Diablo is killer
I can fit a 2L Platy in the pack w/o a problem. Great pack because of its functionality, compact size, appealing style and superior quality.
Light
Gregory has the basic function down, for biking with a bottle of water and some tools and the thing I like and got it for is the straps that angle out so there is not an issue of digging into the shoulders on a long ride...
Real nice.
Wish it had a place to put a water bottle.
Hydration capacity limited
The concept is a good one. But the downfall of this pack is the itty bitty capacity of the hydration sleeve. I haven't been able to find a hydration bladder small enough to fit. It must take a 1 liter or less, which is not much water. The ideal use may be for very short-trail runs. Otherwise, consider a larger hydration pack.
