A particularly useful accessory for hunters for the Gear Keeper universal roll-up holder. With its help, we can fix up to two whistles on our side, which will never disturb us when we are not in use. However, as soon as we want to use it, it's just one movement and you don't have to dig around in your pocket or bag. It is immediately rolled up when not in use, and there is no risk of loss.
This is the double loop version of a hoop, it also exists in two separate, simple versions.
