Reviews

An almost perfect fast pack

"The only improvement I’d make to this pack is the front pocket design. The mesh pockets are deep, which is good, but they don’t hold bottles or a phone very well, and snacks bounce when running, so I’m not sure what’s best kept there. I prefer a tight-fitting front pocket with a zipper on one side to hold a phone for easy access to maps. The small mesh pockets (above the larger front pockets) hold an inReach perfectly, however! Everything else about this pack is spot on for trail running or fast packing. I was concerned that the fit wouldn’t work for me since I’m relatively small (5’7”/170cm 135lbs/61kg) and have a short torso, but I’m impressed by how well the adjustable straps on the sides and front bungee closures work for getting the fit dialed. The pack hugs my torso and doesn’t move around at all. It feels considerably more comfortable than other running packs of the same size and smaller that I’ve used for years, even when it’s fully loaded with 3L water and gear for a full day out."

Versatile ++

"Parfait pour les courses d’ultra distance en running ou à vélo, le snowboard / ski de rando. Prend peu de place dans un Duffel bag pour prendre l’avion ou autre. Finition comme toujours, impeccable :)"
