What is the difference between the Amphibian and the A-Suit?
The cut of the Amphibian and A-Suit are identical. The differences are in the fabrics used (the Amphibian is made from a unique woven tissue while the A-Suit is made from a knitted lycra), and that the Amphibian does not have a chamois (padding for the bike) while the A-Suit does. Refer to the information pages on each model, and the Tissue Talk page in the Customer Services menu for more detail.
