The blue shorts I bought last summer (13), & the red version I just got...two different shorts indeed! Be aware, the red shorts pictured on this page are not the shorts I received...totally different!
Most notable differences:
Chamois now is thicker, with a sort of 'divited' surface...interesting concept.
The 'newer' version has wider leg bands, with a color on color graphic. Also, it has a 3 small silicone grippers on the inside thigh area only; whereas the older style has a sort of built-in gripper type material on its leg bands.
The older pair has flat-lock seams that are sewn flush to the shorts both inside/out. The newer pair's seams are not sewn flush (on front side) to the shorts inside, nor the interesting 'look' on the outside as previous years' version...most importantly, will these non-flush sewn seams be a comfort issue...will post after I get come actual wear in these...still way to cold to ride in shorts in my area at this posting (still snowing!). Will up-date.
The newer version has a longer inseam: 8" for the blue ("13"), and 10" for this latest pair (this is measuring, un-stretched, from the center of the crotch to the leg ends, size XL).
But this new pair losses a full point for lack of detail and construction of the inside seams, and another point for the annoying placement of a large 'textile' tag placed on the OUTSIDE back of this garment!!! Was this a mistake by Assos, or are the serious?! It will have to somehow be carefully removed, cut as short as possible without cutting garment...then there will still be a apparent 'stump' of a tag left! Almost enough to send back, if I didn't get a good price....but someone send a message to Assos...what's with the outside tag, and the seams that aren't any better than a low-end short!
