Why We Built It

It wicks moisture and dries incredibly fast, making it a go-to for backpacking, wet-wading the local waters, or squeezing in a quick back nine.

Durable, Wearable
Review by Aaron

I've almost been living in these pants, at least when in the backcontry. I'm just really pleased with how they've performed through every kind of condition the summer has had. In the humidity of the Hoosier National Forest they were light and breathable. In the wet and windy Pictured Rocks coastline, they dried quickly and even rinsed the mud off without much effort at all.

They look great and allow for mobility in everything I've put them through, which is a ton of hiking, bike rides and a few street festivals in between.

Really couldn't be happier. Oh, and they're the most comfortable pants I own, kinda feels like being in my sleeping bag.

Excellent Summer weight pants !!!
Review by Chas

I simply love these pants. I have never owned a pair of totally polyester summer weight pants. These pants are cool, well designed with a slim stylish fit, break the wind when necessary, lightly water resistant, resist wrinkles, pack extremely well, light weight, and Stio's color gray and tan are excellent as well. I have worn them to keep the mosquitos off my legs for an evening concert while not wanting to be too hot - and they did both very well. I have also worn them as a wind resistant layer which also has an indirect way of keeping my legs warm. The wrinkle resistance is great and they will be my new go to pant while traveling during the Summer early Fall seasons everywhere. They are suitable for informal functions as well as dressy enough for most any evening out. Due to their very thin lightweight material, I would not recommend them for working in the yard etc but as a travel pant I do not think they can be beat. I would highly recommend them.

The best that I have found!
Review by Matt

Awesome! They work well in a climbing harness, great on the bike and quick dry like no other. A bit slim and short but very functional and better than all of the other brands that i have used (I'm 6',215lbs).

Just received. Fit is good, material is nice. So far Stio is batting 1000%
Review by GingermanRVA

These pants are very nice and the fit is good. I am 5-9, 175 and ordered the 33. Stio stuff generally fits me well and this is true for these pants as well. The material is smooth and thin with a little bit of stretch. It might be a little too thin for sub-50s so I will likely see more use for these in about 6 months. In terms of look these are much better than many other soft shell, poly pants that i have bought in the past. I would wear these out and about where many non-cotton of this brand and others have too much of an athletic look. Good stuff all around.

Too small
Review by Todd

I love Stio and have several pairs of pants but this style was too tight.

Love these pants
Review by Jake

I don't write reviews but am willing to do it for these pants. These are my go-to summer work pants for the office. I fly a lot and these are the perfect pair of traveling pants because they're light and easy to wear and you look good.

Review by Andrew

I was looking for a light khaki to wear to the office, but did not want a thick, work style fabric. The Keeline nails it, so comfortable, these have become my every day pant at work, out to dinner, hanging around the house...guess I need another pair!
