Osprey backpack rain covers: find the best one for your pack

by Sigita B | Last Updated: November 4, 2020

Once you have found your perfect backpack, there is one accessory you need: a rain cover. It is an overlay made of thin, durable fabric that protects your pack from the elements. Not only does it protect your backpack and hiking gear inside of it from water, it also offers protection from dust. Since rain covers fulfill several different functions, keep reading this short guide and learn what to look for in a rain cover, especially if you are shopping for your Osprey backpack.

Why do I need to buy a rain cover for my backpack?

When you buy a hiking backpack, most of them will come with a rain cover that fits the pack’s dimensions. However, after some use the cover might get lost or maybe it got a rip while on the trail. If something happens to the original rain cover that came with your pack, you don’t have to invest in a new backpack – you can just buy the cover separately.

Waterproof vs water repellant rain covers

One thing to look out for: whether the rain cover you have set your sights on is waterproof or water repellant. Waterproof materials do not soak up any moisture and therefore will hold up even in heavy rain. However, water repellant covers can only protect your belongings from light rain. Hence, they are good for hiking in dry weather. If you are unsure about what weather conditions to expect, go for a waterproof rain cover.

Osprey rain cover’s sizing and weight

Osprey waterproof rain covers are compatible with Osprey backpacks, although you can make it work with different packs as well given the measurements match. However, it is best if rain cover is the same brand as your backpack so that it is the right shape and fit.

Osprey rain covers come in five sizes from XS to XL accommodating backpacks with capacity from 10 to 110 liters. They are ultralight and can be folded to fit into a small carry case that will hardly take up any space.
