I have 2 Fundles. I LOVE them!! I'm actually planning on getting another one for the summer
I have one in the Classic Black that I like, but the fabric is a little stiff. I also have the Supernova (denim) that I prefer because the fabric is softer & it has a little more give. I like the way the denim fabric drapes better & it seems more comfortable for the pup. They are both very sturdy with enough padding in bottom so that the bag keeps it's shape & keeps the pup safe. I have a small that works for my 3-pounder, but she also fits well in the standard sized one I have. The standard size fits my 7-pounders well, but I was thinking of getting a large so that they're a little more comfortable.
I highly recommend the Fundle.
It's an easy, casual bag that itsn't too fluffy. It's so comfortable to wear & I feel like my pups are comfortable inside of it. Plus, I can fit my wallet & iPhone one of the 4 pockets.
