Swimming for the most part is a fairly cheap sport to partake in. A cheap jammer can cost as little as $10 and goggles cost as low as $3 but I wouldn't recommend going cheap if you swim to win. Swimming is a sport where you are constantly fighting drag, whether it is air resistance off the blocks or the water while swimming. Up until sectionals, we all use the suits the school is willing to pay to get us, and there ok. Then when sectionals rolls around in February, you see very few school suit and you get to look around at the different tech suits that people were willing to pay for. This past year I bought a pink, Arena Carbon Air tech suit for $250. This suit is thin and made of nylon, elastane, and carbon fiber, resists the water and cuts back on drag. This is the suit I liked but many others had a Speedo Fastskin. This suit is designed to cut down on drag forces on the swimmer and has attempted to mimic shark skin. the suit has small v shaped ridges to reduce the drag at the swimmers body. These ridges disturb the stagnant water trapped by the swimmers body decreasing drag. Between, the suits and shaving, swimmers can become quicker, and more competitive at sectionals. This is why I invested.
