Anyone who's bought (and washed!) Calvin Klein underwear before... Do they shrink?

[RossGellersCat]

Feels a bit ridiculous asking this but here goes!

DH wants some "nice" boxers for Christmas so have bought him some Calvin Klein ones in an M and a L. Having measured them up against his current favourite pair of boxers the M waistband is bang on, but my worry is that if they shrink on the first wash/ tumble dry then I've spent loads on unusable pants. The packaging says "anti shrink technology" but I don't know whether to trust this! 😅

Any experiences much welcomed! Thanks all 😁

My DS has worn them for years. No shrinkage! They wash well.

Thanks @Smileybutwily! Can I ask do you tumble dry them as well? I've noticed our heat pump tumble dryer is fine for some clothing but then really shrinks others! (Despite heat pump ones supposedly being anti shrink too, but that's another thread and probably where my mistrust comes from in these situations 😅).

I always buy my husband and sons CK. boxers as a stocking filler. They definitely don’t shrink.

@RossGellersCat Ah, sorry, can't answer that one!
No tumble dryer - only Lakeland heated airer.

I'd err on the side of caution and go with the larger ones....

Our DSes wear CK boxers after I bought them for them for Christmas when they were late teens. They definitely don’t shrink and last for ages.

Thanks all. Will keep the medium ones and hope the tumble dryer is kind to them! 😊 (Unless anyone hops on the thread to tell me the first tumble dry shrank them by 3 sizes!)
