Pretty awesome that this set comes with almost everything that you need to pull off a fairly convincing nordic/viking cosplay. The only thing that you really HAVE to add on to this would be some kind of footwear. I used this as my base layer and added a few accessories to dress it up and bring my entire costume together. Overall, this is a steal for the value of what you get. Granted, I have a few notes on the contents because it's not perfect.
1. The shirt itself is really cool, probably my favorite aspect of the costume. I got the dark green version and it was very comfortable. One thing that was a bit confusing was the sizing. You can't select individual sizes for the shirt or the pants, they come as a set. So I got the mediums. I washed the items when they arrived and the shirt itself fits fine, but is almost a little too short. To me, a shirt of this style should be a little bit baggy. But it's fine. The material is pretty breathable as well, and having buttons on the sleeves to keep your sleeves rolled was a nice feature.
2. The Pants remind me of a cross between joggers/thin pajama pants. They have an elastic band that you can cinch down. For me, the mediums were a bit too baggy. It felt like my shirt was a little too small and pants were a little too big, but the worked out fine. The cinch at the bottom of the legs for me didn't do too much since the pants were already a little too baggy. They have pockets, so that was convenient. Sometimes you never know if a costume will have pockets, but thankfully these did and they were rather large so you can fit your personal items in them.
3. The gauntlets were fine, PU leather and looked pretty cool. They are very stiff and can be a bit uncomfortable shifting and spinning around on wrists. The color of the gauntlets themselves also did not match the color of the belt that came with this set, so that was odd. I actually used some brown shoe polish to darken them a little bit. I recommend at least trying the stretch and bend the gauntlets a little to get the stiffness out.
4. The belt is extremely long! I'm a thin guy so it was extremely long. Again, PU leather, kind of cheap feeling. I liked the pattern on the belt just to add a bit of detail. Don't count on this lasting you a long time though, it feels rather cheap and just for looks but it's fine. Thankfully it's pretty easy to trim down if it happens to be too long.
Overall : 3.8 out of 5, not perfect but great for a budget costume and a nice base layer that you can add different accessories and such to make it look even better.
