The ONCRUX product is outstanding. I’ve been using their chalk for over a year and 1/2.I would highly recommend it.

I've tried a lot of different chalks, and most of them are really good. But On Crux is just the best. Has the best feel and consistency....it's powder like. It realy sticks to your hands and doesn't seem to come off as easily as other chalk. And it keeps your hands really dry. Which is very important to me since I sweat a lot. It's just the best.

The chalk just sticks to your hand. Great quality for the price you pay, just be sure to move the chalk into a bigger bag, otherwise it can get pretty messy when chalking up

Bought an ONCRUX Chalk Sock from the pro shop at our indoor rock climbing gym.Climbed a lot. Then needed a refill.Looked at a few brands and reviews on Amazon, decided to stick with ONCRUX brand powdered chalk.ONCRUX is good enough for our climbing gym to sell, so why not give it a try?Turned out to be a good decision.My son climbs 4-6 hours/week and he is happy with this chalk.In his words, this product is “Good. Chalk. Smashed up.”Comes in a sturdy resealable bag.I would recommend this product.

Its fine texture provides superb friction, giving me the confidence to tackle even the toughest routes. The chalk adheres well and keeps my hands dry without over-drying them. The resealable packaging is convenient and keeps the chalk fresh. ClimbCrisp is definitely my top choice for climbing chalk—it enhances my grip and performance every time I climb!

I just started bouldering and had a friend recommend this chalk. At first, I was skeptical spending $20+ for some chalk, but this chalk is well worth the price. It’s super fine and sticks to your hands like no other.

Where do I even begin? I love on crux as a brand for so many reasons and the powder chalk is one of my favorite products. I had tried other powder chalks before but even found some fine or super fine ones to still feel kind of granulated but this feels like a straight up puffy cloud in my chalk bag, it is SO soft to the touch. I feel so confident in my grip when I use it. It also lasts so long so it is definitely cost efficient. The customer service is amazing as well so that’s a huge plus! You can’t go wrong with On Crux. I’m a huge fan and have only used on crux since I first tried them :)

While in Boston, a friend of mine from Asian climbing collective gave me this chalk to use during our climbing session, and I absolutely loved it! I have sweaty hands, and can confirm that I had no issues with grip while climbing. Ordered myself a bag and will continue to use it in the future.
