I've been using this bag/clip for about 6-9 months now.

1. The position of the bag is more comfortable than the a separate chalk bag. It sits higher and doesn't have an additional strap going around your waist.
2. At the time I accidentally ordered an additional harness attachment but this turned out to be quite handy - I ocassionally climb with a younger child and instead of having a separate chalk bag for them, or adjusting my own chalk bag strap to fit them every time they climb, I can easily transfer this chalk bag to their harness.
3. I was worried about using this outdoors as I wasn't sure how secure it would be but I've been fine. It will collect some dirt on the magnetic part of the clip but this is easily wiped off.
4. The brush placement works well and I can take it out and place it back on the bag without needing to take the bag off the harness.

product works well and they have really good service! I recommend this product.

This chalk bag is premium quality. The magnetic attachment is very strong, never worry about it falling off. So much better than a carabiner and doesn’t hang/sway while climbing. Definitely recommend!
