Fantastic!
"I cannot recommend this enough for walks/short hikes. I often hit a 7 mile train in town, and a backpack seems excessive, and I hate carrying my bottle by hand. This is comfortable, and solved nearly all my problems. My mini first aid attached with a carabiner, the little zipper slide secures my whistle and mini-tool. The mesh is perfect for my repellent, a protein bar, my phone, and I clip on my keys. It this slings around and out of the way. I loved it so much I bought 2 more for my siblings."
