During doing my Circuits at the Gym, I had to carry my water bottle around with me, the same when going in between machines at the gym. My sports sweat towel often fell off from around my neck. When I was searching Amazon for a bottle holder, this one was everything I needed. I bought one and tried it at my first Circuits class. I put my sweat towel through its elastic at the top, and my water bottle in the holder. I use an old leather belt to take the weight. The belt holder on the back of the pouch is fully Velcro which means that the holder will sit up high and not fall down so its hinge sits on my belt. Being a woman this means it will sit in a comfortable position on my front.
In summary, this has been one of the best things I have bought for my Gym. No more carrying my water bottle. No more sweat towel dropping on the floor. All in one place on my belt and no more forgetting them when I leave the room. A must for any gym user.
