A lot on here relying on their phone, which is fine but you need a GPS backup if you lose or break it.
i disagree with the bluetooth speakers. Great for you, but annoy the shit out of everyone else, i could go on but wont give personal examples
I once took my Nikon camera and extra lenses with me on a 2 week trip, think i used it once!
It was too much hassle to get out, raining hard or didn't have it on me at the time i needed it, just quicker to get my phone out.
never again.
Maps and highlighters to mark out where I have been that day. Now have a nice collection of maps that bring back memories at a glance.
Use the GPS logs, they record even if your not following a route, you can download the log to your PC for ever.
they show exactly where you went, which is sometimes surprising, I had gone round in a big circle in Germany and didn't even know!

to be fair i think i followed a diversion and then improvised badly.
I take a laptop with me which i used for video editing, route planning and watching films etc
i dont take the official charger as its too bulky i used
THIS 100W USB C
Charger.
It charges my laptop through USB and also charges my phone super fast. its 100w but it senses the device you plug in so it will charge my phone at 45w from dead to full in about 35 mins.
I also have a
powerbank that gives 140w too that can charge my laptop and phones if there is no electric at camp that night.
it gets recharged on the bike during the day.
Agree with the
babywipes comments, useful for a number of things, getting bugs off your visor and headlight, wiping hands and face (and other bits) after wild camping etc (non scented

)
Garmin inReach
Although i don't have one, i would definitely purchase one or similar if going off the beaten track, it could quite literally save your life.
A thermal mug
Leaving camp in the morning, i make a coffee in my thermal mug which i can stop and sip at for my ride duration.
I do have a Camelbak pack with water but i nice hot brew in colder conditions is a real boost.
Heated gear.
if going somewhere cold it's a blessing, but a little bulky if you need to remove it so pack wisely.
Crocs
Yes i know some people hate them, but at camp there is nothing better than getting your big daft boots off and wearing something cooler (heat not looks

). They don't get wet and are easy to clean and are very light.
Headtorch
Less of a luxury and more of a necessity to be honest, I have the one built into a beanie hat
Audiobooks
If travelling alone, listening to the autobiography of someone you like is great while on the move makes a journey feel shorter.
You can play them from your phone either to your Sena/Cardo or in your tent at night with earbuds.
Airbed pump
blowing up an airbed everyday gets tedious, these pumps are tiny and get your bed up in seconds
MINE
Down Jacket
For wearing off the bike, light and pack really small.
Wireless charger
on the bike for the phone, so much easier and you always have a charged phone.
i also have USB chargers in my topbox for powerbanks etc
