Which Hip Impact Pad?
I use the smaller TF 5 hip pads (8 1/2"h x 6 1/4"w), with optional sleeves in my Roadcrafter one piece. They are the easiest to manipulate my hand around to get into my pants pockets. (To reach a wallet or whatever.) And of the two versions of the larger size TF3 pads (9 3/4"h x 10"w), the curved ones with the hard shells fit and function a little better -- but the flat ones are by far the best-seller. As far as protecting your hips from impacts they're all roughly similar, with the curved hard shell and TF5 models being slightly better. So if you want bigger and better, go with the curved hard shell model. For optimum street-pant access, the TF5 model. And for effective lower-cost protection, it's the flat ones.
