Most comfortable undies I've ever bought. The best way I've found to keep my passport and money secure, and they’re easy to wash and fast to dry. JanetMelbourne, Australia |
I've used the undies on two occasions to trek and found them to be very comfortable and very easy to care for. Highly recommended. DennisRazorback, Australia |
Great gift! I received two pairs for a recent trip to India and they were fabulous. Comfortable under jeans and cotton pants. Gave me peace of mind in the crowds of India. LouiseLeichhardt, Australia |
