NathanVaporKrar 4L Men's Race Vest Hydration Pack : Lightweight : Running

Overall, great vest. Has become my go-to for any longer length.Pros- Good fit with plenty of adjustability. Doesn't move around much at all.- Stretchy, comfortable fabric- Nice little features such as the bottles, and split back pocketsCons- Side adjustment straps run over the top of the side pocket, making the pocket hard to access- Cap on the bottles is hard to screw on- A little expensive

The most comfortable fit ever doesn't move around endless pockets , top piece of kit ,well after all it was designed by robb krar highly recommend this product
