How big are your pants exactly? This must be your first concert huh? Your pocket really will be fine. It's not going to jump out onto the floor. If you're really that worried, leave it in the car, or don't bring it at all.
hahaha it's summer so I mostly wear loose-ish shorts. But I wanna take photo's and videos aswell as mosh.
ehhh, might just give it to my friend and get him to wear jeans haha.
