Designed to run a little farther.  Slightly roomier than the SUB45.  A clever hydration system, a low profile soft flask integrated into a thermo-pocket to keep liquids cooler longer, the SUB90 is ideal to carry your phone, keys, cards, and hydrate when going for a longer run, hike, bike adventure.
