I have the black epi right now and use that as my every day bag (inside of a larger laptop bag). I love it to pieces but I'm worried about the abuse its taking. It looks amazing considering the daily abuse over two years but I'd like to take it easy or it or have a backup. So: Mono or red Epi???? I've been wanting the red epi for a while but I think the Mono would be more durable. But its EVERYWHERE (or a knockoff is anyway) around here. I like that its a tad bigger but I've been use the thinner epi for a while now and I'm fine with it. Thoughts???
