Kelty Best Backpack Rain Cover

I am an avid outdoorsman, always on the lookout for gear that can stand up to the elements. On a recommendation, I decided to try out the Kelty Backpack Rain Cover on my recent 10-day hiking spree across the Appalachian Trail. This rain cover quickly became an indispensable part of my gear.

The cover is crafted from 190T taffeta nylon ripstop and treated 600D polyester, making it a lightweight yet robust barrier against the relentless rain. Its durability was proven during a couple of unexpected thunderstorms that could have otherwise drenched my gear. The internal adjustable pull cord was a godsend, allowing a snug fit around my pack, keeping it securely in place even as the winds howled.

I chose the large size since my pack often teeters around 60 liters, especially on long expeditions. The fit was perfect, accommodating my Kelty Zyp 48 along with a tent bag strapped below. The versatility in size coverage between 49-liter bags and 110-liter bags is something I appreciate, especially when my load varies from one adventure to the next.

One feature I find ingenious is the internal webbing loops. They effortlessly attached to my shoulder straps, providing that extra bit of security and protection. And oh, the cinching drawstring is a lifesaver, adjusting the cover to fit my ever-changing load.

The rain cover folds into a small bundle, fitting into its own storage stuff sack that’s conveniently attached to the inside of the cover – no chance of losing it. I love how it tucks away neatly, finding its space in the top pocket of my pack, adding an extra layer of protection over my electronics.

While I share the sentiments of some about wishing for a waterproofing coating, the cover held its own, keeping my belongings bone dry. It’s a minor trade-off for a rain cover that delivers on its promise at a reasonable price point.

On the fourth day of my Appalachian Trail expedition, the skies opened up with a vengeance. The rain was coming down in sheets, and I was miles away from any shelter. It was the real test for my Kelty Rain Cover. I hastily pulled it over my backpack, cinching the drawstring tight. The fit was snug, and the internal webbing loops attached securely to my shoulder straps, a feature I found to be incredibly thoughtful. As I trudged through the muddy trail, the rain cover stayed put, not budging an inch despite the gusty winds. Hours later, when I finally reached a shelter, I was soaked to the bone, but when I removed the Kelty Rain Cover, my gear was as dry as a bone – my sleeping bag, clothes, and most importantly, my electronics were all safe from the deluge. The quality and effectiveness of this rain cover not only saved my gear but also kept my spirits high in what could have been a morale-sapping situation. This personal experience cemented my trust in the Kelty Rain Cover, and it’s a story I share with every fellow outdoor enthusiast I meet.

The Kelty Backpack Rain Cover has now become a staple in my outdoor ventures, proving its worth with every drop it keeps at bay. Whether it’s a short weekend hike or an extended wilderness venture, I am now always equipped to face the unpredictable weather head-on, all thanks to Kelty.

Buyers Guide to Choosing the Best Waterproof Backpack Cover

Picking out the perfect waterproof backpack cover is a lot easier than you’d think. There are tons of options to choose from, but relatively few features and metrics to look at.


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.


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.


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.


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.


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.


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.
