**Q: Will they take a Katadyn BeFree filter?**
A: Haven't tried putting the filter in, but I carry the BeFree collapsable water filter and flask with me on most of my runs, hikes, and long gravel rides.  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. 

Dimensions: 7.3 x 2.3 in
