In some cultures, the number "7" is considered auspicious. In trail running culture, the number "6" is considered spot on, well, when attached to the volume a pack can carry. Dynafit has hit that sweet spot with their Sky 6 running pack. Ultra-races are no joke, especially when the space between aid stations is large and your pace may have slackened a touch. It's nice knowing you have all the gels, bars, blocks, liquids, and clothes you'll need to get to that next oasis. When the legs really start to give out, you'll be glad you brought some poles along that have been quietly riding along on the back of your pack the whole time. If it's the kind of day where you stash your jacket and start to sweat your keister off, the Elastic Airmesh material will be a welcomed part of staying cool. Around here, "light is right" is thrown around quite a bit. So is, "fit first!" This pack will conform to your frame and allow you to breathe with an elastic chest strap system that is secure, but not restrictive. Space to spare, features to fawn over, fit that feels cozy - take your pick of the best reason why Dynafit's Sky 6 running pack should become a part of your running world.
