      No news

      Hi, I sent an email inquiring to change the size of the bag and still didn’t hear from you. Please reach out asap

      Basically as advertised, but cheap quality

      No waist strap.
      Chest strap detaches with any amount of tug to tighten, has to be painstakingly reattached.
      Straps are skinny, not much padding, like a $15 walmart backpack.
      The customizations for dogs are nice, but for the price I expected a higher overall quality, dissapointed.

      Great bag, I bought it for fourwheeling. (ATV)
      And it is a success. I use it for a Boston terrier 20 lbs.

      Great pack!

      This is a well made, well designed pack for our little shorty Jack Russell. The sizing was perfect, following the sizing guidelines provided. We followed the training guidelines and were amazed at how quickly he adapted to being in the pack. He actually seems to like being in the pack and looks quite comfortable in it. He gets tired on longer walks because of his short little legs, so this is perfect for him. Now we can take him on longer hikes. Love the fact that there is the extra pack that can be attached for taking his water and gear. Great product! We received the pack in under a week after ordering.
