Jonne Koski Shirt is rated 4.6 out of 5 by 18.
Rated 3 out of 5 by from Poor color saturation in back graphic I bought this shirt because of the graphic on the back (waves). As advertised, the graphic has distinct white, blue/purple, and background off-gray cotton. My shirt, as received, had very poor color contrast on the bottom wave. The color was very similar to the cotton color making the graphic not as advertised. Bottom line, the graphic seemed extremely worn and did not resemble the advertised graphic. Shirt fit as expected (my first Rogue shirt) and was comfy.

Rated 5 out of 5 by from Perfect weight! Great shirts. Rogue has a 50/50 blend or a tri-blend. The tri-blend seem to shape up a little longer than the 50/50 shirts after a couple of washes. These are great athletic fit shirts. I now have 21 in total. I buy a tri-blend in XL and the 2X in the 50/50 shirts. I would make sure to check the blends out before picking your size. I'm 5'10" and prefer the tri-blends. I wish they had some choices in white.

Rated 5 out of 5 by from Perfect Shirt Incredibly soft and true to size. The design looks great, feels great and holds up to many sweat sessions and runs through the wash. Would buy again. Thanks, Jonne Koski & Rogue Fitness!

Rated 5 out of 5 by from Sweet shirt! Great quality as always. Typically wear a medium especially with the Rogue shirts. This one is a touch larger than some of the others. It is longer too. Still fits great without looking like a garbage bag on me. Still snug enough to stay in place when doing handstand push-ups.

Rated 4 out of 5 by from color.... love the design and the Norwegian flag on the sleeve. but the color is a bit off. 6'2'' 180lb, M is a bit too tight, L will be perfect. Go Koski! can't wait to see you compete in 2019!

Rated 5 out of 5 by from EPIC I get looks from wearing this shirt everyday. It’s absolutely perfect in every way, it’s hard to want to take off. Of course, now permanent sweat smell has been engrained into the fabric for eternity. I’m surprised it hasn’t melted yet. Soft and shapely, perfect texture and size. Can not wait to get it out of the dryer And wear it to do everything and anything. Love every rogue shirt I have.

Rated 5 out of 5 by from Great Shirt! I bought this shirt around one month ago and have to say that I love it, as a taller athlete I love the extra length. The shirt is a lot more breathable then other shirts too! I love the design, JONNE WEAR THIS SHIRT AT REGIONALS!

Rated 5 out of 5 by from Probably my new favorite top Really nice material, and fits perfectly - Particularly around the waist when most top feel flabby. The color is different than as pictured, as pointed out by another reviewer. Still absolutely love it!
