Harbinger Refillable Chalk Balls, Comes Full, Produces Less Dust Than Loose Chalk, Greatly Improves Grip For Weightlifting, Doing Gymnastics, Rope Climbing, and CrossFit

The chalk inside is a solid ball. Had to smash it against the floor for 5 minutes before it's usable. After I got the chalk loose, the sock worked as expected. It lets just enough chalk out so that my hands can be coated while not leaving a mess everywhere.

Great chalk for heavy lifts, last a pretty long time even with daily use. Grips amazing on bars.

I like them. But they are not as good as the powder form. Less messy but less grab as well. I use them for deadlifts and have to use every time.

We purchased these to use at my daughter's cheer gym. They don't have air conditioning in their Florida gym so it is very hot and humid. When stunting, the bases were having a problem holding onto the girls as everyone was sweating. I purchased these in hopes of having something small and subtle for them to use before stunting. They are the perfect hand size and produce enough chalk without making a mess like a traditional chalk bowl. It is also easy to refill.

These are great to put in your gym bag when traveling (well, put them in a ziploc and then in your gym bag). I actually left one in my bag and one at the office gym. I work out at home, but when I'm traveling or miss my morning workout and have to use the office gym, I have one there.

Does the job

Its chalk in a sock. I've bought theses a few times and they work great. These chalk balls keep the mess to a minimum and the chalk is good qualtiy. I wouldn't try to refill them though. The socks don't open up that much and its hard to get anything into them.

Keep these puppies hanging on the squat racks at my fitness studio. So easy, so convenient, and much less mess than chalk bowls and other chalk balls!

I'm new to working out and needed chalk to help with my grip when using my kettlebells. I did not expect to pouches to be of such high quality. Would highly recommend

Good chalk distribution; although not any cleaner

Just what the doctor ordered.

Super práctico Excelente calidad

Mi hijo escala deportivamente y perdió su bolsa de tiza y decidimos comprar otra y estas bolas de gis para reemplazarla. Las bolsitas estan muy buenas pues cierran bien y no se aflojan por el seguro que usan, y el gis por lo que me comenta para hacer esta reseña es que le gusto bastante. El único comentario que me hizo fue que el gis venia tan pero tan duro que tuvo que sacarlo de la bolsa y reventarlo con un martillo un par de veces para poder ya aflojarlo con las manos. El hecho de que vienen 2, y valen lo que valen hacen de estas bolas de gis una buena compra.
