Review on AONOJIE Sports Collapsible Bottle Replacement Outdoor Recreation by Dustin Woodrow

I have a maximum directional vest that I use for ultra marathons. I was frustrated that I couldn't buy the straws separately and had to buy two new bottles with straws because the bottles that came with the vest were just caps. The straw's mouthpiece broke recently, and I didn't want to waste $44 bottles on new bottles and straws (those bottles are $22 each). So I stumbled upon these which were almost half the price and sell replacement straws separately. Haven't run in them yet but tested them in a UD vest and they fit great (500ml). Also, the straws are slightly insulated, which is nice because I'm running in the snow. Straws can be rotated 360 degrees and have an extra valve that squeezes the straws. If you squeeze the bottle well, nothing will come out even with the valve open.
