David Z.wrote a review of Osprey Packs Savu 4L Pack on May 31, 2019
Familiarity: I've used it several times
This pack is the perfect size for my intentions and well-built. However, my purpose is to use it while mountain biking, meaning removing and inserting water bottles while riding. Unfortunately, the bottle holders collapse when not in use too easily, meaning I cannot insert the bottle again without moving the pack from my backside to frontside and then using two hands to hold the carrier open while inserting the bottle. So, just doesn't serve my purpose at all. The more "stuff" you have in the baggage compartments the harder it is to insert a bottle in its carrier.
