These things happen to the best of us. Each brand is different so follow the sizing guide on the site. It's important to be comfortable on the slopes so the best bet is to size up when you are ordering your kit. The hip and the waist are the most important to get right. Don't worry our gear insures that you can have both comfort, and style.
If you are not sure give us a call and our kit specialist will get you kitted out in the gear that makes your trip amazing. You can also try going to a local shop and trying on the brand before you order.
If you get your gear and it absolutely doesn't fit, call us immediately at 888-473-3111.
