Does what it says on the tin very good
Tried it during warm days in Spain, and noticed an immediate difference between 'normal' chalk and Maglock. Considering how little is needed for effect, I'd say this is pretty good value. Not needed for all sends, but when you do needed, you'll be happy to have a bottle!
Hey Elis, appreciate the solid review, and stoked to hear Maglock made a difference for you out in Spain! You nailed it, a little goes a long way with this one. Thanks for taking the time to share your thoughts.
Amazing product, I will buy it again 👌
Perfect primer specially if you suffer of sweaty hands! I apply a tiny bit in the beginning of the session and really dries my hands. Yes it is a bit pricey but last forever!!
Just a small amount of this and my hands no longer slip off slopers. Also love how little I need to apply so the 8g of maglock could probably last me months. Overall, a great product!
Felt better grip and chalk lasting longer after use more comfort on the slopers
Such a good product. I had friends in my gym to try it out and we all instantly felt the difference. It works as a primer and keeps hands dry and chalk locked in so you can send hard. I tested it on the hangboard doing one arm lock offs on BM2000 15 mm edge and after applying i held for a lot longer without slipping or dry firing! Very good :)
Best chalk primer out there
Maglock is incredible, nothing like anything I’ve tried before.
The moment you apply it, you immediately feel the difference in your grip.
Not for every session, but when it’s project time or comp day, this stuff is a game changer.
The perfect primer
I started using Maglock by Rúngne as a primer before applying chalk, and it has become a great ally for me. I don’t have particularly sweaty hands, but I’ve noticed that with this product the chalk sticks better and lasts longer, especially during repeated attempts on the same boulder or on routes with delicate moves.
The most noticeable effect is the greater sense of stability: the grip feels more consistent and the chalk doesn’t “disappear” as quickly as it sometimes does. I don’t consider it a replacement for regular chalk, but rather a complement: I apply it only at the start of a session or before trying key moves, when I want to maximize grip.
The 8 g pack is small and the price is above average, but since you only need a tiny amount, it lasts a long time. Overall, for anyone looking for more security and consistency in their grip, Maglock can truly make a difference.

I can really tell that this gives you a better grip.
And also because I have sweaty hands.
With maglock; I can climb even better...

Maglock won't be for everyone, but it does keep your hands dry for quite a while. Might not be super useful for boulderers that can dip their hands into a sea of Magdust on every attempt. But if you can't use chalk at all (maybe you're climbing on sandstone) or are projecting long hard routes with bad resting/chalking spots Maglock will come in quite handy.
Hey Pedro, thanks for the thoughtful review! You're absolutely right—for those tricky routes where chalking up isn’t an option, it really shines. We appreciate you sharing your perspective, and if you ever have more feedback, we’re all ears! Keep crushing it!

This is a brilliant product for keeping your hands dry
I used some at the start of a session and at the end (4.5 hour's later) my hands were still sweat free and dry
Use this then some magdust and you're onto a winning combination
Absolutely love this stuff, I’ve never dipped my fingers into a finer chalk. Truly when you use this, it will make you say wow, instantly improving your grip and confidence on those slick and grimy holds…
