welcome to So iLL...
We started shaping holds in a Southern Illinois barn over two decades ago. The space has changed since then—now we’re in St. Louis, all 10 of us under one roof—but the heart of this place hasn’t. We’re still family-owned, self-financed, and hands-on with everything: design, photography, marketing, operations, logistics, packing…all happening just a few feet from each other.
Your support is what keeps this work moving. Thank you for for being part of what we're building.

This was my first purchase from So iLL and we're really impressed by the quality and packaging. The colour is true to the website and the finish is excellent for climbing. Comes with all of the screws neatly packaged inside. Very tidy. Shipping and service were smooth and they shipped it to South East Asia where I'm located. I will CERTAINLY be back for more.
ich habe den Hoodie in S gekauft, normalerweise würde ich M nehmen. der Hoodie gefällt mir sehr gut, ist aber wirklich sehr gross ausgefallen. er ist sehr bequem und kuschelig warm. das nächste Mal probiere ich eine Nummer kleiner. auf jeden Fall ist er zu empfehlen.
Great deal nice for holiday gift formclimber
I think these are my 12th pair, just waiting for them to restock so I can get more
These are my first climbing shoes that I’ve purchased. Used rentals until now. I used the advice to buy small and indeed they were difficult to appreciate until I got on the wall. The shoes found their home on a very small ledge that impressed upon me the difference between on-the-ground comfort and learning the craft of climbing. I have a lot to learn. The build quality seems very high so as long as I keep trying it seems like these shoes will keep ahead of my pace for a long time.
Love the bag. It fits everything. It’s pretty tough and holding up in Seattle weather. Really comfy. It feels deep but allows for width if needed. The inside pocket would fit a laptop and has an outside zip to fit chargers etc. this bag will fit a ton.
My second hoody. My gf kept stealing mine because it’s so comfortable I bought her one.
These are the most comfortable and versatile shoes that I’ve ever had. The quality is on point as well. Thank you so much Jason and the So Ill crew for all you do! I will definitely be telling my friends and family about them.
I got the black one for myself. Love it!😊
Bought it as a gift. He’s gonna love it!
Conceptually, putting this hold on a keychain is hilarious. Very well made and perfect companion for any set of keys
Really love this shoe. The color is great, shoe itself is soft. Would definitely buy again and recommend it to others.
Purchased for my teenage grandson. Matches shoes and ski cap i previously purchased. He was extremely happy
Always fantastic products from the So Ill team! My kiddos will absolutely love the 2 charms we got them for gifts!
Very satisfied with what I got. Great variety of holds and families, even got a super size pipe hold! Will definitely buy another box when it’s available.
