Bouldering climbing mat (Lewes, BN7)

I’m in need of a bouldering mat so I can start outdoors climbing, I don’t have many pennies to buy one and I desperately wanna start going to Harrison’s etc and climbing the boulders. If anyone has one they’re not using or even could lend me one I’d be eternally grateful! 🙏😁 thank you for taking the time to read this and I hope you have a lovely day. Mel
