First of all, there's the basic climbing bag, but also the rope bag. This one can hold quite a bit of gear too, because as you'll see, the list is long... let's go!
3 pairs of shoes: there's the good, brand new pair, the "you never know" pair, then the good pair for putting on The Test! And finally the bad pair (with holes) for warming up and working climbs.
Then there's all the essential safety stuff: the harness, the rope, the grigri, the quickdraws, the helmet (if there's a risk of rock fall). I think everyone knows this, so let's move on.
Warming up, it is important to be well warmed up before going into the project,
I always warm up on the floor before I try. We start with the elastic (joints, mobility, muscle awakening), then we move on to serious things, the beam, to warm up the large muscles, the fingers, and do a little specific to the route attempted.
To optimize climbing conditions I have a powder bag of course, from time to time a knee pad, then a spare powder bag, important to put as little powder as possible in the climbing bag (to gain comfort), a brush, and there we go.
For comfort! This is important because we spend a lot of time on the ground, so you need to bring shorts in case it's hot, and also pants for when the cliff is in the shade. To combat the cold, I always wear under gloves, and if that's not enough, I also have ski gloves! And if we reach really low temperatures, I have the small hand warmer, very pleasant in the bag to pof during the climb (I recommend)… a neck warmer and a hat are not too much to climb warm! Then the basic things, a down jacket, sweater, jacket…
And then the rest! I call it the rest but without it my days at the crag would not be the same! I start with my pink crocs, comfortable, coming down from my route nothing better than not wasting 15s putting your laces back on, hop the crocs, fast, efficient, and so pretty… A little cushion for the back, a little mat for the buttocks, gloves for belaying (we keep our hands warm and we don't get them dirty), a knife (very important), to cut the rope when it starts to get damaged, to spread the cheese, and so on, strap for friends and me, in case of a little bleeding, or to avoid the pulley! A lighter to make a little fire (don't overdo it), a headlamp, especially in winter when it gets dark early, a little phone case, at least it's warm, you don't lose it and it's less likely to break! I always have a thermometer, it amuses me to set records, last time a little run at 6 degrees hehe! And it's good to be precisely aware of your environment!
A bottle of water with something to nibble on! Money to buy a little appetite suppressant at the bakery or the butcher (pizza, sandwich, chicken and potato, etc.), I often have a weighted vest for my first climbs, it's my method :)... toilet paper for... in case of emergency, and for friends too... forget the speaker, otherwise at your own risk...
The list is long, but generally everything fits. I also bring a shopping bag to avoid having a bag full of things that scatter as soon as you open it... It's quite practical...
The bag also varies depending on the cliff, if you go to Ceuse you don't need to plan as much otherwise goodbye to your thighs and back, and also depending on the season (winter, summer).
