I love this belt system! I love how it fits me (kinda round and lumpy) and I love the bungee. It’s not stiff at all, Baxter had more than enough lead to sniff around while we’re hiking and running. I love the water bottle holder. It’s easy to access and is very secure. Good pockets. And the quick release part of the belt is incredibly secure. Baxter is only 25 pound but when he sees a squirrel and decides to go for it, you’d think he was twice that size! I feel totally satisfied that he won’t break free. To note: zip pocket is a wee bit too small for all the usual stuff I take: phone, keys, collapsing bowls and my inhaler. But I can pare stuff down and make it work, and keep his treats in the other pocket. We’ll probably be using this more frequently than the other trailer waist belt (the one without a water bottle) because it’s got everything we need for adventures that don’t take the whole day.
