Alpinestars Stella Oxygen Air Pants 3 5 2 2
Nice fit and overall look, but lacking in the protection features I am 5'4" and 125 lbs and got the medium size which actually fit me perfectly and I was happy with the overall look of the pants. The fabric has a really nice look to it. I also chose these because I wanted a lighter summer pant to wear over jeans, and I liked the boot zipper that extends all the way up to the knee. The only part of the pants I am not happy about is the knee protection. It is not a hard plastic armor, but kind of a thick rubber, and unlike advertised both in the video, and on the product tags, the knee protection is not adjustable to fit to the placement of your specific knee. In the product tags it even says that you are supposed to use the velcro to adjust the armor to fit you, but there is no velcro, there is just an integrated pocket where the pad goes. As I mentioned earlier, the length and fit were perfect, yet the knee pads still sit too low and do not cover the knee at all, but rather the shin. I really wanted good integrated knee armor so I will be returning these. October 12, 2015
Not Great I was hoping to find a go-to pair of summer pants, but I'm sorry to say I was rather disappointed with these. There is no XS option, so unless you're at least a size 6 these are going to be over-sized. I'm a 5'5" and a size 4, and the the small was quite loose. In fact they were loose enough on my waist that it caused the whole pant to sag and my knee armor sit further down on my leg than I would like. Now I worry about the knees pads shifting too much. I was also disappointed to find there was no seat reinforcement whatsoever. There is a bit of foam padding on the sides of the hips, but the seat itself is just thin fabric. If you've ever gone down and done a butt slide, you'd know why I wasn't happy to see this. Overall I still feel pretty vulnerable with these on. I guess my next step is to find a pair of protective motorcycle shorts to wear under these to make up for it. For those interested, I can't say they look flattering. That's not a big concern to me since I'm most concerned with practicality in gear, but they do make it look like I'm wearing my dad's pants. December 27, 2014
