Price
Hiking rain covers are very affordable. Even high-end models from very well known brands rarely break $50. When compared to the price of a good hiking pack waterproof backpack covers are almost negligible.
You can find quality rain covers for a steal of a deal if you look hard enough.
Water-Resistance
The bulk of rain covers are water resistant rather than waterproof. In order to qualify as a waterproof cover it would need to be able to stand up to at least partial submergence.
Most rain covers only protect the part of your bag that’s exposed to the elements and do nothing to protect your stuff from submergence. That’s not really a bad thing though.
We’ve reviewed fully waterproof duffel bags, backpacks, and dry bags before, they aren’t usually something you’d want to lug around on a long hike.
Water resistant rain covers are perfectly adequate for protecting your gear from a downpour while out hiking and camping.
Should You Use a Water-Resistant Spray
The materials used in your rain cover go a long way to making them water resistant, but they aren’t perfect. If you’ve noticed that your rain cover has started to seep a bit, especially around any seams, it’s not a bad idea to give it a thorough coating of an outdoor waterproofing spray or wash.
We’ve done a review of several great tent and gear waterproofing sprays. Check it out to find the best one for your rain cover.
Material Denier and Durability
The bulk of waterproof backpack rain covers are made using either nylon or polyester. Nylon is slightly more expensive on average but is very durable and can stretch slightly for the best possible fit.
Nylon rain covers are highly water resistant and easy to clean. They will wear out eventually but only after a long working life.
Polyester is a bit cheaper than nylon on average and is also highly water resistant. It’s not quite as durable as nylon but does offer acceptable performance at a reasonable price.
Denier is the metric used to measure the toughness of a bag. For a hiking backpack rain cover you want to balance durability with flexibility and weight.
If you’re doing light hiking across relatively smooth terrain 150-200D is perfectly acceptable. If you plan to do long duration hikes across rough terrain you should go for a rain cover that’s more resistant to damage.
300D is a good place to start, though you’ll see examples that are 400D, 500D, and even 600D. You may also encounter rain covers measured in Tex units. A Tex is a unit similar to a Denier but based on an actual volumetric measure.
A good way to roughly compare the two is to multiple Tex by 9 to get Denier.
Whatever material you decide to go with we highly recommend you choose a ripstop version. Ripstop fabrics are specially stitched to prevent a small tear from becoming major damage.
Coating
Because the majority of rain covers are made using woven plastic strands they’re often coated with a waterproofing material. Durable Water Repellent (DWR) coatings are extremely common, as are similar coatings such as siliconized nylon and polyurethane (PU).
You’ll likely need to replenish the strength of these coatings on a regular basis.
Size
Sizing your rain cover is one of the most important factors to consider when picking one out. You need one large enough to fit your backpack without being too big for a snug fit.
General purpose rain covers not designed for a specific bag usually offer a method to cinch down the body of the cover against your bag. Rain covers will give you a range of pack sizes that they’ll protect.
This is generally shown in liters or cubic inches. If you aren’t certain what size you need for your pack we recommend you go a size up just to be safe.
It’s always possible to cinch in or strap down a too large rain cover. If it’s too small though you’re pretty much out of luck.
Straps and Adjustable Drawstrings
General rain covers designed to fit a range of packs often have straps, drawstrings, and elastic strips. This allows you to customize the fit of your rain cover to better match your specific hiking pack.
Common methods include a criss-cross style pair of straps that fit along the back of your pack. This prevents the rain cover from sliding off.
Color
You can choose from a vast array of colors and patterns depending on the rain cover brand you choose. If flying under the radar is important for you many manufacturers offer camouflage rain covers.
For hunters, or those hiking during hunting season, a bright color such as blaze orange or red helps draw attention to you and prevent accidents. Some hikers prefer earth tone rain covers that allow them to hide their packs on the side of a trail while going for a wash or taking a break.
Dustproofing
Rain and water aren’t the only things to worry about when out hiking. If you’re in the desert or a similarly dusty, windy area sand, dust, and dirt can be a big concern.
The last thing you want is to find out your clean clothes and comfortable sleeping bag were filled with sand during the day. Check prospective rain covers to find out if they offer protection against dust, dirt, and sand.
This also makes it a whole lot easier to keep your expensive hiking pack clean. It’s a lot better to get mud and grime on a $20 rain cover than a $200 pack.
Rain Cover Pockets
Many rain covers are designed with quick-access exterior pockets. This allows you to put items like snack bars or waterproof maps within easy reach.
It allows you to access them without removing the rain cover from your pack when it’s raining.
Final Thoughts
When it comes to choosing the best waterproof backpack cover you have to consider where and how you’ll use it.
If you’re a cyclist or runner you’ll likely need to prioritize visibility and compactness. A distance hiker needs performance, durability, and packability above all else.
As long as you know how you intend to use your rain cover it’s easy to pick out the version that works best for your needs.
