Fit is too small Even after measuring, the fit is WAY TOO SMALL, not even close to fitting. These pants are really not worth the effort. June 9, 2015
Awesome pants!! Just one minor issue. I bought the GP pants to go along with my Alpinestars smx plus boots. The pants work tremendously well with the boots and feel great with riding. The knee cushion and padding rubs on the top of my knee a little much. But I haven't completely broken them in yet and compression shorts would resolve that issue I believe. Over all they are amazing pants they breath fairly well and have extremely good movability. June 8, 2015
Great pants to go with my Celer jacket I purchased these to use with my A*'s celer jacket as a second 2 piece suit. I was worried about the sizing as I have a size 48 Motegi 2 piece suit and the pants are slightly short in the thigh length. However, the GP plus pants seem to be cut slightly different as the size 48 seems to be a bit tighter in the waist but looser in the knee circumference. Also, the thigh length seems to fit me better. These still need to break in but it should get more comfortable. The mesh in the pant cuffs are very comfortable in my sidi vortice boots. The stretch panel in the back seems to flow air well, so it should help with cooling even with out perforated leather. I am once again happy with another piece of A*s gear. June 3, 2015
Great value and I don't think I had to sacrifice on quality. I caught these on sale, so I got a great deal.They seem like they are high quality and inspire confidence, but I haven't raced in them yet. I am 5'7" and about 140; 30 inch waist. I wear 30/30 levis. I bought a pair in size 48,but they were too large and I exchanged them for a size 46. The fit is much better. I bought these with the intent of ordering a zipper from Alpinestars as a replacement for the zipper on my Dianese jacket to connect the two as a race suit. The pants came with both sides of the zipper to connect to the top of a two-piece race suit. I didn't have to order a new zipper. This made things easier. After a trip to the tailor they fit together fine. I am just trying to get to the track, so style wasn't a concern for me. They look the part. May 18, 2015
Good Leather Pants It is a good leather pants for the price, with a good materials, apparently with well built. If you need security for your trip and you aren´t a radical rider it will work well for you. April 7, 2015
To leather or not to leather. The size chart was right on the money with these pants! Im a small human and the regular cut falls right above the ankle on a 5'8" male. As you know, you want a tight fit to avoid floating armor or friction from leather sliding across your bum. That and leather will stretch a wee bit. They get good airflow, but that might be the responsibility of my boots pushing air through them and I wear under armor with wicking. They smell good... Get them now while supplies last! Close out means you spend money now to save it later. Cheers literate browsers. April 6, 2015
Excellent quality, great fit, awesome to ride in! I initially ordered the size that I would normally wear, and as per the size guide, when delivered it was very clear that I required the next size up. Now I have the correct size, these pants are awesome, the fit is firm enough they don't move around on you, yet flexible enough that you can move around on the bike unrescited. The pants are so well made that I will be spending some of my hard earned cash on an Alpinestars jacket to match them. March 9, 2015
Good quality leather pants Runs slightly small even at 2 sizes up from my normal pants size. Good construction and zips up with two of my A* leather jackets. March 9, 2015
