In the past we have recommended wearing long sleeve shirts and long pants underneath Aerostich suits. We still do, but after seeing thousands of crash-damaged suits, I'm more relaxed about wearing shorts and a t-shirt underneath. Especially for casual riding, touring, and traveling. There are trade-offs but wearing shorts under Aerostich suits can make warm weather rides a lot more comfortable. The shorts can be cotton, synthetic or blended fabrics. Shorts are also great at any roadside stops or destinations after your suit is off. Combined with tall riding boots they make an attractively hip look, right?
