Osprey Women’s Dyna 6 hydration pack — like new/EUC S/M 86-102cm 6L and Loaded with features! Tons of spots to stash fuel, or other essentials. Front closer straps adjustable vertically. Fits a 1.5L hydration reservoir. (not included, but the 1.5L Osprey Hydraulics LT is selling on Osprey’s website for $21 currently). Designed for trail running but great for day hikes and biking too! This pack is like new - I loved this pack but with an injury I took some time off from running, got more into weight lifting, and now it’s too tight on my shoulders. My loss is your gain! Reasonable offers will be considered. This style is on eBay for $70-100.
