It folds up easy and weighs nothing. I have been doing this for years. Very fortunate to live in Washington where there is clean, clear water on most of the trails & mountain gravel roads up here. **Q: osprey duro 15, will it fit the front pockets?** A: Hi there! Our flasks and reservoirs will fit most running vests. Please see below dimensions and compare to that of your running vest to see if they are compatible.
