Backpack Rain Cover Buying Guide - Get The Best Waterproof Pack Cover
Why Get a Backpack Rain Cover?
Though many backpacks are made of water-resistant fabric, they are rarely 100% waterproof. A rain cover can offer you the extra protection needed to keep your gear safe from moisture, eliminating the risk of soggy clothing and fried electronics.
A waterproof backpack cover is easy to carry since it folds down small enough to tuck into a spare pocket when traveling. When needed, you simply pull it out, slip it over your bag, and secure any closures there are to hold it in place.
The beauty of these backpack covers is that they can be used for to cover your bag while backpacking, hiking, camping, biking, or even walking to school on a rainy day. They are lightweight, so you won't even notice it's there, though you'll be thankful for it when the rain starts pouring down on you.
What Do You Need - Waterproof Backpack vs. Pack Cover?
Waterproof backpacks are the ultimate gear choice that will keep all your gear dry, but there area a few reasons why you may want to go with a waterproof pack cover instead.
Most waterproof packs are made of a fully waterproof material, which is just what you need to keep your gear dry. However, they are heavier and less supple than traditional backpacks. You also give up some functionality with storage options in many waterproof backpacks.
The other problem is that punctures can happen at any time. Once a hole forms in your pack, the waterproofing goes out the window. Seams consist of hundreds of holes that could also leak if not fully taped.
Having a waterproof backpack rain cover can be a good solution, especially if you love the pack you currently have and don't expect to be using it in extreme wet weather. They are also made of nylon or polyester, usually with some type of waterproof coating, which keeps the water out without adding extra weight.
They are versatile enough to fit over a variety of pack shapes and sizes. But like the backpacks, they can be torn, reducing their effectiveness if not properly repaired.
Rain covers also have the added benefit of being compact enough to be stored in a small pocket until they are needed. They cover almost the entire pack, and many even have reinforced bottoms for added protection if you put your backpack down on a damp surface.
When to Use a Backpack Rain Cover
The best backpack rain cover is versatile, so you can use it for any type of activity where you might need a bit of protection from wet weather.
Hiking and backpacking are the obvious uses, but you can also use these covers when riding a bicycle or a motorcycle. A backpack full of books for school or the library can also use some protection.
You can even use it when you're boating, fishing, or camping to protect your clothing, electronics, and other essential items.
The added benefit of a backpack cover for rain is that they come in a variety of sizes and colors, plus are so compact they can be folded down and tucked away until you need them. When the rain starts, pull it out, slip it over the pack, and you're back on your way in only a minute or two.
What to Consider When Choosing the Best Backpack Rain Cover
Waterproof vs. Water Repellent
When a material is waterproof, this means that the rain will glide over the outer surface but won't soak into the fabric. Water repellent will have a similar effect in light rain, though it won't hold up against a heavy downpour.
When choosing a rain cover, you need to consider the season and activity you plan to use it for. In drier areas with little to no rain, you won't need the heavy duty waterproof cover. If you plan on going out for a short hike, this may also be good enough to protect you from an unexpected shower.
Longer backpacking trips will require a waterproof cover. You don't know when the weather will change and a heavy rain will soak you down. Plus, it will ensure you'll have some dry clothing to change into when you get to your site.
Capacity - What Size Pack Do You Have?
Like backpacks, rain covers come in a wide range of sizes to choose from. They cover smaller packs with a capacity of 10L to the larger 75L expedition models. When you pick one, you need to make sure it will cover the backpack you are using.
But just because it claims to fit your backpack doesn't mean you should just pack it and go. Open it up and slip it over your pack to make sure it fits properly. If it seems a bit too snug, take the cover back and get one size larger.
Most of them can be tightened for a secure fit, but if it is too small, you risk leaving some areas of the backpack exposed to the elements.
Fit
When you wrap your backpack in the best backpack rain cover, it should have a tight fit, wrapping around the top, bottom, and sides securely.
Some of them have elastic rims to hold it on, and if this is the case, you want to make sure it will hold against the wind if it should pick up. A loose fit won't' keep the rain out, making the pack cover a useless addition to your gear.
Straps and drawstrings will help since you can tighten the backpack rain cover as much as you need to. But even with these, you want to make sure there are no gaps in the back that could let water in.
Durability
The best backpack cover will be made of lightweight material that won't tear at the slightest scrape. They are wear-resistant, so you can use them repeatedly out in the rugged wilderness without leaving your gear exposed.
A backpacking rain cover is also scratch-resistant, so you won't end up with a large tear if you accidentally brush your pack against a branch or place it down on some rocks.
Many of them are also seamless, so you don't need to worry about threads coming loose and leaving open areas in your rain cover. Leaks in your pack cover will also be reduced thanks to this feature.
Materials
There are two materials used most often in your average backpack rain cover. Both are lightweight and have their own benefits and flaws.
Nylon is popular since it is durable and stretches as needed. It resists water, abrasions, mold, mildew, and stains. It is also easy to clean if it gets dirty during your travels, which is quite likely.
The downside to nylon is that it isn't recyclable and is prone to fading if exposed to sunlight. But it is the stronger of the two.
Polyester is also durable, though doesn't stretch as easily. But it also won't shrink, so it will fit you pack no matter how often it gets wet. This material also dries fast and resists water, mold, and mildew.
It won't fade, is easy to clean, and can be recycled if it becomes damaged. The issues are that it could hold a stain from oily substances.
Color
Sometimes when people choose their outdoor gear, they consider the features but don't put much thought into color unless it is to suit their style. This is the wrong way to look at this since the color of your rain cover could either help or hinder you in an emergency.
Think of it this way. If you get lost in the woods and the sun is going down, a black backpack cover won't be visible to those looking for you. A bright neon orange or yellow one will help them spot you though, even in the fading light.
Many brands of waterproof backpack covers also have reflective graphics on the back. Though they may look cool, style isn't the reason they are there. These will also help those around you locate your position since the reflective material will catch the light of a flashlight or even the moonlight overhead.
Price
The price of your new waterproof backpack cover will depend on the material it is made of, as well as the size of the cover.
Nylon and polyester are the most durable materials, so they will cost a bit more than other types. But their versatility and strength make them well worth the cost.
Buying a small cover to fit over a 10L bag needs less material to make it then a large 60L capacity rain cover. Less material means less cost to produce it, which could also affect how much you pay for it.
But there are cheap models available. If you are traveling on a budget, it is possible to find decent rain covers under $15.00, but these may not have the adjustable straps and the thicker material of the more expensive brands. They will still do the job they are intended for, though.
The Bottom Line
Getting caught in the rain when you're far from home, or any other type of shelter, can ruin your gear as well as your day. Having the best backpack rain cover as part of your supplies can keep the essentials strapped to your back dry until you can get indoors.
With so many to choose from, it may be hard to find the right one. That's why it's important to pick a rain cover according to your needs and your budget.
Our pick for the best backpack rain cover is the Osprey UltraLight Raincover. I love Osprey backpacks and it's a brand that stands behind their products 100%.
