I have a little 12-13lb dog that fits fine in the pouch when fully extended (zippers to allow pouch to expand). I am a 6'2" male, 170lb, lanky, I got the triple XL and the arms are just enough, little more length would have been nice but the sizing charts measurements are correct. and these are women's sizes as it states. Well put together, larger then usual draw strings, very soft material on the inside.Attention bunny moms/dad's: you need this hoodie!! Since bunnies are prey animals by nature, as I'm sure you know, they are easily frightened. I got this hoodie in hopes that it would help my bunnies feel safer and more secure when hanging around with me on the couch and it worked. I got the 2XL (I'm 5'8" about 200 lbs, dimensions are: chest is 38", waist is 29" and hips are 48") and it fits well/as expected. I got the large pocket as well. My bunnies weigh ~3lbs & ~4lbs (so just over 7lbs together) and they both fit in the large pocket easily. The pocket has a few different zippers to make it expand if neeeded, as well as a removable liner in the event someone has an accident. But you guy, I would buy this hoodie even if I didn't have a pet. The construction is impeccable, the material is excellent, it feels like it was constructed by a textile genius with a very unique gift. It's of the highest quality. The gray bands are thick and a nice addition, and the leather accents are very nice as well. I don't even like the color blue but I love this blue. I rarely endorse a product, but I feel compelled to help spread the word about this sweatshirt. I've worn it traveling to the Czech Republic as the pocket made access to my passport very easy as opposed to digging through my purse at the airport. I use the hoodie in place of a purse sometimes because the pocket holds everything I need. I got one for my grandma who uses a walker and doesn't have free use of her hands because of the walker. She's able to use the pocket for her necessities, and it's safe and easy for her. She had a history of falling at grocery stores due to imbalance and carrying various bags, etc. And this hoodie allows her to ditch the purse and keep her hands free to focus on balance. I wear this hoodie to class and use the pocket instead of a backpack. I know it's on the more expensive end of hoodies, but this thing is so durable and well made it'll last you your whole life and be the last hoodie you ever need to buy. Note to the person that created this Roodie: thank you. This is a truly unique product and it is exactly what I was looking for. I wish you luck, and please make this thing in more colors because I will buy every single one!!I purchased the pink in Medium (my normal size) and -- because my 7 lb. Yorkie is really a daddy's girl, and also because we also have a 9 lb. Shih-Poo who likes to go anywhere the Yorkie goes -- the Navy Blue in XXXL for my husband who is 6' and usually wears a men's XL (I would have purchased him a matching pink that but was not available in XXXL). On me, the Medium fits snug and if I buy again I would go a size larger because I sometimes have trouble raising my arms to get any kind of pullover on or off. Husband has no complaints, even the sleeves are the perfect length for him, not too long, not too short. It seems well constructed, and the material is very warm, so my main concern is going from outside to, for example, inside a store I would get too hot in this and would need to take it off, which defeats its purpose. Just wearing it around our chilly house for an hour heats me up and I have to take it off for a while. What would make this perfect for me is if there was a zipper in front, if only halfway down to the point where the pouch starts, to aid in temperature control.I like that my cat enjoyed it and took a nice cat nap in it.The only thing that sucks is I like to wear baggy jackets or sweaters and decided to get the 4XL and it fitted as a medium/large which would be an exact fitted wear for me and not baggy whatsoever. So if you actually wear 4XL I’d say beware bc it might not fit you at all :/I weigh 90 lbs, 5’3”. Typically I wear an xxs, but the xs fits perfectly (the xxs sleeves would have been too short). The sweater is very comfortable and it can fit my Chihuahua and a 4 lb Toy Fox Terrier. I haven’t washed it yet, but the instructions make it pretty clear to NOT put it in the dryer to prevent shrinking. Worth the price.I updated my review from 4 to 5 stars because after 2 weeks I figured out the hidden pockets!!! :)My dog is 11lbs and fits perfectly, he loves being walked around in this thing. The quality is amazing, I’d compare it with an underarmour hoodie, super soft and thick material. The pocket is lined so you can remove and wash it! The only down side is that it seems a bit pricey but it’s a great idea and I received it as a Christmas gift, so me and my pup Max love it!Got this for my bf so he can carry his 7lb chihuahua around as she’s getting older. First one I got was a med and since it’s cut for women it was too small I got him a large an xl and that fit better.he’s not a big guy by any means. Order one or two sizes up. The pocket doesn’t get any bigger and neither do the sleeves which I thought was weird. They’re oddly tight circumference wise. Hope my review helps!I had got this as a gift for my sister for Christmas. It is very good for her guinea pig. She has worn it nearly everyday and her guinea pig appears to love it. You must buy it one size up though. She would normally measure as a medium, but the large is a perfect fit. We have not washed it yet, but as long as it does not shrink, this will be a gift that will last quite a few years.
