Convenient, lightweight, no sloshing - Platypus SoftBottle With Push-Pull Cap

Needed for trail running with front and lumbar packs. Got two half liter bottles, one capped, the other with hyperflow cap. The hyperflow cap had a minor leak around the twist on portion, adjusting didn't seem to remedy the situation, thus nixed one star. Placed full bottles in Ribz front pack with hyperflow cap extended outside the zipper of one pack to prevent unintended discharge. When empty, the bottles rolled up and required little volume in pack. Very light weight yet durable. Sloshing can be annoying when running, and rigid bottles slosh as fluid is progressively evacuated. Compressibility of these soft bottles eliminates sloshing as walls collapse with evacuation.
