The only info I can share with you, is that I bought this a couple of years ago and had to return it. I must have ordered a size small. I wear a 32D, so I'm a pretty small person. They sent me what I would guess was a child's small because I could barely get my second arm in it and there was no way it was ever going to snap in the front. I believe I got free return shipping since Amazon is pretty cool about taking responsibility for any mistakes in the way things are posted on their website. It appears they now have the sizes listed, rather than small, med, and large. If I were you, I would order the size you would normally wear in a top and then if it's not right, return it. Wish I could be more help! The only info I can share with you, is that I bought this a couple of years ago and had to return it. I must have ordered a size small.

My dog is 100lb American Bulldog and I had the same concerns of inbetween the large and medium. I went with the medium and it fits great. So I would choose the smaller of the two sizes your looking at.

I think in that case, it would go by your age... Which I think is before or after 30. But if you contact the company, they would likely be able to tell you for certain. You could probably also ask your doc, could give you a better idea of what size you'd require personally. Cheers!

This will definitely work for you. My boy is 48in and about 44 pounds. And we spend a week in NY and that was all I used.

this will work for the size you need. I have an 80 lb boxer and 12lb chi, they both use it and are fine! My boxer is 10, so she goes through it slower, but she fits fine.

Large will be plenty big enough. My lab is almost 100 lbs and the large is perfect for him.

Im size 6 and its fine. But size 4 is quite smaller. It would probably still work, but would also be quite bulky.

We had three plus an 80lb dog, which was no problem. 4 would be comfortable six would be tight

I used 5 & 8 lbs but I'm a weakling. Try around 10 lbs to start with if you are fit already.

I wouldn't purchase this for a ten year old unless he has a very slight build. I would say this fits sizes 4-8.

I think they offer different sizes, but perhaps the reviews attach to each model. I'd trust the listing and order the size you need.

I'm 176 and 70kg, I also have 100cm of chest.I bought the size M and it was perfect.I think the fact that you're thin you will also use the size M, because what makes a difference is the width of the chest.

Yes, it does say up to 100lbs. But you should contact the seller since I never heard of that bag. Lol. I don't want to give you the wrong information. You're going to love it, I'll tell you that. : )

I have about the same measurements as you about 120-123 lbs and the small fits just right. You could even put it really tight if you wanted to. Hope this helps.

I have a goldendoodle who weighs 98 lbs and I got the XL. It is pretty big on her and I have been thinking about getting another one in the large size. I think you would probably only need a large.

I would say 6 or 8. I think we have to go up a size from our Reg clothes to fit good. I did that and it ended up working for me..at first I went up 2 sizes and ended up being to big.. so for sure I think u should get a 6. hope this helps.

I did see sizes. May have to look "Paws Aboard" life vest on Google. There is XS, S, M, L, in this type. We have a 13 pound Bichon and the small was perfect for him. See their site. They give sizes in regards to poundage of dog. http://www.pawsaboard.com/pages/pet-life-jackets/
