Smartwool  Active Run Pants - Men's

I'm generally not a pants or tights wearer when running unless it's super cold, which is rare in the South. However, I picked these up for a difficult100M ultra race because I knew they would be necessary for being out in the cold that long in the dark. These pants did not disappoint. My lower body was never cold in the 20-degree weather. These pants have just the right amount of flex and don't hinder your gait. I'm not a fan of pockets and loops because I wear a vest, but the pockets on these pants weren't obtrusive. I wish they were a bit longer, but this is one set of jogger length pants that actually fit over my large calves. I was not able to put them on at an aid station over my Altra Olympus shoes though. Overall, very comfortable with no chafing during a long stretch of wear.

I appreciate Smartwool's line of products. They give real attention to detail and quality. What I didn't realize about these pants (size large) is that they are more of a 3/4 length pant - I'm 6' 1" and the bottom of the pants hit me a couple of inches below mid-calf, so quite a bit shorter than I expected. Other than that, and I can live fine with them being on the short side, they are good quality running pants. Maybe they are intentionally short-legged since they are designed for running.

The material on these running pants are high-quality. They’re also very light and out of the way when you’re running I haven’t noticed any chafing. I’m going to buy me another one.

Comfy! Warm! Worked well for long outdoor runs in colorado winter before the Sun came up.

I've mainly been using these over leggings, as a shell in winter. they help keep out the cold & wind, and for me are a good middle-ground between skin-tight and baggy/sweatpants. Good fit; as others have mentioned elsewhere, the legs of these pants won't necessarily go down to your shoes but they work well for me at 5'9' in medium - I'm not showing too much sock. The hip zipper pocket is big enough for an ID, small wallet or keys - not for a phone. Drop-in side pockets are good for whatever but don't zip. The inside of these includes seams which take some getting used to against bare legs. I wish they came in something other than black, but these are understated while being obviously designed for sport. I appreciate that Smartwool doesn't plaster big logos all over their stuff.

By far my favorite pants to run in. Surprisingly warm for how thin and light they are. I feel zero resistance when running in them.

Bought for fall/winter runs. They are lightweight and breathable - so would need layers under if it was colder than -10 C. Bought size large due to big thighs, waist 33. Decent length, quality made, nice pockets. Would consider buying more.

This product was supposed to be a great pair of running pants that was supposed to last more than the first wash. This really stinks, compared to other brands that have a better price and better quality.

This active pant appears thin, but it performs effectively down to around 32°F. It offers no resistance while running, is incredibly lightweight, yet keeps you warm!

I run in these below 45° and they are the bomb. They are warm, they stay dry… NO PILLING!! Love them. Highly recommended. Down to -15!
