WOTOW Bike Handlebar Bottle Bag, Bicycle Insulated Stem Drink Cup Holder Water Bottle Bag Cycling Frame Strap-On Waterproof Storage Pouch with Shoulder Strap for All Bikes Daily Use Touring Commuting

A little smaller than expected, but will do the job

I bought this bag as part of a bundle with the same brand handlebar cooler/bag, so I only paid less than an extra $4 for the cup holder bag. What a bargain at that price! I think it is a good deal at full price. It was easy to attach to my bike, and holds my phone securely. It will hold a 16.9 oz water bottle as well. Since I already have a water bottle cage, I will probably use it to hold wallet, keys, small tools, and maybe a snack. It has a drawstring to keep the items inside. Perfect! Also, it has several velcro straps and I am sure this could be attached to a backpack, belt, or what-have-you. So it useful more than just on a bike.

Bought this for bikepacking and long rides. Fits a drink bottle if needed, but I mainly use it to carry food which is easy to access while riding. Has handy pockets in the side and multiple locations for straps. Quality is good.

Good quality, easy to securely attach. As others have noted, it is quite small, so not suited for all drink bottles, but perfectly adequate for snacks and smaller drink bottles

I’m happy with this bottle holder. It attaches securely and holds a smaller water bottle well. So many water bottles are now very tall, and wide, and that style would not fit but a “standard” 16 oz fits well. It’s a little tight when I also put my phone in the pocket, but often my phone is stashed elsewhere.
