Having been caught in inclement weather a few times in the last couple of years, I have learned to carry a stashable jacket. Typically, they are super lightweight nylon and are designed to wear over 1-2 thin layers max…and never over the top of a pack. Until now. This new Altra jacket is perfect for getting caught in the rain or the snow and needing that waterproof layer, while also having a cutout in the back for your pack! This open back is fastened with Velcro near the bottom, so slipping it off and on is a piece of cake.
The entire product weighs just 3.3 oz and stashes into this little pouch that you wear kind of like a fanny pack. I wear a hydration belt sometimes and it worked just fine with that but it is definitely designed to be worn with a hydration pack for long runs. In 2 of the 3 instances I had it on over the past couple weeks, I had to throw it on. From the moment of pulling it out of the pouch to completion was probably about 20 seconds and I even did it the second time while continuing to run!
