Common feedback highlights the versatility and lightweight design for backcountry use.

    Screws on easier than previous models

    I like that this cap isn't as finnicky to screw on as my older version (purchased in 2020). You have to do a dance with the old once, but since it actually spins, it's not as much of a headache to put on the bladder. I appreciate that it clicks and holds tight. However, if you have issues with your grip strength at all, the release of the hydration hose might get complicated as you have to lift and turn to release.

    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.
