Pants like an A/C unit for your junk.

The only pair of pants you'd want to wear on a hot summer day. Ventilated, stretchy & ridiculously lightweight.

With a soft hand feel and no swoosh or shine in the fabric like you might expect from most light active pants. 

Thoughtfully designed with features that are essential for adventure travel. 

Stretchy waistband with an internal drawstring that can be tied outside or inside. Two small accessory loops for keys, sunglasses or whatever else.   

Side zipper pocket big enough for a large phone, hidden zipper on the back right pocket, button closure on the back left and traditional front pockets with an added media pocket on the right. 

All pockets have light, stretchy mesh lining that help keep everything breathable and dry super fast, making these pants perfect for when you need to hand wash and hang dry when traveling or camping. 

Aesthetically minimal, as packable as they come & most of all perfect for those hot a$$ days

I've bought stuff via Instagram ads and it hasn't worked out so great

I've bought stuff via Instagram ads and it hasn't worked out so great. This is not one of those times. I had a hiking trip coming up in the heat and wanted to try some cooler pants. I was able to walk through the forest staying fairly cool, no swishing and the color is nice also. I opted for a roomier fit but was worried it might be too big when I sized up. The drawstring came in handy for that and offered a good fit. While they are a little thin, I was worried that they might tear on a branch. I had no issue whatsoever. While it is a little spendy in comparison to the other stuff I use, but it works and with the lifetime guarantee and free fixes, I am happy I took the plunge.

Awesome, but

I really like the pants, but the elastic waist does not elastic enough. It is fine until you start being active. I recently hiked Mont Blanc and wore these on one of the days on the trail. They were awesome at first but before long they started to slip down. I guess I needed a size down. Great products but need a little more zip to the elastic in the waist.

Not much to complain about side from left side pocket being too large for a phone

Not much to complain about side from left side pocket being too large for a phone. The phone falls sideways and many people like myself prefer it as a phone pocket. Wish there were smaller inseam options but I guess I’m in the minority.

The most breathable pants I've ever hiked in!

The Vent Lightweight pants are the most breathable pants I've ever hiked in. Quiet and non abrasive with a soft waistband that feels good underneath a backpack. Around a one hour hang dry time after washing at camp.

Love these pants

Love these pants. Very lightweight and breathable. The medium slim fit is a bit too tight for prolonged physical activity but I'm gonna try a large straight leg.

Good for Hot Day + No Shorts

I am 5'5", 135 lbs. Generally speaking, I buy 30/30 jeans/pants. In this case, I bought size small and they fit well. Upon receiving them, I machine washed them and hung them. They dried the next morning.

The back pockets provide peace of mind. According to the video I watched on the Ketl page, there is one particular pocket in the front on the right side for a cell phone. However, when I put the phone in that pocket, the phone was exactly where my torso and my thigh pivoted, which created a weird sensation. Nowadays, everybody carries the phone everywhere, including hiking. I would probably like to have a pocket for my phone either on the back, on the side, or at a higher or lower position in the front, or even above the fly area.

On a very hot day, of course, they are a bit warmer than shorts, but they can reduce/prevent sunburn or bug bites. The breeze blows through the pants a little, which reduces the heating.

You’ll love these pants.

I purchased these pants because I tend to run hot but was tired of sticking out as an American when I travel because I was always wearing shorts and I wanted something presentable that would help me keep cool at restaurants in Europe where a/c is not as prevalent. These pants delivered in a big way. They don’t appear outwardly technical but they are very lightweight and I’m sure it’s in my head but when there is a breeze I think I feel cooler than I do with short. I love these pants so much I ended up buying more pairs for everyday life.

My Lightweight Vent pants were great for fishing too!

I was so happy with my Shenanigan Outdoor pants on my recent trip to hike in the Italian Dolomites that as soon as I got back, I wanted to order more. I chose the Lightweight Vent Pants because it has been so hit. Well, I decided to bring them on a fishing trip to the Northwest territories of Canada, and I am glad I did. The weather the first day was very warm with no real breeze and the pants were perfect! I know it was not a hike, but they were great for fishing too!

Seriously just buy it if you’re reading this.

Initially ordered the slim and they were too tight for me on my legs from my calves to my butt. Replaced them with the straight fit and voila, amazing. Customer service was easy and quick. The straight fit is super comfortable and it looks nice in multiple situations. It’s exactly like they described with thoughtful details and design.

Amazing for everyday

I love these pants, they are very comfortable and lightweight. The fabric breathes very well and the stretch component makes you forget that you are wearing them. They are a hair tight in the calf area, but not uncomfortable. Thoroughly recommended!

It fits well, is lightweight, and is highly breathable, making it very comfortable. If I had to add one thing, I wish it had belt loops.

BEST travel pants

BEST travel pants. I travel a lot to places that are hot and humid: I just finished visiting every country in Africa in November last year and was in Central America in March. These pants are perfect for hot and humid travel. Its the coolest I have stayed in this kind of weather. I love the pockets too; straight down and no risk of losing things. I have worn a lot of other travel pants but these are the best and they look good.
