          Hands Free Hiking

          Bought 3 of these for Christmas hikers. They all put them on and will not take them off! They wear them to hike, school, shop, walk around town. The reflective strip really stands out from far away for safety. Very nice gift.

          Useful for my walks

          Perfect for my needs. I used it when I go for walks. Bulky for air travel. Uncomfortable if I sit for long periods.

          Fits my 9year old

          Needed to grab a smaller waterbottle from tjmax but otherwise was perfect for our disney trip for kids to carry own snacks and water!

          The size and comfort of this bag are great . However , this bag isn’t waterproof.

          Thank you for your feedback! We're glad to hear you like the size and comfort of the bag. 😊This bag is designed to be water-repellent, meaning it can handle light splashes and everyday moisture. However, it is not fully waterproof, so it shouldn’t be submerged in water or exposed to heavy rain. We appreciate your understanding and your support!

          Perfect waste pack for short heights and carrying basic cycling supplies

          This is just what I was looking for, a well-made pack that's not too big that I can carry stuff when I go on a short hike, or run or even on bike rides to carry some basic supplies as I hate having a tool bag. Just the right size and very happy with the quality
