Most of the brands listed below offer wetsuits for a variety of conditions including winter and cold water. General Paddle Clothing Options
Most wetsuits (neoprene, Yulex and other natural rubbers) are designed by their branding company but manufactured by one Taiwan-based company - Sheico (manufacturing facilities in Taiwan, Mainland China, Vietnam, Thailand and Cambodia). Sheico broke the expensive monopoly Japanese neoprene manufacturers long maintained and they have been the innovators behind a number of improvements in materials for wetsuits. Some brands like Rip Curl have their own factory but get their neoprene from Sheico. Yamamoto pioneered limestone based neoprene and until 2020 they were the only maker of calcium carbonate derived neoprene (See Sooruz “Oysterprene”). Sheico does make wetsuits that use limestone based neoprene. There are different grades of Yamamoto limestone neoprene and some companies report which they use but you will have to call many of these companies if you want find out which grade their suits use (or if their customer support knows).
The following brand list does not include a lot of smaller, locally owned and mostly only locally known, wetsuit makers. You can sometimes find such companies when you visit locales where wetsuit use is common. Locals wearing locally produced wetsuits will probably be the best reviewers you can get for such suits. And these local suits can be high quality and not overly expensive compared to similar wetsuits from larger companies with larger overhead from advertising, etc. Local companies that make their gear at their stores sometimes also offer convenient custom fitting options for walk-in customers.
Some of the listings below show countries where companies originated, but many of the bigger companies are truly multinational now.
