I've had only plastic carriers in the past, so this is a new one fir me. It opens in both sides and has mesh "windows" on top of the flaps as well as on top of the carrier, so you can clearly see what your pet is up to and comfort if in need. There are small pockets on necessities and on one of the sides there is additional opening. The bottom of the carrier is lined with fleece which is stuck by velcro, so removable and washable (carrier is washable too according to instructions), but being able to remove fleecy bottom Is an added bonus. I always had to line carrier with blanket before, so happy now I won't need to do that and my kitty won't slip around and will be comfortable.
There are also two types of handles- either short ones or one long strap- whatever someone's preferences. I always like to check on my cat while out, so short ones suit me better, however it's good to have different options.
I've only used it once, and had no typical resistance from my cat while encouraging her to go inside( could be curiousity though). It's more comfortable to carry than plastic carriers and I enjoyed all round view of her. It seems to be good for current weather, not sure how it holds if it rains. It's sturdy enough while walking, so keeps the shape and my cat seemed to be less stressed than normally. When I came back home and left it open, she went inside, so it was clearly enjoyable experience for her.
