I have never really spent a lot of money on biking clothes, but this year it was a mistake. I was making due, biking a lot and got saddle sore. Not pleasant. So I spent the money on a Coeur kit. I LOVE it. I have ridden it for 40 miles several times with no issues, no pinching, nor burning. It feels like my second skin. I wanted the sleeveless but that was out of stock. No worries at all. I got the small, it fits great on my 5'3, 110 lb frame. I may have been able to fit into an XS but I am a 32 D so that may have gotten too snug. LOVE this kit!
