Why aren't all wetsuits made from the thickest materials?

Not all wetsuits are made from the thickest materials because different water temperatures and activities require varying levels of insulation and flexibility. Thicker materials provide more warmth but can restrict movement, making them less suitable for high-intensity sports like Surfing or diving where flexibility is crucial. Additionally, thicker wetsuits can be bulkier and heavier, making them less comfortable for extended wear. Manufacturers design wetsuits with a balance of thickness and flexibility to cater to specific conditions and activities.
