Surfing waves of flowing rivers is becoming more and more popular. With regards to equipment it is important to consider the conditions of those river waves accordingly.
Since you’re spending most of the time outside the water on the fresh air you have to take into consideration the outside temperature as well when buying a neoprene suit. Wetsuits with a rubber insert on the chest protect you against cold winds when outside the water. Since you’re mostly confronted with unknown river beds whilst surfing and you’re probably walking a lot next to the river back to the entry point, Booties are a very useful addition to your suit. They keep your feet warm and offer extra protection. Hoods and Gloves make sense, too. This way you can ride those waves year-round.
