what do you carry in your hydrapack?

Beer

Water, tools and first aid. Oh, and beer.

I like to keep mine as slim as possible but I ususally have:
Water or gatorade
phone
multi-tool
spare derailleur hanger
tube (for a quick-fix on my tubeless setup)
hand pump (no luck with CO2 in the past)
pins for Shimano chain

Beer, water, snacks, random other stuff...

Water
Pump
Spare tube
Multi tool
Cell ph
keys
and occasionally beer.

Just try and prepare for most of the common break downs like tube, chain and loose bolt. I always do water with a scoop of gatorade powder (just enough to tease you), multi tool, 2 tubes, pump (never do CO2!), sram gold link, food (PBJ's work the best since they are light and good energy), key's/cell/wallet because what the point in having a backpack if you have to carry stuff in your pockets still lol.

Good bits of info about the CO2! Hand pump it is...(wouldn't have thought about the spare derailleur hanger..good!)

Pre-fuel'd on vegetable juice and coconut water--drink TONS of water and eat whole fruits right before heading out

Pack dense foods such as almond butter (more nutritious than peanut), homemade hemp seed dried fruit trail mix concoction with pitted dates (save weight! ..ha) ...that's 100% rocket fuel!!!

Water
multi tool
FOSS tubes
..everything else has been covered

water, tubes, pump, tools, phone, some money, ID, chain links, first-aid kit, trail food, extra jersey

water
extra tubes
wrench set
extra shirt
cigarettes

Zip ties and gaffa tape

the mini allen key for the lock bolt for the gravity dropper cable on the thumb control

tubes,extra shit,wrench set,and oh water
