I had a credit at Second Ascent and I also unloaded some packs, so it was time to get one of the Exped's and give it a try. I've had a long history with UL "stuff sacks with straps" style packs and I have yet to be impressed by one. I've been through the Flash 18, Flash 22, Verto 26, and a whole string of CamelBak, GoLite and other hydration style packs. Meh. Most ride like a "rabid raccoon" perched on my back and bouncing around. That and the fact that as much I as try, 18-20 liters just isn't enough space for me, even in a day pack.
So this pack is 11.4oz/32g, with an advertised weight of 11.6oz/330g. Good job, Exped! Volume is rated at 1525 cubic inches/25 liters, measuring 20"x11"x7.8" (53x28x30cm). That looks reasonable next other packs of 25-29 liter volume.
It adopts the "turn it inside-out and stuff it in a self-storing pocket" design. It does that, tucking into the top lid, but I wish they made with the lid zipper on the outside when deployed rather than inside.
The lid has dual zippers and hinges at the front, allowing the user to leave a gap in the zipper to route a hydration hose out the back and there is a sleeve inside with a single centered reservoir hanger clip inside. It opens large to give full width access to the innards.
It has a removable waist belt (1oz), a sternum strap on sliders, dual daisy chains down the front and one tool lop and one stretch mesh pocket on the right side. The waist belt uses toggles and D-rings for the connection with 3/4" webbing and a buckle much like the ones on a sternum strap on a heavier pack. It's good for basic stabilizing, but no weight bearing of course. Those D-rings could be handy for lashing the pack to the top deck of my bike rack. There is a folded and stitched webbing haul loop above the shoulder straps that is about 5" wide– you can get a gloved hand in there. The daisy chains are backed inside with grosgrain tape and bar tacked.
The shoulder straps are 2-3/4" wide with a diamond perf foam bonded to breathable mesh with ripstop fabric on the top side. The shoulder straps on these light packs are the litmus test for me, most of them collapsing and becoming uncomfortable with anything north of 10 pounds. These are wide enough to make me hopeful and long enough to get a good wrap around my pecs There are webbing loops just above the sternum strap sliders to corral a hydration hose or hang a sunglass case or tether a compass.
There is one side pocket on the right (sigh). Two would be better. It's about 6" wide and 7" tall. In the photo below, it will handle a one liter platy bottle, which is reasonable for a pack this size. But I still want two. The North Face Verto 26 commits this same sin, but my impression is the Exped ha a bit more room. I guess if you want to haul more you can use the internal sleeve and save this one for gloves, or beanie, windshirt, bandana, etc.
The sternum and should straps have roll-n-velcro management for excess strap length; the waist belt uses elastic webbing sliders.
I don't like to do surgery on packs, but you could trim straps, cut out the bladder sleeve and hanger and tool loop and leave the waist belt behind and drop the weight 2-3oz. The belt is 1oz alone. I would ADD a bungee cord array in the daisy chains. There is no pack panel padding or mesh. I can add some 5mm EVA foam (AKA sit pad), but it will be a sweaty little pack, just like others of the same construction.
Comes in blue and Exorcist green too.
So far, not a bad little pack for $50. What would I do with it?
Day hiking
Urban hiking/commuting
Travel
Bikepacking– worn, or lashed onto my rear rack. Good for hybrid bike-n-hike trips
SUL summer overnights
The proof will be getting my typical day hike kit in this and test those shoulder straps. Soon.
