I bought these at chainlove even though the reviews bashed the lettering. I didn't care about the lettering and bought them anyways. As expected, the lettes came off during the first ride. Not in the wash, but while riding. No biggy, I was expecting it. Wore them two more times in the next month. After the third ride I noticed the chamois stitching was pulling out. That is no bueno. The chamois was hanging down in the back after the ride. I wash according to their instructions on their website BTW.
I have emailed their customer support as directed by chainloves email response since they only honor a warranty for 30 days, and will see what Castelli has to say.
