Psychi | Ultimate Grip Rock Climbing Bouldering Chalk Ball | Grip Strengthener for Rock Climbing, Bouldering, Gymnastics, Weightlifting & more - Lasting Absorbent Sports Chalk For Your Gym Bag (x1)

Very good

This chalk has been great for climbing! The grip is solid, and it lasts a long time without needing constant reapplication. Feels reliable and does the job well. Definitely a good choice if you need something that lasts!

I have bought this chalk bag so I can boulder and it seems to work fine but I am required to squeeze it every single time I attempt a new boulder. I do not have sweaty hands but if you do you might even need to apply during the route as chalk wears out very quickly. Good value for £5 though.

Good chalk and lasts a long time!

I have recently moved from a CrossFit gym to a "normal" gym but still like to do CrossFit style work outs. Obviously the new gym doesn't have any chalk around so I got myself this and it works great. It can be quite messy so I carry it in a little bag and it's no problem. Great value for money

I use this when I play pool , GREAT

Nothing much to say other than it does it’s job very well. The chalk stays on your hands for more than enough time if you boulder.

This product is well priced and is of decent quality. However when I use it in the gym I do find myself topping up the amount I use rather often. Still a good product and is effective.
