I've been a great admirer of Etxeondo kit since I "discovered" it about eight years ago. It's made in-house in Spain and the quality of the carbon mesh jerseys and shorts (no longer available except in bibs for men) has been impeccable. I've put one jersey though at least 200 wash cycles and while the color has faded in the CA sun and the elastic around the waist loosened, the stitching was remained firmly in place.
This particular jersey I've only worn once. However it was a ride yesterday across central Washington's Kittitas Valley and up a US forest road 3,000 feet on a hot day--so therefore it was put through the paces. Be aware that this fabric is very "stretchy" and adheres to your form. I'm 6', 205 lbs and wore an XL. Probably for all their jerseys XXL is more suitable for me but vanity confines me to order XL. Anyway, the plus is that I was never conscious of wearing the jersey--it's like a second skin but it is designed and most suitable for warmer weather riding--which means salt stains will be very visible (and the boldness of the color scheme will make it more apparent) and that might be somewhat off-putting for some--esp. if you want to visit make a lunch stop somewhere mid-ride. The tightness of fit means for me that accessing the pockets requires more effort--which I don't really like. One thing I've noticed about more expensive jerseys is that it's easier to adjust the zipper with one hand and this didn't seem to a problem with the full length zipper here either.
No idea if the longevity of the jersey will match my collection of carbon fiber woven ones. I think it does feel like high quality, but if you're one a group ride an not really fit you might be self conscious about the fit--comfortable, but somewhat revealing. I don't have one, but I've heard the "1976" jersey line conforms more to the "club cut" ideal.
I think I like this jersey and it worked very well for me yesterday, but it's not going to be a "go-to" everyday one for me.
