Four Stylish REI Backpacks

REI Backpacks Featured Image

We love REI! They have an awesome selection. They carry high-quality products. Their customer service staff is always extremely friendly and knowledgeable. Whether you’re looking for boots, bike helmets, or a new balaclava, they’ll help you find a product you enjoy. Today though, we’re going to be highlighting four REI backpacks that are sure to turn heads on your next outing.

Before we get started, we’d like to add a little disclaimer. As you read through these four reviews, keep in mind what purpose you intend to use your new backpack for. Also, consider the gear you’ll be carrying. These are ALWAYS two of the most important factors when considering which backpack is right for you!

The REI Co-op Ruckpack 40 Pack

Men’s and Women’s

REI Backpacks - rucksack 40

This first REI backpack we’re going to talk about is the Ruckpack 40. Why 40? Because it will hold 40 liters of gear! This is an awesome pack for the on-the-go adventure traveler. With dimensions of 24 x 13 x 10 (in inches), it’s small enough to come aboard your next airline flight as a carry-on and still big enough to carry a 15-inch laptop and all the other supplies you’ll need for your travels.

The total gear capacity of this pack is 2,440 cubic inches. For a little perspective, 2,440 cubic inches is roughly equivalent to three-and-a-half NBA Men’s standard-sized basketballs or, for our backpacking beer drinkers out there, about 2/3 of a standard-sized keg. So, you’ll either be able to pack three and a half basketballs or 2/3 of a keg of your favorite beer!

This REI backpack is engineered with a spring steel internal frame and boasts exterior material of 210-denier nylon ripstop fabric. Just a quick aside, “denier” is a measurement that tells us the fiber thickness of individual threads used in the creation of fabrics. In general, fabrics with a higher denier count tend to be more durable.

Now on to the fancy features of this REI backpack. Two exterior pockets make accessing your travel essentials easier than ever when you’re on the go. The Ruckpack’s full-zippered design also allows for easy packing and convenient access to your laptop in the airport or that extra layer when the clouds roll in on the mountainside.

But here are the kickers! A stowable rain cover makes for easy deployment in inclement weather, the zippered back panel protects your backpack’s straps while in transit, and lockable zippers keep your belongings secure wherever you roam!

The REI Co-op Flash 45 Pack

The second pack we’re going to detail today is the Flash 45. With a gear capacity of 45-47 liters, the Flash 45 is a little larger than the Ruckpack above. It’s also manufactured from 420-denier ripstop nylon, so it’s designed for a bit more rugged adventures. The Flash 45’s dimensions are 13 x 26 x 9 (in inches), so it’ll have to stow under the plane if that’s your designated travel method.

The Flash 45 REI backpack is designed for the weekend warrior hoping to make his or her excursion just a bit more comfortable. REI’s patented Uplift™ Compression technology brings the pack load closer to your center of gravity. This helps to improve balance and stability. The adjustable, 3D-contoured hip belt is also designed with your comfort in mind.

For those of you who always tend to overpack, the Flash 45 is a great option. The removable top lid allows for some freedom in determining pack volume. Hipbelt pockets give you a chance to store chapstick, lighters, lozenges, or those sugary candies you can’t live without while backpacking. The large mesh pocket and various attachment loops on the front of the pack also allows for easy storage and security of the items you need frequent access to while adventuring!

The REI Co-op Trail 70 Pack

The third REI backpack we’ll cover is the Co-op Trail 70. This pack is designed for long-term backpacking trips, but it’s also a great option to use as that extra checked bag on your next extended vacation. With a total gear capacity of 4,271 cubic inches, our enthusiastic drinkers could fit an entire keg of their favorite brew into this one and still have room leftover!

With an internal frame engineered of aluminum, the Trail 70 weighs only 5 lbs., 2 oz. when empty. Its top-loading design allows for easy organization and storage of your backpacking gear. The Trail 70 also boasts a bottom-access compartment designed specifically for quick and easy access to your sleeping bag.

Like the Flash 45, the Trail 70 REI backpack is manufactured with 420-denier ripstop nylon. One feature the Trail 70 boasts that the Flash 45 does not, however, is its stowable rain cover, which is stored in a zipper pocket just above the sleeping bag compartment.

With its adjustable 3D-contoured hip belt, removable lumbar pad, and ventilated back panel, the Trail 70 is great for many torso sizes. Perhaps most importantly, the Trail 70 will accommodate your exterior hydration pouch through a quick-snap closure located on the back panel!

The REI Co-op Tarn 12 Pack

The last REI backpack we’ll discuss today is the Tarn 12. We can’t go home for the day without doing one for the kids! The REI Tarn is perfect for ages 5 to 8 and it was designed with kid comfort in mind. The idea behind the Tarn 12 is simple: if your kids are comfortable when they’re hiking, then they’re having fun and they’re likely to do it again!

With a 12-liter capacity and 13 x 9 x 5 dimensions (in inches), it’s the perfect size for your kiddo! Water bottle pockets that can be accessed without removing the pack make it easy for you to encourage proper hydration on your adventure. The Tarn also boasts a buckled hip belt that helps to distribute weight on longer day hikes and built-in airflow ventilation that’ll keep your kids cool on those hot summer days!

The REI Co-Op Advantage!

Regardless of the pack you choose, we think shopping at REI is always a great idea! As an REI Co-op member, you’ll receive a 10% dividend on every item purchased in a given year. REI will then send you a gift card with your total dividend amount at the end of the year. They usually include a few 10% or 20% off coupons as If you’re not already an REI Co-op member, make sure you sign up next time you’re in the store or online.

It’s like getting free stuff! Or at least getting rewarded for the gear you’ve already purchased. Brand loyalty can be hard to come by these days, and it’s nice to find a company that’ll let you know it appreciates your business with more than just a bunch of spam emails mucking up your inbox!

    Hello, I really appreciate your time and effort on writing about these REI backpacks which is something I’ve been looking into. I plan on going hiking this spring and I’d really like to get one of these on my trip.

    The way you laid it out is perfect and informative, my favorite is the The REI Co-op Trail 70 Pack, I really like the long and tall style of the bags and the fact it can accommodate a hydration pouch which I’m not sure if I’ll get yet.. what’s the benefit of that over a traditional water bottle? I might give this one a try and see how it works for me. Thanks for bringing it to my attention!

      Hey Son! The benefit of a hydration bladder over just having a water bottle on the side of the pack would be the ability to drink while you keep hiking. In other words, you’ll be able to stay more hydrated without stopping to pull your water bottle out every hour or so! Does that make sense?!

  2. Travis

    I am a big fan of REI backpacks. I am looking for a  new one since my last one finally has been worn out after many years and lots of adventures. They all look nice, but I am going with the Co-op Trail 70, I always like to get the bigger packs because you never know when you will need the extra room. I cannot believe that it is only 5 pounds, 2 ounces when it is empty! It is amazing how good their packs are, thank you so much for reviewing these!

      You are very welcome Travis! I’m very much like you and like to get bigger packs because I like to have extra room for reading and journaling material when I head out on the trail. I’m not an ‘ultralighter’ by any means!

    As a kid we used to go out to Colorado and stay at the YMCA of the rockies.  Loved going there and then hiking on the mountain trails.  I wish we could have had such nice packs as these even the kids one looks awesome.  One question on the kids pack and the first one the 40 pack.  Are they not made with ripstop material to keep the price down?  And the material is not waterproof so you would have to take along something to keep dry if you get caught out in the rain?  Thank you for the great info on the packs.

      Hey Douglas! You are correct on the idea that you’d need a rain cover to keep the pack dry if you got caught in the rain. But that’s pretty much universally true for backpacking packs, even if they claim to be “waterproof.” I can’t speak to why Osprey didn’t utilize the ripstop material in the Kid’s pack, but I do think that’s one of the reasons why that pack is offered at a slightly lower price. Thanks for the questions and I wish you happy hiking!
