    Luxuriously plush.

    Kick back and relax with the cozy comfort of the Icebreaker Men's Shifter Pant. Merino wool lends a luxuriously-soft feel while pulling moisture off your body during fast-paced activity. It takes the form of a classic jogger pant, allowing you to wear them while running in cooler weather. A touch of added Lycra creates functional stretch when you're working out and running around the neighborhood. The elasticized waist features a drawstring tie for keeping the pant nice and secure, with elastic cuffs preventing it from snagging on your shoes. There's also a handy rear pocket for storing your phone, cash, and keys when you're out and about on the town.

    The Perfect Home Pant

    My search for the perfect house/lounge pant is finally over. I have been looking for years for a pant that was wool, comfy, but not to tight, not to baggy. The search is over. These are the perfect weight as well. Not to warm, or to thin. Nab a pair.

    Seriously impressed with these pants. SUPER comfy, I never want to take them off. If I wasn't already a true believer in Merino Wool I certainly am now! I wore these for 2 nights backpacking in the Wind River range in WY, including the 9 mile hike out with a 30lb pack on and there was ZERO smell after. Icebreaker killed it with these pants!

    Great quality and size info

    These are true to size and do not run large. I’m 5’10” 245 lean lbs and XL fit perfect . The pockets bow out a little , wish they would lay a little better. These are soft but not near an soft as wife’s ice breaker capris or my IB t shirts.
    All my ice breaker stuff looks new even after 2 years. Plus they breathe Awesome. Absolutely love backcountry, the best service out there. Got a deal on these

    Obsessed with these pants!

    I first saw these pants on a guy at the climbing gym. I knew right away they must be Icebreaker. I had to have them. I wore them not stop when I got them. Usually, wear them over my yoga shorts for when I head to the studio to teach. Or casually around town. But after I took them on a spontaneous backpacking trip, I became obsessed. I only brought them along because I didn't have any base-layers in my trunk. But they proved to be great for hanging at base camp in a morning hike.

    They do have a long rise and tend to run a little big. I may try the Small on my next pair when I order the grey.

    This are my husbands backpacking sleep/warm pants. We generally travel pretty light when backpacking and since he wears running shorts all day, these are a nice, soft, and warm treat for him at the end of a long day.
