As many of you might know, Ultimate Direction has went in the direction of getting ultra runners to design packs that suit them (as well as their philosophy in running) to gather a wide range of packs that will suit the needs for different kinds of races.
They have also made some interesting and surprisingly informative videos on the packs.
The Anton Kupricka vest.
The Scott Jurek vest.
The Peter Bakwin vest.
Really nice vests, arent they?
