Rated 5 out of 5 by from Great look and great fit I have several shirts from Rogue and this one again has great quality and a great athletic fit. The shirt is slightly darker blue in reality, but looks excellent.

Rated 2 out of 5 by from Not worth the money The Quality is not very good (open seams). The imprint is very pale.

Rated 4 out of 5 by from Nice shirt Good quality and sizing, but the finnish flag is wrong way (the cross should be heading forward not to back side)

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 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!
