Great fitting pair of undies. Highly recommended.

Definitely my favorite pair of undies. So cool and comfortable. I'll have to get seven pairs so I can wear them everyday of the week.

Super comfy! Light and breathable and the material feels soft on my skin. The puns make me smile and the slogans make me wiser one undie at a time!

I really, really love wearing your smartass undies. They are super soft and very comfortable, I like the wide, very cool looking waistband without a tag on it, I find tags irritating. It also makes a difference to my day to wear undies which have a cool message written on them. Another good thing is how quickly they dry and are pleasant to wear even when it’s very hot which is often a problem for me when I train, but not in your smartass undies!


I love smartass undies they both look and feel fantastic.  In addition to their fun and inspirational messages, the undies are soft and practical to wear.  They make the perfect gift!
