DYI Tracking Pants
I've been looking around for a decent pair of pants that I could convert into some tracking pants with minimal modifications. I found these which look almost perfect!

The way the pockets are done, you'd need to cut the pocket out and undo the zipper. Now, the cool thing is, if you keep the zipper on there you could probably just zip them up when doing a normal jump.
Also has the internal adjustable leg gaiter, and adjustable waist.
The only real thing you'd have to modify is to add an extra vent or two somewhere down the leg for faster inflation.
Just thought I'd share.
