What is REI Co-op Flash 55?

Rei co-op flash 55 is an all-around great value backpacking pack among an impressive backpack lineup. It carries a medium load well but is not intended for loads much over 25-30 pounds. Even with a ton of pockets and features, the pack is super lightweight due to thin fabrics and a lighter-duty suspension.

It, top lid, and shoulder strap pocket are all removable to save an additional 7 ounces, and the side compression straps can be (re)moved to better suit the pack’s load, regardless of the trip.

The Flash is quite comfortable. We found this pack hugs your body well. As long as the load is under the 30-pound weight limit, we never complained about how this pack felt, even on our longest days on the trail.

It feels solidly planted on your back, and the frame effectively disperses the load between the hip belt and shoulder straps. rei co-op flash 55 pack

REI’s Pack mod design utilized in the Flash 55 is excellent. It has a handful of clever features that can be removed or adapted to help make packing for any trip a breeze. The modular aspects of this backpacking backpack include two hip belt pockets (one mesh, one ripstop), a mesh shoulder strap pocket (seemingly made specifically for a smartphone), two side compression straps per side, a top lid, and a tool attachment loop.

How much weight can a Rei Flash 55 hold?

We loved how lightweight the Flash is. With the weight as low as it is, you’d think it wouldn’t carry weight very well.

The newest version of the Flash features an easy way to adjust the torso length to be taller or shorter. This way, you can fine-tune the fit to make the pack more comfortable. REI Co-op Flash 55.
