Absolutely fantastic customer service. Shopping for clothes online can be challenging, but they have virtual fittings to help with sizing, and really good return and exchange policies. The materials are high quality and comfortable. I've bought a variety of different things (including bras, leggings, pajamas) and while not everything has been a keeper, I'm a repeat purchaser of the ones I really like. I can't speak to the leakproof products, as currently I'm fortunate not to need them, but I'm a regular wearer for over 3 years now of the wireless bras and tank tops.
