Quiet

The flask are easy to fill and clean. Once the flask is filled, let all the air out of the flask and you will eliminate any noise from the liquid moving.

All around a Great products

This year I decided to run the Grand Canyon from the South Rim to the North Rim and then back to South Rim "Rim2Rim2Rim" which was roughly a 48-mile run and I know I was going to need the better of the better products for this run. So after doing a lot of research on Running Hydration Packs I came Orange Mud. I had made the purchase of the Endurance Pack V2.0 and two additional 20oz/600ml soft flasks for this journey and so happy how the products were AMAZING! Very well Build and fit like a glove and had No problems with any of Orange Mud products. All my friends I ran with were asking where I got my Running Hydration Pack. Orange Mud products a Definite MUST!!!

Soft Flask Extra Water

During P2P 100 I carried this extra soft flask in the accessory bag empty until I needed it. When the temps got warm, I filled it up and kept it in a front pouch. I initially got the double barrel pack because I do not like water bottles in the front. This flask sat comfortably in the front pouch and did not bother me at all. Typically the two bottles in the back are plenty of water, but this was exactly the extra bit of water I needed to get me through a couple of the longer sections during the heat of the day.

Great companion for the 1L hydration pack

Fits securely in the front pocket of the 1L hydration pack. I like to have an electrolyte drink in the bladder and the flask for water. Cleans up easily.
