Awesome Jeans

Watch out, these jeans are so f*cking awesome, they will ruin you from wanting to wear anything else. I have 4 pairs of them, and I hate skinny jeans too, but these made me a believer. I just wish they offered them in normal cuts too, cause I use them for everything. I'm talking about cycling, yoga, working, going out, and bouldering. The seat wears out after awhile cause I ride daily in them on the bicycle, but otherwise they are like heaven. Even the pockets are stretchy so I don¨t even feel my iPhone in the pockets and can climb like as if I wasnt wearing them. My girlfriend looked at me when we took some Yoga classes with her cause nobody in their right mind wears jeans, but I was like you don't know. Now she owns a pair herself. Also, I had a problem with the leg seam of a black pair and SoIll replaced them without any issues or fuss, so I cut the old pair into shorts and have them as well. Top product, top service, top customer support. Buy these but I warned you.

Black denim

Great pair of jeans, flexible, comfortable and very nice. Also have had blue for over a year and they were the only jeans I wore till I bought these.

The most comfortable jeans I own!

These are my second pair of So Ill jeans and I already know I’ll purchase a third at some point. I appreciate the stretch and the variety of activities that these pants accommodate.

Andrew Gordon

These are a great fitting pair of jeans that not only work really well wearing to the office but also the climbing gym. They are extremely comfortable, stretchy, and I have no problem bouldering AND/OR drinking beers afterwards in them!


I’ve been rocking these for a few weeks now, and I couldn’t be more pleased. They’re well built, stretchy as heck, and look good enough that I wear them to work instead of having to change out at the gym. They’ve held up to my lifestyle, and my Gumby quality climbing fantastically. Sure they’re spendy, but you really do get what you pay for.
