A lot depends on your individual preferences, however, here are some basics you should consider:
PADDLE - The club supplies paddles to new paddlers.
DRINK - Paddlers should bring a small bottle of water or sports drink to carry with them in the boat.
CHANGE OF CLOTHES - A change of clothes and a towel are recommended
NEOPRENE - You'll see a lot of paddlers wearing neoprene (wet suit material) shorts. Neoprene is popular with paddlers because it minimizes chafing. Biking shorts work as well.
FOOTWEAR - All paddlers must help put boats in the water and bring them out. Early season, wetsuit booties, rubber boots, or running shoes and wool socks are recommended. Flip flops or sandles are good for warm weather.
GLOVES - Sealskin, waterproof, sports gloves or rubber for early season. Biking gloves for later season.
