They too are made of vinyl although it is a bit more sturdier than the 97s. That being said, all vinyl helmets are prone to warping if not stored properly. Cool, dark place and avoid leaving them in direct sunlight (like inside of a car on a hot day).
The 95 DPs came in two different forms; a white interior (the sturdiest of the bunch) and a green interior. The 96 only came in green. The white 95s are a bit harder to find as they were the first batch, but a good choice if you plan on sticking with a vinyl helmet.
