Why We Like The Impulse Running Short

Some days just need that afternoon endorphin boost, so we pull on the Impulse Running Short to chase that high under the torrid summer sun. Icebreaker's cooling liner with naturally anti-odor wool keeps us fresh throughout our sweaty miles. We stride freely with the stretch and gusset submitting to our quest.

Fantastic in the Arizona summer heat. Very light and cool. Not sure how they will hold up long-term, time will tell.

Ice-breaker a deal breaker for extreme hiking

(This review was collected as part of a promotion.) I am about to attempt to walk the Camino de Santiago de Compostela this Fall in Northern Spain and need to travel light with only 2 changes of clothes, so the ice-breaker trunks I have are the perfect undergarment, durable, breathable and fast drying.

Works out well :-)

(This review was collected as part of a promotion.) I've switched to Icebreaker for all my one-carry-on travel - easily can go 2-12 days with just two pairs of everything. But I needed a workout shorts and shirt that don't need to be washed. This seems to be perfect. I suspect it might workout well in a pool too, but didn't try it. Fits true to size. Did not slip off.

Light weight soft running shorts.

[This review was collected as part of a promotion.] Soft flexible and loose shorts. Very comfortable. Runs a little big.

ICEBREAKER MEN'S COOL-LITE™ MERINO IMPULSE RUNNING

Excellent running short - comfortable and no pressure points. The photo on the website does not do it justice. It is not a pair of grandmas bloomers but an athletic style short..

Running shorts

These running shorts are beyond my expectations. As with most icebreaker gear they fit me just so darn well. In fact I just got off the treadmill and I am wearing them now. I love intelligent design and I love these. The gear pockets and the zip pocket-perfect. The feel next to my skin- lovely and dry. Can’t wait to wear them in the woods for running,but it is 2° and icy so I can wait for a few more days before I’m outside in these shorts.

Cool Lite Impulse Shorts

(This review was collected as part of a promotion.) Just slightly off in the sizing. Tight in the inner liner and loose in the waist. If I were to go a size up, the waist definitely wouldn't fit while the liner would. If I were to go down a size, the liner would be way to small but the waist would fit.

Excellent shorts. So comfortable

[This review was collected as part of a promotion.] I was a little skeptical on these shorts but that was misplaced skepticism. They fit true to size (I am an XL with 38” waist), and are so very comfortable. They will going on a long distance thru hike with me in the near future.
