Recently ordered a complete set of transit pads and adaptors for a darien jacket and pants.
Happy with the pads- they are much slimmer than the TF3 pads which makes the outfit much less bulky to wear daily and more comfortable for touring. The back pad feels much more reassuring due to its larger surface area than the basic pad I had in earlier.
The TF3 pads seem to have more cushioning, but in an impact the transit pads are supposed to absorb impact better. Hope not to have to field test it. (Posted on 8/22/11)
