Sawyer Products SP115 Fast Fill Adapters for Hydration Packs Blue/White ,One Size

Used this as an off-market conversion kit for the Hydrapak Stow water bottles. I'd been wanting a way to use the smaller flexible water bottles as a mini hydration kit for quite a while. I just need a top that could screw on that let me connect a quickconnect tube. I'd even contacted their customer service to ask about the possibility of them creating something or how to create my own version with their accessory products. Then I found the Sawer kit. Since it comes in pieces, I put the female receiver on the short supplied tube and the screw cap. I took a correctly sized tube and cut it so I had a shorter and longer version. Only had to use one of the male connectors this way. May make a really short version with the extra connector. It works fantastic! Exactly what I was wanting and can be used on my 250ml, 500ml, and 1L Stow bottles perfectly! Will probably work on any 23mm compatible flexible bottle too.

I love this adapter for my set up, I have a bag with a lumbar water bladder that is easily accessible so I didn't need to splice the actual hose. This makes filtering water on long hikes super easy.

Work well

Pretty easy to install, although it was fairly loose when installed on my Ozark Trail hydration bladder line. I wrapped a bit of Teflon tape around the barbs which seemed to fix the problem.

Fast delivery & as described. Part of water filtration

We almost didn't get these for our Pacific Crest Trail section hike. We planned to use some really good water bottles my daughter bought us, but realized how inconvenient it was to get to those in the side pockets of our packs.It was simple to cut the line, insert this, and then switch out the bite valve on our camelbaks for the adapter. Just hold the tube up so any water in your pack doesn't get all over! I only made that mistake once!eWe refilled our pack bladders several times over the course of nearly a week of natural-water collecting, and the connector worked great every time. We'll keep these for a long time!I'm so glad we did this since it meant that we didn't need to take our bladders out of our packs, fill them (getting them wet), and them try to get them BACK into our packs with all the other stuff in there! We used water bottles when we had to, but this made a big difference!Would I buy one again? If these things wear out, I'll definitely buy more!

This product is a game changer instead of having to empty your backpack to fill your bladder this hooks right up in a flash

This is the exact same connection as the HydroPak Quick Disconnect. Even better is that you get 2 for the price of one from HydroPak. No leaks and no mods required. Just plug it into a 1/4" tube end and you can quickly convert any of the Sawyers into a QD for the HydroPak. Learned on youtube from a guy called PreparedAirman that you can QD two HydroPaks and a Sawyer in the middle for a quick and easy Gravity filter.
