Review (3/5): Decent brush, but quality of the bristles is lacking
I've been climbing for around 15 years, so have gone through a number of brushes of all shapes and sizes. Experience shows that boar's hair works best for removing chalk, dirt, etc. from holds, both rock and composite/plastic holds in the gym. This brush is very nicely constructed - strong, thick handle and head. However, the actual bristles are much lower quality than what I've found in other brushes, to the point where I even question whether they are truly boar's hair or just some artificial/imitation material. I say that because the tips of the bristles are "smooth" in comparison with the "grippy" feeling of good-quality boar's hair. Overall, a fine brush, but I'll probably look to a more known company like So iLL, Metolius, Black Diamond, etc. for brushes when it's time to replace.
