SMS coveralls are made from a strong, three-layer material that helps protect you from light splashes and sprays. Even with this protection, the coveralls are designed to stay breathable so you can stay cooler for longer.
The outer layer gives the suit its strength, while the middle layer helps block liquids. This middle layer also lets air pass through, making the coveralls more comfortable and reducing heat buildup.
A storm flap covers the zipper to keep liquids and contaminants from getting in. The attached hood helps protect your neck and shoulders, and the elastic wrists and ankles keep the sleeves and pant legs securely in place to prevent skin exposure.
