The first shorts/undies that my daughter feels confident in to wear all day to school. The lining down the leg is a game changer!

Easy to order, received the order in a couple of days. Fast and efficient, great variety.

Nancy W.

Teen loves the water, these swimmers are perfect for Nippers, the adjustable back works well, the swimmers are comfortable and fit well, she is a tall girl and needs the length the adjustable back allows.

Nancy W.

the sizing was perfect

Ma

Outstanding! Great fit and feel...yet to test the absorbency but so far very happy with this company. Fast and prompt delivery too!

Danneale K.

These were fantastic!! They fit perfectly and being shorts, they didn't move during the night which made for added protection.

These were great for my teen under her dance costumes. They fit perfectly and gave her the confidence and reassure while she performs!

Haven't tried yet but when my daughter tried them on for sizing she was absolutely in love with how soft and minimum they feel ("perfect" were her words). She's looking forward to having her next period now for the first time :D
