Alpinestars Stella AST-1 WP Pants (Size XL Only) 5 5 5 5
Great fit, comfortable I'm 5'4", 130lbs, 35-29-38. 29 inseam. Fits perfectly. Gets a little muggy inside due to waterproofing layer, but that's no surprise. Loving the fit and very comfortable. April 12, 2016
Comfortable and great fit. I have tried so many different pants before my Alpine Stars. Some are too baggy either waist or thighs. These were the first to fit my body type. I tried a medium but they were too small so I went into a Large. I am 5'3 and 140. An extra large could work too for me to have a little more wiggle room. They have stretched a little as I've worn them in over the last 6 weeks. I live in AZ so these are great for our winter, but will not work for our soon to be coming summer. I am hoping Alpine comes out with a comparable summer pant. It has taken me about a year to find a pair of pants that fit correctly. SV 650 March 11, 2016
Nice fit First pair of bike pants. I got these pants because I wanted something waterproof and protective. I originally got a size small. The small fit me slightly snug, and I wanted to have the option to wear pants underneath these, so I sized up to a medium and they fit perfectly. For reference, I'm 5'4" and 118lbs. I wear a size 6 (US) in pants normally. Very flattering pant for a great price. March 17, 2015
Finally, a pair of pants made for a women over 18! I am a slightly "older" woman rider with the shape to go with it and is hard to find a touring pant that is made to fit a thicker waistline comfortably. Most pants are cut correctly through the hips but are made for women that still have an 18 year old waist. The Alpinestars Stella, being a slightly low rider, are perfect for both. The only thing I would change is adding a leg vent. I would appreciate a bit more air circulation. I feel the sizing runs a bit small. I usually take a small or medium but had to get a large. All in all, I am thrilled with these pants. October 24, 2014
Awesome pants! I am 4'11 feet tall. (5'1 with Dainese Svelta boots on), 108lbs. These fit awesome. A little tugging over the hips but that's due to the extra padding there but they fit perfectly for my waist, not too snug, not too loose, I didn't need to adjust the velcro at the waist. I got a size XS, I usually wear a size 2 in pants. I am pretty much an XS in all A* gear because if I get a small then I start to have issues with the fit being too long or armor not sitting in the correct places. They may be just a hair too long for me but it's not really that much of an issue. The Velcro at the bottom of the legs makes sure nothing will drag. They are not super slim on me but you wouldn't want it too tight anyways, room to maneuver and I don't feel like I have to tug them up on my legs and adjust like I was with my skinny jeans. I saw way too many pictures of what little protection regular jeans gives you if you happen to be in an accident, and I like my skin attached to me so I ordered these. I just need to order some gauntlet gloves and I will have a full set of gear from head to toe. Squid no more! Haha. No regrets! September 17, 2014
