Ultracrash pads seem to use the same gel technology that one sees with Silopad ankle protectors. D3O appears to be sterner stuff with typical applications being bullet proof vests for law enforcement officers, protective gear for moto-cross riders, etc. One of the drawbacks for male skaters attempting to use Ultracrash pads is that we generally don't wear tights and tights are important for holding the pads in place.
|Ultracrash pads must be correctly placed and once positioned must be held in place for maximum protection.|
|Female skaters rely on tights to keep the pads from moving.|
The D3O pads on the other hand are available both as separate pads like the Ultracrash products or sewn into a pair of shorts. Se_Ku lists men's extreme training shorts that have D3O pads sewn in to protect both sides of the hip trochanter region and a separate butt pad for protection of the coccyx..
