Yoga Mat Selection - Help

Hello,

I’ve been practicing yoga for years & years (indoors, on carpet and hardwood). I’ve never used a yoga mat. I’m thinking of moving my practice outdoors this spring, and I’m considering the purchase of my first yoga mat, mainly to keep me & my clothes out of the dirt and grime.

Questions:

1 - Should I even bother with a mat after all these years without one?

2 - Would a wider/longer mat really make any noticeable difference for a larger person?

Thanks

Please help

I didn't find the right solution from the Internet
