The shirts are in soft cotton, a bit on the thin side but very comfortable to wear. Designs are in monocolor black with a vintage feel. They are handsome and understated. A postcard of the National Park is included in the package. It was a gift to my husband, notoriously difficult to gift and a Park lover, and he wore his instantly. So far, we have received Denali and Smoky Mountains, and he is anticipating his third shirt eagerly. Great gift for outdoor lovers.

Updated Review - LOVE THIS BOX!!!! My initial review showed my confusion on how to do find the password and play along. I messaged Parabox and they provided me with hints on how to solve the puzzle. I am 4 boxes in and just got notified that my 5th box has shipped. I really love the challenge of this! I actually wish they would add a few more things to find and delve in a little deeper. The t-shirts are good quality and have creative designs on them. If you make it through the puzzle you get registered for a monthly drawing. I won one and was impressed with my prizes! Really nice hooded sweatshirt, hat, stickers and more. Definitely renewing for another 6 months.
Initial Review - First time ever getting a box subscription. I got the shirt and an info card. There is supposed to be a hidden password but don’t really know what I am supposed to be looking for. Since it is a new box and this is the first one they are sending out to anyone I thought it might provide some insight and background on how to play along.
