Sorry to post negatively but you did ask what people thought! I bought one at the time they were flooding the market. I must say the most important part of my gear is coat and trousers, and the trousers failed severely, over and over. All the waterproof tape on the seams went hard, scratchy then brittle and fell apart, the trousers fell apart at the stitching, and they tore at the sheer sight of a bramble. As the waterproof tape fell apart so soon, they were not waterproof and it was a weekly job to sew them back together. They would have been fine for going and standing on a peg and never meeting a bramble, but that's not my type of shooting.
The coat was fine, same material so beware of bramble but not as much bramble at that height/level. Could take a shower but not a soaking. Do not wash it as the shoulders that have the sort of leather look fade incredibly and look awful if you do wash it.
The thermals were ok but I do not think tight/warm enough; fleece was good still use that. And of course a hat that is still going, somewhere in the cupboard!
Within a season of using it I started to value good kit much more that I could rely on. Funny for those around me but I left half my trousers behind one day out on a walk around with my dog and a friend! Caught on a wild rose and they just split up the seam! I then turned to Harkila trousers and jacket, and merino wool thermals, and this year added a swazi tahr coat. A lot of monies worth of kit but of the £200 I spent on my Jahti Jakt kit I had a season out of it and only use the fleece now. Expensive fleece! The harkila trousers are on their 5th year as is the jacket, as for the swazi tahr, superb!
If I was given a jahti jakt kit I would enjoy having something smart looking but keep it for walking the dog. I have had better wear out of army surplus trousers and almost as waterproof.
