what to put in a trail ride fanny pack?

I bought a fanny pack so I could carry my cell with me while on trail rides. (In the winter I have a pocket in my coat into which my android phone fits, but in the warmer weather I don't have a place to put it.) I have a little extra room in the pack and am considering what else I could/should put in there. Anybody have any suggestions? This is what mine looks like:

Pocket knife, hoof pick, bandaids, ibuprophen, small water .. all filled up!

Eta: Emergency contact info.

Like for if I'm knocked out and someone finds me and doesn't know who to call?

Sure .. or who your vet is .. if you take any meds, allergies, etc. Ya never know.

Check out Whinneywear this little pack is awesome! I didn't buy one but stumbled upon the list and this is what I take with plus my phone! WhinneyWear: Making you the envy of the barn

I like it just because it is PURPLE!!!

I bought a fanny pack with two water holders on it for our endurance training ride. LOL My buddies had gone out on a previous ride - went too far - were unsure of how to get back through the forest and were without water - so we LOADED up on the water to make this trip. I packed my fanny pack and took off...OMG it kept going under my butt. I couldn't get a good rhythm going with his jog because of that darn thing!!! LOL I finally got off, took it off and strapped it to my saddle.

Ok...back to you and your fanny pack. We put in Burt's Bee's for our lips, toilet paper roll, wipees, phone, keys, snack, small piece of rope, plastic bag to make a drinking bucket out of, small first aid kit.

We also had cantle and pommel bags so we had tons of stuff. My fanny pack is still in the trailer - I might have to get one like you have...purple makes everything better.

Purple DOES make everything better!

Yes it does. Biscuit's new saddle pad is purple, his bridle is purple, my water carrier thingie is purple, cantle bag is purple. LOL Heck, I might dye Biscuit purple!

Purple hay net .......
Buckets are purple .....

I am curious why you don't use a saddle bag attached to the horn or the back of your saddle, rather than a pack you put on your body? One concern I would have is if you have to make an emergency exit off the horse the pack can become another object on which you injure yourself.

Since it sits right at the kidneys falling onto it could really hurt. Not to mention having it bounce up and down on you at anything faster than a walk.

I guess it depends on the complexity and nature of your trails.... the ones we ride at are steep and rocky with loose dirt/rocks. The odds of coming off your horse are greater, even if the horse is deadbroke and solid mentally. The last ride we were on we came up new barbed wire fence and had to guide the horses over some boulders and a fallen tree to get to the other side. It was too dangerous (and narrow) to ride so we led the horses through it. I had limbs and vines on me. I could see a fanny pack as being an entanglement hazard.

But mostly, I don't like anything extra on my body when it is 100 + degrees outside.

I second the knife (but not one of those cutsey pocket things). Something that can hack through thorny ivy when it is wrapped around you and your horse.
