Ladies, I realize this is a big purchase but SO worth it. If you haven't tried a one piece (onsie), now is the time. You won't be sorry when you slip into the highest quality fabric we offer. It is so soft, smooth against the skin and flatters all your wonderful curves with our highest level of compression. There is no tops riding up or shorts bunching, just a piece that fits you like a glove. It's all I race in now and I'm telling you, it is NOT hard to take off to pee. I race for time and I have no problem spending 10 extra seconds pulling it off. With the zip, you just take off the shoulders and drop. I timed it and I must say I would rather be seconds longer and have an incredible onsie to race in than the two piece. But that is me :-) Also this fabric is water resistant and SPF. Try putting water on the fabric and it will NOT penetrate to the skin. Instead it beads off, keeping you and the fabric dry. The SPF just another added bonus of this piece. A must have Ladies.
