Part of our ultra-light series, the 500 ml is so light, you might forget you brought it. Weighing in at just over an ounce, its optimal hydration, no matter what kind of runner you are. Its pliable material conforms to most pockets, it shrinks as you drink to minimize water movement and it can be used with or without the tube. Topped with a new feature, the SpeedFill cap, makes aid station refills a breeze. Ultra light weight, ultra useful.

Great flasks
Awesome soft flasks. They fit in a lower pocket my arc teryx vest. Now I can carry just over 2 liters of water with ease.

Speed Cap is a fail.
I am not a fan of the "speed cap". It does not make loading any faster as it it difficult to open and close. Easier to just unscrew a cap on and off. It makes the opening more narrow and all around more difficult to use. Also sticks out in a way that it is very easy to rub up against you in a pack.

Works well
Fits well in my running vest and works as intended. Froze with some lemon water before first use and was able to get rid of the plastic taste!

Flip tops are an excellent upgrade!!!
I had the previous model of this (w/o the flip top) and was happy with it. Now, having the flip top is a game changer! Such an excellent upgrade. I recently did a 30K and ran with 2 of these in my vest. It was so convenient to flip open the top to refill versus having to unscrew and screw back on because sometimes it was hard to screw back on especially when you're trying to leave an AS. Love the new model!

Extra Hydration from an Awesome bottle
Love this bottle, the extra 100ml makes a difference and it fits fine in Salmon and Nathan vest. The oval shape makes it easier to grip when taking off the lid vs the round bottles. We have used this bottle on both 50K and 50 milers with no problems.

My favorite hiking gear
I love having the speedflask in my shoylder water pocket while hiking and backpacking. I use it for flavors and electrolytes and the bite valve means I drink more often. I do wish it came in a 1-liter option that fit in a backpacking shoulder pocket.

Best bite valve ever!
I am impressed with the UltraFlask Speed 500ml. It has the best self closing easy sipping bite valve! Also it truly is compatible with my "Be Free" water filter.
