Spotted over on the Shimano Lifestyle Gear website, this new Enduro Racepack is a new addition to their promising line of hydration bags (reviewed by Zach here).
This new model appears to be on the smaller side of the packs in the existing line up, with only enough room to carry the racing essentials. The straps above and below are likely intended to slog the full face and guards that are becoming mandatory equipement at many race venues, while the X-Harness should keep everything firmly (and comfortably) secured.
We’re still waiting for more details regarding the 4L pack, but stay tuned to the product page here for more info.
