Review on 🚰 Source Water Bottle Adapter Convertube - Convert Standard Bottles to Hydration Systems - Streamlined 3-Step Conversion - Convenient Hands-Free Drinking on the Go by Jason King

I've used it on a couple of hikes now, both with a full size backpack and a day pack. I have found it to be a practical alternative to internal hydration packs which can be problematic to access and refill. I would still use a hydration bag if I needed to carry more water due to water sources because they also sit better on my back. By using this you can avoid reaching for the bottle from the holder, which is impossible with some packages, let alone trying to return the bottle. It also makes it easier to stay hydrated because you can drink whenever you want and you don't have to stop to grab a pack to drink. bottles. **Note: Not all water bottle cap threads are the same. I was able to use a 1 liter Smart Water bottle (which is also compatible with the Sawer Mini water filter).
