I bought these for skiing and I'm so happy I did!. I bought these for skiing and my brother bought the Adult Snow pants and so I had to get something smaller. the size I got was XL and my inseam is about 28-29 and they are a great fit! Even with my ski boot! By far they are the nicest pants Iv'e had. the zip pockets a great because the keep every thing in. I ski freestyle and they meet the requirements that you would need like, flexibility and mobility they allow for good movement for your legs. They Keep the snow out and are warm, I use my base-layer because I over heat because they are so warm. The stitching is good, I have taking some hard hits with them and the stitching did not come apart which made me super happy because I thought for sure they would tear apart with all the weight and sometimes drag from the slide.Lets compare with the Adult Arctix snow pants and the Kids snow pantsI found that the little key ring by the belt loop (don't know if it is called that) on the adult pants are plastic and the ones on the kids are metal. When plastic gets cold at a certain degree it gets brittle and breaks, where as metal does not.The Inside of the kids pants are lined and the adults pants are not. This is good because they will keep more heat in where as the adult pants you might have to wear more, depending on how cold it is, how much wind there is and the wind chill. The only problem with having it lined is when your wearing jeans or something and its harder to get them on.Pockets are about the same but a little different size pouches. Like you have one cargo big pocket that is zip and then you have little that is Velcro. I think on the kid pants you have to two smaller ones instead one big one on the outside.There is also two waist buttons on the Adult pants and only one on the kid pants. I really don't see a difference, I use a belt with my pants so I didnt notice a difference at all.I would recommend these to anyone who wants good snow pants that are durable. They work great for me and I love them and I will buy them again.Hope thise helps you decide if these are the snow pants for you!
