Just got a mountain bike! Now what?

So... what's a gillet and a couple of buffs?

I call it a gillet - you'll call it a vest! A buff is, well a buff:

I use one under my helmet when cold and sometimes one as a "scarf" round my neck to keep the wind out. Absolutely fantastic things, I use it for running to keep my hair out of my face, hiking, climbing,....

I forgot to say I carry lots of food because I prefer to eat than use energy drink (unless its a multi day event or something).
