In a real emergency you probably wont stop to put on rubber gloves. Having said that, if they are wrapped up tight they will take up very little space. I like keeping a small bottle of saline rinse in my trauma kit, because depending on whether theres gushing blood or not, I may wish to irrigate the wound before wrapping it. As for bags I like the red Maxpedition pack.

OK, so, they used to offer the FR-1 or something similar in Red. I cant find it now.
