So, after searching around, I found three possibilities.
The first is a set of unknown brand (I know it started with a G lol) from our local Cal Ranch store. It's a 3-in-1 combo bag in red for $39.99. I took a picture of it while I was at the store, for reference.
The second set I found while searching online. They're insulated, with twelve pockets, two water bottle holders (with water bottles) and are made from cordura. They only come in black or brown (would get black), though, but I could always sew patches or something onto them to make them look more "fun." However, they're $29, so they'd cost about the same as the Cal Ranch set once shipped.

Then there's the splurge set. They were recommended by the trainer at our barn when I asked her opinion. She has a set and loves them. She quoted the "You get what you pay for adage" to me when she recommended them. I like them and I know they're tough (I've checked hers out before), but they're a bit more than I really wanted to spend right now. However, they do come in red. They're $55.50 plus shipping.
So, knowing that I do only light to moderate trail-riding, maybe one day a week, I ride in an Aussie saddle (has five D-rings plus the crupper ring on the back) and love red (), which set would you go for?
