Part of the beauty of fell running is really just the absolute minimal necessities. In that way, these shorts get the job done. They cover up what, legally speaking, needs to be covered up. But, that doesn't mean little creature comforts don't make a difference. I feel that's where these shorts fall, uh, short? Although, Mammut calls them "running pants" on their website, which is fun, and I might take up, but has nothing to do with the effectiveness of these running shortpants. These shorts stack up only so-so against other shorts with much more storage & pockets cut a lot more specifically for things like gels, small flasks, etc are available from the likes of Salomon et al.
