    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!!

    EXACTLY WHAT I NEEDED

    MY PURCHASE OF THE ULTRAFLASK 600ml SOFT FLASK, 20oz HAS BEEN NOTHING BUT OUTSTANDING! IN COMBINATION WITH MY ADVENTURE PACK, THEY MAKE SUCH A GREAT DUO. THE 600ml ULTRA FLASK IS JUST THE RIGHT AMOUNT OF FLUID THAT I NEED WITHOUT ADDING TOO MUCH WEIGHT TO MY PACK. ALSO, IN MY PACK IT IS IN THE PERFECT POSITION FOR ME TO SIP WHILE IM RUNNING OR WALKING ON THE TRAIL. I HIGHLY RECOMMEND THIS PRODUCT FROM ORANGE MUD.

    Convenient and functional

    Adding two 600 ml flasks to the 2-liter vest gives me over 3 liters of hydration. Perfect for a long run!
