The Better L.L Bean Bag

Rating: 5 out of 5 stars

My fiancé threw up in my customized L.L Bean bag when we first began dating.
I can no longer get the bag anymore as the company does not do the same customizable bag.

I told him that I want a better bag and found this company via my job (EMS). He got me the bag 2 years after ruining my last one.

I will NEVER let him even touch this bag. The zippers are satisfying. I fill it to the brim with stuff for my shift or for drill. Even school stuff. The padding and support is amazing. Meal Prep containers and an ice pack was just the cherry on top.

Overall, I highly recommend this bag. I would get it again in a heartbeat.
