro breeches

I just got a pair of the kerrits sit tight n warm breeches with the full seat and they are a little big so I was wondering if you could dry them and if that would ahrink them up a bit ? If that makes sense

mine never shrank. I didn’ think there was any cotton in them.

But oh I love them! They’re also my favorite wear around the house winter pants!!

Do you dry them ?
