With an integrated, refillable chalk ball, a brush holder and a slot for your lead certification tag, this bag is tailor-made for indoor sessions and can clip directly to your harness or you can opt to use the included chalk bag belt.

• Brush holder
It does the job right, but I see no reason to splurge more money on this brand compered to other cheaper small chalk bags.
It does not perform better then my old cheap chalk bag, it stains with chalk (even tough it's supposed to be chalk repellent), the closing string is not especially good, so sometimes it's hard to reach for more chalk with one hand while climbing.
All in all a good product, but it can be better.
The bag is made of a soft material which bends the bottom of the bag upward when falling, therefore cutting off the chalk area from the opening.
Nice brush holder can fit most wooden brushes with a thicker handle.
The only downside is that its too soft to stand upright on its own.
Best chalk bag overall.
