Best Sleeping Bags For Wet (Rainy) Weather – My Top Picks!

When you’re camping in the backcountry weather can change on a dime.  One minute it’s nice and sunny, the next minute it’s raining cats and dogs and you’re rushing inside your tent. Staying warm during a rainy day means staying dry. For this blog, I’ll be taking a closer look at the best sleeping bags for rainy weather and what makes a sleeping bag great for those damp days on the trail!

The best sleeping bags for rainy weather are water-resistant, durable and easy to dry.  The best sleeping bag will vary from camper to camper, depending on the weather, where you are camping and your comfort needs.  In general, synthetic insulation tends to hold up better in rainy conditions.  However, down treated with a water-resistant coating will keep you dry as well, however, this insulation takes longer to dry.

Wet Weather Camping 101

Wet Weather Camping

You know camping in late fall is always a gamble when it comes to the weather. But, you have the itch to get out in the wild- to smell that fresh mountain air, to get away from it all.   With every step, you take up that long winding trail, the elevation changes- making weather patterns unpredictable and micro-climates a reality. The weather between one and two thousand feet can vary greatly and that’s why you have to be prepared for whatever Mother Nature throws your way.

If the rain starts to fall, it’s important to stay dry.  Water has a sneaky way of stealing body heat, dropping your core temperature and making you vulnerable and putting you at risk for hypothermia.  The most important thing you can do when camping in wet weather is to stay dry.  A high-quality tent will help keep a lot of that moisture away, but you also need to make sure your sleeping bag and other gear can handle a few raindrops or even a downpour.

Even if the rain stops, the moisture on the ground will be enough to get the bottom of your bag soaked.  A sleeping pad or tarp underneath your tent can help keep that moisture from transferring to your sleeping bag.  Again, staying dry will mean the difference between being comfortable and shivering and wondering if you will make it through the night.

Outer shell

Most high quality, well-made sleeping bag are made out of polyester or a durable nylon shell. Those materials most often are breathable, waterproof or treated with a durable water resistant (DWR) coating that keeps rain and snow from seeping into the bag and the insulation. You know your favorite raincoat? When the water hit the coat is beads up and it rolls off your arms. This is the same material used in the outer shell of most sleeping bags these days.

When shopping for a sleeping bag, make sure the label clearly states the type of material used in the outer shell of the bag. You’ll likely find more water-resistant bags than waterproof.  Water-resistant means the bag will stay relatively dry in light rain and drizzle. Waterproof bags are hard to come by right now. There are only one or two manufacturers in the world making 100% waterproof bags.  With that said, water-resistant coating on the bag is the most affordable and readily available option to keep the moisture from penetrating your sleeping bag.

Down vs Synthetic Insulation

When it comes to rain, synthetic insulation wins the gold medal- if keeping you warm was an Olympic sport that is. Synthetic insulation is made out of polyester- down like material, except its man-made.  Synthetic is warm and it holds up well in wet weather.  You can get a synthetic sleeping bag soaked and it will still retain its insulation value. The best part about synthetic insulation is that dries quickly as well.  So, if you tip over in a canoe, land face first in a creek with your pack or the weather suddenly changes, you know your synthetic insulated sleeping bag will be there to keep you warm when you are ready to call it a day.

If there’s even the slightest chance of wet weather on your adventure, opt for a synthetic filled sleeping bag. Plus, in most cases, synthetic sleeping bags are less expensive than down insulated bags.  In general, down is great for dry, cold weather. Down works wonders in sub-zero temperatures.  However, down loses its insulation value- i.e. doesn’t keep you warm, when it gets wet. That’s a big problem when you are 15 miles away from the nearest cabin and it starts pouring.

Recently, sleeping bag companies started treating down feathers and plume with a water-resistant coating to keep moisture away.  If you insist on going with a down sleeping bag, make sure the down is treated with a DWR finish. This finish will keep you warm even when it’s raining outside. Down sleeping bags tend to be more expensive, but they are the number one choice of extreme mountain climbers and arctic explorers.

The North Face Hyper Cat is a solid sleeping bag for those days when the clouds roll in.  The bag is made with a high-quality synthetic insulation to keep you warm, even when it’s wet outside.

Let’s talk about the insulation. This bag is made out of a Heatseeker one insulation, which is made with a Thermolite fiber. This state of the art material keeps the insulation light and allows it to trap heat to keep your body warm.  This insulation Is made to mimic down insulation, except it doesn’t get wet when it rains.  However, if the bag becomes fully submerged or it’s a torrential downpour, the bag will dry quickly so you can still comfortably sleep in it at night.
