Imagine being out on a long run or ride, or being in the gym. Rather than settle for water or buy a sugary drink from a store, you just fill up your water bottle and drop in a couple of nuun tabs. By the time you’ve tied your laces or put on your pack, you’ve got a complex electrolyte drink that recharges your salts, is refreshing and more efficiently absorbed than water alone or most sports drinks on the market.

Outdoor Research

At Outdoor Research, we think that life gets better the minute we step out the door on a new adventure, no matter how big or small. We learn about ourselves, each other and the environment every time we get out. We see the world more clearly, and that compels us to treat it better. More than anything, we’re convinced that if we inspire more people to get outside, the world will be a better place. One of Seattle’s best kept secrets, the Outdoor Research Retail Store not only offers a full range of goods to accommodate our core sport enthusiasts and novices alike, it is also the only place to view our apparel, glove, and hat lines in their entirety.
