First Impression- I pulled this rashguard out of the box and was immediately impressed by how it looked. I took it out of the plastic that it came in and the material is very soft and seemed thicker than other rashguards that I have. Looks great and I cant wait to try it. I also really enjoyed the japanese theme throughtout this rashguard.

Fit and Finish- I wear a shirt size medium so that is the size of the rashguard that I got and either my body is sized weird or the rashguard is. I found it to be quite tight on my arms and upper body but looser around my waist and stomach. However the quality and finish of this rashguard are top notch. No threads out of place or loose and the stitching is very high quality. I also noticed this rashguard is longer then most that I have which I think is a good thing as you could get a good tuck into your shorts with out it rolling or creeping up on you. All of the graphics are sub laminated but they seem to be even deeper in to material then most so I highly doubt that they are going to crack or peel.

Stand up- For stand up this rashguard works excellent. Not only did it stay where it is suppose to it did a very good job of wicking away moisture. I also found that it kept my body just the right temperature as some rashguards I have used in the past have caused me to over heat due to either thickness or how breathable the material is. The more I use this rash guard the more I like it.

Ground- This rashguard also works very well on the ground. Once again does an excellent job of wicking away moisture. On the ground it did creep up a little but nothing that I could not deal with and I did not ever have to re-tuck it. I also decided to wear this under a gi and for the most part kept me from getting gi burn. While under the gi it did an excellent job of keeping me just the right temperature.

Pros-

High Quality

Very Breathable material

Good moisture wicking

Sub laminated graphics 

Cons-

Weird Sizing

Overall- I really liked this rashguard and other than the odd sizing it is an excellent product. If you are looking for a rashguard at the top of food chain then I would give this one a try. This is definitely a product I would recommend. The price for this is around $60.
