The Alpinestars Raider V2 Drystar Textile Trousers-Black has the following specification Construction is top quality, they are very comfortable and very warm. Apart from the sizing, if I had to be critical of anything, it's that the internal liner doesn't fit over my boots, so while the outer shell will go over the top of the boot the liner rucks up inside the leg, which feels a tad weird, but it's hardly a deal breaker.
