Hello Folk, As cooler weather approaches there has been a lot of discussion about how to dress for the cold.
Really there are two different types of cold to consider.  Air temperature is very important because we will be dealing with that for sure but most people have no problem dressing for cold weather.  Water temperature is a different animal all together.  Even when the air is warm, if the water is cold enough we dress for the water and just deal with high body heat while paddling. When both the air and the water are cold, then it can become life threatening not to take clothing seriously.  If you are chilly while dry then it can turn into a very serious problem when you are wet. Always remember, the best paddlers in the world still have spills and get wet.  All us boaters are simply swimmers between swims.  With that in mind I hope the following information is helpful to you. Read to the end and I will give some links to where you can buy the appropriate clothing.

Since our group is for new paddlers I know that most of you do not have the clothing to paddle when it is cold. When I first started that was one of the biggest problems I faced, how to dress. Even when it gets warm, the water is sometimes very cold so clothing is always important.

Year round paddling offers many advantages over just paddling during warm weather. I am taking the liberty of sending this article that was published on the NRS website. I think it is good reading, even for those of us who already paddle year round. I hope you all get something from this.

For more articles on paddling, and also to find more information on this subject, visit

NRS is more than just a place to buy paddling equipment, they also have a lot of good information for free. 

Paddle safe, but paddle something.

Layering for Cold Water Boating 


Year-round boating is the ideal for many of us. For most areas of the country, this means we will be boating at least part of the year in cold-water conditions. Boating is a water sport – let’s face it, getting wet happens and water is approximately 25-times more efficient than air at drawing heat away from your body. This means once you get wet, your body is more prone to excessive heat loss. This condition, known as hypothermia, causes more cold-water boating deaths each year than drowning. Check out Cold Water Protection & Hypothermia for more information on the effects of cold water heat loss. 

The key to protecting yourself from that heat loss is the simple concept of wearing multiple layers that will retain your body heat when you get wet. Layering lets you add or remove pieces as the day’s conditions change, helping your body maintain a safe, comfortable temperature. Typically there are three main components of an efficient layering system – the base layers, insulating layers and the outer layers. 

The Base Layer 
Start with a moisture-wicking layer next to the skin. Synthetic fabrics such as polyester, nylon and polypropylene don’t absorb water and move moisture from your skin to outer layers. Merino wool wicks moisture and is comfortable against the skin, unlike traditional wool. Do not wear cotton, it's comfortable when dry but absorbs water and dries slowly, losing its insulating value when wet. Check out our line of NRS Base Layer apparel, notably the NRS HydroSilk Rash Guard, NRS Wavelite and Ibex Merino. 

Insulating Layers 
Over the base layer you want one or more garments to hold in your body heat. These can be synthetic or wool fabric pieces of varying weight and thickness or a neoprene garment, or any combination of these pieces. The synthetic and wool fabrics are breathable, light-weight, and afford good freedom of movement. The synthetic fibers won’t absorb moisture, but rather allow the water to radiate away from your body, keeping you more comfortable as you generate heat while paddling. Merino wool, on the other hand, absorbs up to 30% of its weight in water while still maintaining its insulating value. This characteristic of wool helps it keep you warm when conditions are cold and cool when it’s warm. Check out the range of insulating layering options in the Base Layer section of

Another consideration for wool is that it’s a natural fiber that is renewable. Merino has the advantage over traditional wool of being a very fine fiber that does not prickle or itch when worn against the skin. And, it doesn’t hold odor, no stink! Any of the Ibex wool garments found in the Base Layer section can work well in your layering system. 

Neoprene is a closed cell rubber material that is an excellent insulator. It also offers impact protection as well as extra body flotation. Thicker neoprene will be warmer but more restrictive to your body movements. If warmth is your main concern, you’ll be well covered in our NRS Men’s and Women’s wetsuits . Thinner neoprene will stretch much more easily, but won’t be quite as warm. If your priority is mobility, check out our NRS HydroSkin, a line of thin (0.5-mm) neoprene garments that give considerable warmth with the comfort and mobility of thinner layers. All NRS neoprene garments are made with a glue layer between the inner nylon fabric and the neoprene foam that contains tiny particles of titanium metal. These shiny metal particles reflect back your body’s heat and significantly increase warmth. 

Outer Layer Wind and waterproof outer garments rounds out your body core protection system. An outer layer made with a fabric featuring a breathable coating or laminate is definitely preferable. This will allow perspiration moisture to pass out of the garment, keeping the inner layers drier and significantly increasing your comfort and warmth levels. 

Outer layers come in many shapes and sizes, but there are three main types: splash wear, dry wear and semi-dry wear. Splash wear is simply any waterproof outer layer that is designed to keep your under layers dry if you get splashed or rained on. If you’re using neoprene as your insulation layer, wearing a waterproof garment over it will cut down on evaporative cooling from the wet outer fabric of the wetsuit. If you go for a swim in splash wear, your inner layers will get wet. 

To keep water out during immersion, you need dry wear garments that have latex gaskets at the openings. Drysuits are the ultimate option for immersion protection. With their waterproof zippers and gaskets at the neck, wrist and ankles, they’ll keep water out of your inner layers. A number of our drysuits now come with waterproof, breathable socks. A dry top and dry pant combination may leak a very small amount at the waist juncture due to torso movement, but you’ll stay dry enough to be safe during a swim. (I currently have dry pants and a dry top, they work well for the rivers I paddle but a full drysuit is on my wish list, John)

Semi-dry wear splits the difference between the other two styles. There are semi-dry tops and some semi-dry suits on the market. Typically, they will feature latex gaskets at the wrists (and ankles, on a suit) only. The neck usually features a punch through neoprene “gasket” or an adjustable neoprene cuff of some sort. Semi-dry wear is a great option for touring and recreational kayakers and rafters, who want to prevent water entering their inner layers at the wrist and ankle and don’t need quite such a water-tight seal at the neck. 

Don’t Forget the Extremities 
You lose a lot of heat from your head. Caps or helmet liners made of neoprene or synthetic fibers can really keep you warmer. Footwear and gloves for boating are generally made with neoprene as the insulating material. If you find your fingers and toes getting really cold at times, a helmet liner will help cure this as much as gloves and booties will. Keeping your head warm creates a chain reaction that you’ll notice all the way through your body. Additionally, gloves and boots provide increased grip and traction while they insulate. You can add neoprene socks and glove liners for even more protection from the cold. 

Questions to ask yourself before boating on cold water:

How cold will the water and air temperatures be?
In the past, how comfortable have you been at those temperatures?
What’s the weather forecast?
How experienced are your boating companions?
How reliable are your self-rescue skills?
How easily can you get to land to warm up and change to dry clothing, if need be?

Things to consider when boating on cold water:
You’re engaging in a water sport – exposure to water is going to occur.
Dress for the worst-case scenario you may face, usually a long swim.
Have apparel that you can layer together to adjust to changing conditions
Don’t forget your PFD. It acts as an insulating layer and will keep you afloat while you’re recovering from a swim.
Practice self-rescue techniques.
Test your cold weather apparel by taking a dip in it.
Check with local boaters, boating clubs and search and rescue organizations for gear recommendations.
Bring high-energy snacks and lots of liquids. A thermos of something hot is good to have along.
Remember – going out boating is optional, coming back safely from a trip Is MANDATORY! I buy as much of my gear as I can from The Outside World in Dawsonville.  They do price matching, they will not be undersold, they will ship to you and they are local, SUPPORT OUR LOCAL BUSINESSES!!! And don't forget the discount they will give you just for the asking. With that said, about the best place I have found to buy thermal underwear, especially polypropolyene, is at I hope you find this helpful, I hope to paddle with you all in the coming months.  Watch the schedule for fun chilly paddle trips.
