I got a large for my 54 pound boxer mix and it fits her perfectly. It's helped her not be afraid to go in the water.

Nicely made and strong but much larger than expected, xl too big for my Pitbull mastiff with 22 in neck measurement, disappointing

Seems like a very well made gi. Chose this one because it claims to be preshrunk, and is lightweight. Have not used it in practice yet. Just started lessons. This company's sizing seems almost one size larger than their competitor's sizes. The other people in the class were surprised I had to get an A2. I am 5'11" and 187lbs. The last dress shirt I bought was 16.5" neck 34/35 sleeve and this A2 fits perfectly. I bought the A3 first and it was enormous.

The XL Fits my 56 pound pitbull female, little tight in the chest which is perfect since she squirrels out of stuff. Hood also doesn't flop into her face.

This is comfortable but it runs large. I bought a medium & it is huge, it fits my boyfriend who is a xlarge

Ordered wrong size for 69lb male boxer. I ordered sm/medium instead of l/xl. When I think XL Im thinking Great Dane not a boxer. So error on the larger size. The brace seems well made.

I have a boxer that is 74lbs..too small and too short, I'll be going to Costco for now on, I saw a review about it being a waste of money , but I thought I would try it for myself..(smh)
IF YOU HAVE A LARGE DOG  DO NOT PURCHASE!!!

My 50# boxer loves her new jacket.  It could be about 1-2 inches bigger Velcro around the neck as it keeps popping off.  Also needs to have a nope in it where her harness hooks

When it says XL believe it.  Very wide, would work for a 300lb tall guy.  Gave to my son-in-law who is 250

Our 50lb boxer took a 6XL - the 6XL is a little snug on her chest but going up would have made it too long and probably too big around her girth.  This is so cute on (we bought the yellow/green).  I might order another one in black because they are so cute.

I order a large as per instruction and measurements, but it did not work for my boxer...it justsat in his narrow part of his waist...didn't cover his penis at all...now if he was well endowed it might have covered the end of it...so ill fitted, I ended up giving it to my friend who has a westie..and it fitted him

Great lightweight gi at a good price.  I spent a while reading feedback on sizing before ordering the A4 size.

I'm 6'2", 210 lbs, 44" chest, 32" waist.  Out of the packaging, the A4 was somewhat oversized for me.  The top was very loose, but after one warm wash and two hot cycles in the dryer, the top fits almost perfectly.  The pants are also very large, especially in the waist, but the cinch system makes them fit well when tied tightly.

The "Large" size fits my 75-pound dog perfectly. The first time, I put it on upside down. Look at the pictures in the instructions.

These boxers run a bit big. Also, they are pretty longer (longer than the standard boxer you'd get in a multi-pack of Hanes) and the legs were really wide. I can't see these being worn comfortably under a pair of pants.

This tie out will hold my 50 lb dog and a tiger. I went slightly oversize...

Hard to find tapered fit boxers at the store.  Been ordering online for awhile.  Husband is between sizes, so size large is a little loose for him.  Otherwise, it's what he was looking for.

I bought a Large to use for leg days/running in the gym. I'm 6', 214 lbs, 33" waist and the Large size fits awesome. It is made out of a thick material that seems very durable. I would definitely purchase it again.
