    Soft Flask

    Seems to work well with the back. I figured out to blow air in the flask if you need to get it back into the hole so it’s no so limp. Then let the air out.

    600mL Soft Flask

    Love these soft flasks from Orange Mud. I have (2) 500mL, just purchased and used the 600mL. They work great in my Gear Pro Vest. I love all your products. Plus the customer service is awesome!

    I love the extended tubes for these flasks!!

    I previously had a different type of camelback and I didn’t like the short tubes for them. These make it super easy to sip and continue! Love these!!
