*listed under “orange mud” and “Salomon” to increase visibility since Orange Mud is a smaller startup* EUC only used once on a test run before deciding I am not a bladder person. I have used their bottle based packs for years for marathons to 100-milers and love them! Amazing quality and size range - I can tighten to account my 31” bust with no bounce. Fits a bladder and gear in the large rear pocket, plus you can have two flasks upfront. The shoulder pockets fit a phone and all the gels you need for several hours between aid stations. Pole anchors too. Bladder not included.
