Many appreciate how it converts bottles into hydration bladders for hiking and enables seamless compatibility with popular water filters like Sawyer Squeeze. Common feedback highlights the versatility and lightweight design for backcountry use.

    It's ok

    It works and does what its supposed to. I just wanted an adapter cap for the smaller threads. Wish they made a simple one piece system without moving parts. Really like Hydrapak bottles but I could do without this system. I'll probably break it at some point.

    Great Solution to a common problem

    This cap is such a great way to handle water without spiling half of it while you filter. Literally plug & squeeze with my Mini Sawyer.

    If you want a half bottle/half bladder, get this

    This is a great lid to use with a drink tube. Just invert the water bottle and you've got a bladder. Great for hiking. I also like how it seals itself off nicely when the tube isn't inserted.

    Works perfectly

    Purchased this adapter to connect a 2 L Hydrapak Seeker (42 mm) to a popular water filter (28 mm). I use the 28 mm threaded adapter so it can all connect and filter water directly from the Seeker.
