Alpinestars Stella Oxygen Air Pants 3 5 1 1
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
