Review on 🚰 TRIWONDER BPA-Free TPU Soft Folding Water Flask - Collapsible Hydration Pack for Running, Hiking, Cycling, Climbing by Ricardo Tlaxcalteca

I have had these Salomon bottles for years and bought them as a spare. They work like a bite valve and appear to be very durable. However, this brand (Aonijie) has some design flaws that result in the flow rate being much slower than half the Salomon bottles. When running, you don't want to use your large lung capacity to pull water out of a bottle. . If this is your use case, I recommend passing it on and finding another. If you're on the go and don't need water efficiently, these bottles might do the trick. In case the Aonijie designers are reading this, here are the details on how to increase the flow rate to be similar to Salomon's: - Attached is a picture of the Salomon cap. left and your right. The designs are very similar at a basic level. The first improvement concerns the upper part. The cylindrical section at the top of Salomon is shorter than yours. This difference lets more water through when you use the bite valve. The second improvement concerns the middle part. They used a thicker, stiffer material than Salomon for this product. When biting, the opening around the wide part of the top is larger for more flexible material (Salomon). Assuming this doesn't infringe any design patents, these two improvements will make the flow rate usable for runners.
