    Standard 2L bladder but the high flow valve is super worth it. Had mine for over a year and no problems leaking or anything else. Definitely pair it up with the Mag-Clip.

    I bought this bladder as a replacement bladder after accidentally cutting my first one 🙁 and I love the pack and the bladder! There tend to be some issues with air in the tube (even after burping) but no leaks and I love the mouth valve.

    Valve is tight, no leaks. Easy to use while running and easily opens and closes. YOu do need to clean it once in awhile or funky yellow stuff starts to grow inside….recommend warm water and Lysol, soak overnight.

    Just recently bought the 2 liter hydration bladder bad, I have only ran with it twice once on a 40mile run and the 2nd time on a 12 mile run and both time it worked really well no issues with it. I’m still just getting used to using the pull out, push in mouth piece but really was impressed with it!
