As a pro ski instructor, having your hips tight and secure makes every turn and every move more relevant. At high speeds and sharp carves, your core needs to be strong and the Lock does that better than any other undergarment I’ve ever worn. The Active Cotton base layers were real positive surprise. They kept me warm and dry throughout the day. I never felt a chill or any itching like with merino or synthetics. Definitely worth trying for many reasons.
