What is 686's Hydrastash® Technology?

If you looked up the word Hydrastash® in the dictionary it would say something like: “A way to stash your hydration inside your winter apparel.”

But you won’t find it in the dictionary. Why? Because we invented it! It can be further explained as an innovative hydration system built into the garment that provides on demand access to water while on the mountain. That’s right: ride more, rest less, and stay hydrated without leaving slopes.

Let’s get a bit more technical. Hydrastash® is an exclusive, patented hydration system discreetly hidden inside your garment. It is simple to use, sustainable, and safe. On demand access to water is provided even when you’re on the lift or in the backcountry without having to carry a bulky water bottle. The system is strategically designed around your center of balance when full and once empty it is nearly weightless. Our pro team gives it their full trust as it is designed to bend upon impact—not break. Hydrastash® is also a part of the solution to decrease the single use waste in the form of water cups at ski resorts.


In order to create the ultimate experience we designed the slimmest bite valve currently available on the market today. Our patented Microbite™ Valve is self sealing when stressed with internal pressure and has a comparable flow rate to standard bite valves twice its size. It’s connected to lightweight and highly flexible tubing that allows your jacket to move as freely as you. Its length can be easily customized to the user and cleaning is a breeze with a Hydrastash® cleaning kit.


A full zip stretch channel runs from the Hydrastash® bladder pocket to the Microbite™ valve for easy access. Insulation on the exterior of the channel and breathable inner material effectively traps your body heat in the channel and provides extra protection against freezing.


The patent pending design securely holds the bladder in a newly designed powder skirt system. A stretch connection band increases mobility and our new patent pending 3x2 Multiple Closure System provides more closure options than ever before for different body types. The entire Hydrastash® feature is engineered to fit tightly around your center of gravity, providing unmatched balance and reducing any swinging effect of the fluid weight.


The custom designed anti-microbial slim bladder is taste free, holds hot or cold fluids and is designed to fit around your waist for optimum balance. Anti-slosh dams are engineered throughout to prevent motion when fluid is low and the entire bladder is guaranteed not to break under stress. It features an easy fill waterproof rolltop opening that has been tested to become the ideal solution of filling and cleaning your bladder. You can remove your bladder fully or just partially from your jacket to fill. It's so strong we've even run it over with a car and it didn't open.
