Our Analysis and Test Results
The REI Flash 55 is an incredibly worthy contender in the fight to see which backpacking backpack for women is the best on the market. At only 2.7 pounds with removable pockets, you can get this pack down to a scant 2 pounds if you are motivated to shed weight. Made of thin, ripstop nylon and featuring a roll-top closure, this is one of our top recommendations for newbie backpackers who want a well-featured trail companion without over-purchasing.
Performance Comparison
Comfort
REI has incorporated a strong, stable suspension system for a lightweight pack. When fully loaded with up to 33 pounds, the weight is well distributed to your hips and doesn't sag onto your shoulders. We found that the frame didn't provide as much support once we added more than the recommended amount of weight, preventing the Flash from succeeding as a “super hauler.”
The Flash has a smaller-feeling frame than some of the other packs we tested, making it suitable for smaller-bodied people. Compared to some of the more ruggedly built packs in our lineup, the Flash feels unimposing and comfortable, even on our 5'2" tester. REI makes four different sizes of the Flash, all of which come with an easy torso adjustment system on the back panel. This ensures that a wider variety of body shapes and sizes can find the right fit. The hip belt padding is fixed and constructed of densely woven textile, making it feel stiffer than some. The padding on the back panel is also dense but provides comfortable and unintrusive support. The perforated mesh adorning the back panel helps air flow through, further adding to this pack's overall comfort.
Ease of Use
When it comes to backpacking backpacks, our testers find that keeping things simple is usually the way to go. Our lead testers prefer backpacks with fewer organizational features, which is part of why the Flash is one of our highest scorers in this metric. Whether you are just packing up or deep in the backcountry looking for your extra fleece to stay warm, this pack is user-friendly.
The Flash features a Packmod design. This design lets you easily move or remove additional pockets for a customizable backpacking experience. The lid, hip pockets, and mesh cellphone pocket can all be easily moved to your liking, ultimately lessening the weight of this already lightweight pack. The drybag style roll-top closure is easy to use as an access point and a compressive feature. The wide mouth of the Flash makes it super easy to sift through your gear in a loaded back. While lacking additional access points, having the ability to open the top so wide makes accessing your gear a lot easier.
The Flash has bilateral side pockets in addition to its mesh water bottle pockets. These ripstop nylon pockets and beavertail exterior pouch keep quick-draw items within reach without so much as a zipper in the way. Beyond just the ripstop pouches, each side of the Flash has a mesh pocket that is slanted forward specifically for easy access to your water bottle.
Weight-to-Volume Ratio
At 2.7 pounds, this model is lighter than most but still has a strong enough frame to carry moderate loads up to around 30 pounds. In fact, the Flash outperformed many packs that weigh more with burly suspension systems. While none of the packs we tested made our heaviest loads feel lighter, some of them certainly felt more comfortable than others, the Flash included.
Even with a slightly smaller capacity than the other packs we tested, the volume-to-weight ratio of the Flash is impressive. More than just throwing up impressive numbers, though, the Flash remains comfy for the long haul when fully loaded. To keep the weight of the Flash comfortable, it is important to use the compression systems that are built into the pack. Since the Flash has a more minimalistic design and the bulk of the gear gets stowed in the main pocket, our heaviest loads were a bit lumpy and off-kilter. Once we used the external compression straps and really tamped the roll-top upper down, we felt significantly more balanced.
Adjustability
The Flash is a standout choice in this metric. Not only is the sliding torso adjustment easy to use, but the greater availability of sizes offered by REI makes it easy to ensure a proper fit from the get-go.
Like many lightweight packs, the hip belt padding is fixed. The padding comes fairly far around the pelvic bones of average-sized women, but larger-hipped women will find that it stops short of where they may like for comfort. The thick webbing offers plenty of extra length, but without extra padding, it can be less comfortable as the miles add up.
Should You Buy the REI Flash 55?
If you are a beginning backpacker who wants a pack that will comfortably get the job done without being too much pack, the Flash is a great backpacking pack to consider. Its approachable frame size, modular organizational system, and easy-to-use features make it a great choice and a great value. Lightweight adventure enthusiasts, rejoice! The lightweight Flash could also be a fantastic choice for your next adventure.
What Other Backpacking Backpacks Should You Consider?
If you are looking for a great pack on a budget but aren't sure if the Flash is right for you, we recommend checking out one of our absolute favorites, the Osprey Eja 58. The Eja is similar to the Flash in that it is lightweight, but the Eja more keenly places comfort at its center. For a bit more money, the Eja is a wear-all-pack due to its comfortable back panel and lightweight fit. Another favorite is the Osprey Renn 65, a comfortable and rugged pack that is well-suited for smaller bodies and costs about the same. The frame of the Flash makes it comfortable on smaller statures, but the Renn takes a different approach. The design of the Renn spreads the weight of the load out laterally instead of creating a vertical tower of gear on your back.
