Review on Vincita Bike Water Bottle Holder Insulated Stem Bag Handlebar Attachment Cup Holder Food Snack Storage For Mountain Bike, Bicycles & Bikes Pushchair by Tim Kallimanis

Handlebar bottle holders (aka stem bag) are incredibly useful for storing more than just water. I've used my fine for snacks, a camera and even an open cup or can holder for casual rides. It's convenient keeping items easily accessible and (with the drawstring closed) reasonably secure. Smaller riders, may have some issues with knee clearance, but that hasn't been issue for me.It attaches to the bike with a fixed velcro strap toward the bottom of one side, and includes two velcro straps that can be arranged on the webbing loops to attach to the handlebar and/or stem. I used the larger strap around my stem, but the small strap was too short to go around my 31.8mm diameter handlebars. The fixed strap isn't quite long enough to attach below the top tube on my bike's carbon frame, but I was able to secure to my steerer tube below the stem. (If my stem were low, the strap would likely be low enough for it fit through my frame). With just the two attachment points, it still rides very securely.The mesh pockets provide a nice bit of extra storage and the elastic securing them seems pretty durable. I'm not certain about how effective the insulation is, but the foil interior makes for easy cleaning.My first and favorite stem bag is by made Revelate Designs - while very similar to this in size and features, it's a bit lighter and high quality ,but it costs $30 more than this bag. This bag is 90% as good for 40% of the cost. The quality is fit for purpose and I wouldn't hesitate to use this bag for an extended bike packing trip. I really like stem bags and this one offers a high level of quality for its modest price.
