Wetsuit Thickness Explained
4/3mm = 4mm in chest and legs and 3mm in arms.
5/4/3mm = 5mm in chest; 4mm in legs; 3mm in arms.
5/4mm = 5mm chest and 4mm arms and legs. These are often too stiff in the shoulders for paddling.
5/3mm = 5mm in chest and legs, 3mm in arms.
Wetsuits for Different Conditions and Temps
Neoprene Top and Bottom (2 pc) – Ideal for flat water paddling, minimal waves and wind, temps above 50F. Recommended brands, NRS and Vaikobi.
Farmer John/Jane Armless Wetsuit – By itself or with an added neoprene jacket or nylon splash top and insulation, use for above conditions or slightly colder if you run warm. Popular with kayakers, schools/rentals.
Shorty Wetsuit – Armless and legless wetsuit. For slightly chilly temps.
Spring Suit – Usually a 3/2mm or similar thinner suit for slightly chilled temps. Some have no sleeves.
Full Wetsuit – Usually 4/3mm – 6mm fully enclosed suit with or without a hood. For 60F water and less. $150 – $600. Many good wetsuits are actually dry and seam sealed and now not wet at all.
Dry Suit – Non-neoprene, usually nylon or GoreTex full suit that goes over chosen interior insulation. Water kept out of neck, wrists and some feet with latex or neoprene gaskets. Popular with kayakers and has a pee zip. Costs $400-$1,600. Brands: Koktatat, NRS, Stohlquist, SUP Skin and Ocean Rodeo.
Dry suit vs Wetsuit?
Dry suits only keep you warm from the insulation you add underneath and being dry. They’re not always dry and sweating is a factor. Many
look and feel baggy, though the Ocean Rodeo Soul is the first cool looking dry suit.
I switched from dry suits to wetsuits as with SUP I swim more than I did with kayaking and found wetsuits are better for this whereas drysuits were harder to swim in.
Dry suits do have maintenance to keep latex gaskets in shape or if they tear on a trip, they’re difficult to fix.
Dry suits range from $400-$1,200 and wetsuits range from $125-$650.
Cons of a full wetsuit? No pee zipper. But I rarely have to pee in my suit. On hot flat SUP days full suits aren’t very comfortable to paddle in even if pulled down to your waist. In super cold wind chill (10F-20F) wind chill can get through the neoprene.
Full Suit Zipper vs Top Entry?
Full Wetsuit Designs:
Hooded with chest zip (enter from the top, throw hooded flap over head and secure with chest zip)
Back Zip (no hood) – Get one with a ‘dam’ which prevents from feeling water leaked in from the zipper.
No Back Zip (no hood) – top entry, usually a non hooded flap that goes over head and zips on at chest
Top Entry / No Back Zip: Top entry suits are drier as they don’t have a leaky back-zip. Some top entry suits have a zip-off shoulder area and either a zip of or attached hood. Lots of options for top entries.
* The downside to top entry is that they can be hard to get into especially if you have sore, lack of flexibility or injured shoulders. Add a rash
guard top underneath to help in slipping on/off the suit.
My favorite Fall – Winter suit for several years now is the top-entry hooded, seam sealed and fleece lined RipCurl FlashBomb 5/4mm.
Back Zip: These are easier to try, get into and peel off easier. Zippers can leak so get a ‘dam’ which is an attached neoprene flap that goes in between your back and the zipper to keep water out.
I like and use the RipCurl Dawn Patrol 4/3mm which has the dam and some of the fleecy FlashBomb material in the chest / back areas.
Attached Hood or Not?
If you paddle or surf in cold water, a hood will keep the water from flushing down your neck, even if pushed off around your neck. In super cold water you’ll get pretty cold without a hood.
Detachable hood options are good or a separate hood (pictured) if you’re not sure about temps.
Life of a Wetsuit
I’m not good with taking care of things and I paddle often in saltwater. So my suits are in their best condition for only a year. Friends who paddle only on weekends and/or only a few times a month or seasonally can have suits last for a few years or longer. First things to go are the seams. I also get neoprene tears which create leaks.
Increase the life of your suit and prevent smelly neoprene with regular cleaning in soap and fresh water which will greatly increase the life of your suit. See my post on wetsuit cleaning “Stop the Stink.”
You can fix your own with various neoprene glues but I send my rental suits in bunch after my working season to ProMotion Hood River, Oregon. They’re cheap, do an amazing job and have very quick turn a round.
Brands are saturating the marketplace with terms such as sustainable, green and organic. If you’re worried about all this rubber
being in the environment, worry no more. Most brands now boast about limestone or charcoal neoprene and the like. Patagonia’s suits are described as “the post consumer recycled polyester jersey increases durability while minimizing environmental impact..” TreeHugger has a good article on the subject of green wetsuits, Here.
Popular Wetsuit Brand that I Recommend
Layering Clothing on Top
Add warmth to your wetsuit especially if you have a 3/2mm or 4/3mm by adding a non-cotton rash guard or similar thermal top (no collar). Adding a Splash Jacket or hooded vest (photo) over the suit can really help cut wind chill and keep in warmth.
Paddling jackets also help too. I’ve been using jackets from NRS and Season5.
Neoprene shorts can help boost heat under your suit. And helpful for sit on top kayakers and surf skiers with bucket seats.
Hooded Vests like the Patagonia Yulex Water Heater Hooded Vest can go over your wetsuit giving you a toasty hood and will keep water out. Or it can be worn alone in warmer seasons or waters.
Try before you buy. I just had a student return a suit which didn’t fit which he bought online. Everyone’s body is different so what works for one may not fit for another.
Neoprene tends to run small. I wear a XL shirt but have to wear a XXL suit. Same goes with booties. Check suit reviews if the size chart isn’t clear.
Wash regularly. I wash mine every other use. Soak in very hot or cold water with a non detergent soap or wetsuit soap from Dawn or GearAid. Rinse and hang dry. I have a floor heater to bake my basement bathroom. Dry inside out, then the outside. See my blog post on cleaning and drying wetsuits.
