What the REI Co-op Duck's Back Pack Rain Cover - Small is
The REI Co-op Duck's Back Pack Rain Cover - Small is an external rain cover that stretches over your backpack to add a protective shell in wet weather. Instead of relying on your backpack’s fabric coating to fend off rain, the cover creates a dedicated barrier that helps keep water from working its way in.
For school use, the big benefit is protecting the places most backpacks fail first: zipper tracks, seams, and corners that get saturated when you’re stuck walking in steady rain. If you carry paper, a laptop, or a charger, a cover like this can be the difference between “a little damp” and “everything inside is wet.”
It’s also a low-effort upgrade. You don’t have to replace a backpack you otherwise like. You just keep the cover packed away until you need it.
Why it stands out
The main reason to buy the REI Co-op Duck's Back Pack Rain Cover - Small is simple: it gives you a quick layer of protection when your backpack is only water-resistant. A lot of school backpacks can handle a drizzle, but they’re not built to stay dry through a real downpour, especially around zippers and stitching. A cover addresses that weakness directly.
It’s also designed to be easy to live with. A rain cover that’s bulky or annoying tends to get left at home. This one is meant to stash small so it can stay in your bag full-time, ready for the day the forecast is wrong.
Finally, fit and returns matter with rain covers. If your backpack is close to the edge of the size range, being able to swap sizes easily can save you from ending up with a cover that’s too tight to pull on quickly or too loose to stay put.
What it is like to own
In day-to-day school life, a rain cover earns its keep by being boring. You keep it tucked in a pocket, and when the sky opens up, you pull it out and slip it over the pack. That’s the whole workflow. The value is that you can do it quickly outside a classroom, at a bus stop, or right before you start biking home.
A cover also changes how you pack. You can stop treating “waterproof” as a feature your backpack either has or doesn’t have. With a cover on hand, you can carry paper notebooks and electronics with more confidence even in a standard school backpack.
Storage is the other everyday win. Because it’s meant to be packable, it’s realistic to keep it with you all semester instead of only bringing it on rainy days.
What to know before you buy
Sizing is the big one. Rain covers work best when they fit your backpack properly. Too small and it’s a struggle to get on when you’re in a hurry. Too large and it can shift around, leaving parts of the bag exposed. If your backpack is right on the edge of what “Small” should cover, plan on double-checking fit and being ready to exchange if needed.
Also, a rain cover is not the same thing as a waterproof backpack. It’s an outer layer that helps keep rain off the bag and away from common leak points. If you routinely deal with heavy rain, long bike commutes, or you’re carrying expensive electronics every day, you may still want internal protection (like a dedicated waterproof sleeve) as backup.
Last, remember what it protects. A cover is about rain from above and around you. It’s not a magic shield for every situation, like setting your bag down in a puddle.
The specs that matter
This goes over your existing backpack, so you can keep the bag you like and still add rain protection when you need it.
If it fits in a pocket of your backpack, you’re more likely to actually have it when the weather changes mid-day.
Those are the weak points on most school backpacks. Covering them is often what prevents wet notebooks and electronics.
Many backpacks repel light rain but still leak in a downpour. A cover is a practical fix without buying a new pack.
Fit is everything with rain covers. Easy exchanges reduce the risk of ending up with the wrong size.

You carry a laptop in a regular school backpack

You bike or take the bus and can’t stay under cover

REI Co-op Duck's Back Pack Rain Cover - Small FAQ
Is the REI Co-op Duck's Back Pack Rain Cover - Small worth it for school?
Yes if your backpack is water-resistant but not waterproof and you carry paper or electronics. It’s a small, simple add-on that can prevent the most common “soaked through” problem during a sudden downpour.
Will a rain cover keep my backpack completely dry?
It’s meant to add a protective layer against rain and help keep water from soaking through weak points like zippers and seams. It’s not the same as a fully waterproof backpack, and it won’t cover every situation (like setting your bag in standing water).
How do I know if I need Small or a different size?
Fit depends on your backpack’s overall size and shape. If your pack is near the edge of the size range, plan on checking fit carefully and choosing a retailer with easy exchanges so you can size up or down if needed.
Do I still need a laptop sleeve if I use this rain cover?
A cover helps a lot in rain, but it’s still smart to protect electronics inside the bag if you can. If your laptop is expensive or you commute in heavy weather, pairing a cover with internal protection is a safer setup.
Is this only for hiking backpacks, or does it work for school backpacks too?
It can work well for school backpacks as long as the size fits. The benefit is the same: an outer layer that helps keep rain off the bag and away from seams and zippers.
Should you buy the REI Co-op Duck's Back Pack Rain Cover - Small?
Buy the REI Co-op Duck's Back Pack Rain Cover - Small if you rely on a normal school backpack and you’re tired of gambling with rain. It’s a practical, low-cost way to protect the stuff that matters most, especially notebooks and electronics, without replacing your bag.
Skip it if your backpack is already truly waterproof or if you know you won’t use it consistently. Otherwise, this is one of those small upgrades that can save you from a very annoying, very avoidable wet-backpack day.
