My experience:
1. Harkila pro hunter jacket. Very warm (too warm for summer). Lots and lots of pockets (including excellent poachers pocket at back). Relatively thorn proof. Hood is useless. Not terribly waterproof - fine for light showers or short periods in heavy rain, but soaks through quite fast, then becomes extremely heavy and takes ages to dry. Soaks through at elbows immediately when crawling. My verdict: excellent jacket for woodland use, milder conditions, high seat use. No good for the open hill, unless you’re certain it’s not going to rain much.
2. Swazi Tahr. Substantially more waterproof that the Harkila. Will cope with hours in heavy rain and crawling. However, will start to seep at the chest zip eventually. Neoprene cuffs are badly designed: soak up water that then transmits to your sleeves, which end up wet to the elbows. Hood is ok, but restricts vision a lot, and will allow quite a lot of water in if rain coming from front. Almost no pockets: just a pair of hand warmers at the front. This is a very serious design flaw, and in my opinion makes the jacket close to useless. My verdict: a reasonable jacket for something like beating, where you don’t need much equipment with you. I also use it a lot for dog walking in heavy rain.
3. Norrona Kvinerrad. Extremely expensive. Generally well designed and very waterproof (at least initially). Essentially what the Swazi should have been. Loads of pockets in very well thought out places. Outstanding hood - best I have ever tried- will keep you sealed in even with a gale blowing in your face. However, does have flaws: again, has stupid cuffs that wick water into your sleeves. Also has a little pouch on the inside at the back that is meant to be where you can slide in a bit of foam mat to sit on. This is completely useless, but also wicks water up your back - I cut mine off. Probably has too many seams and vents, so that after reasonable use it does start to seep. My verdict: the best I have tried for hill stalking in really awful weather. But probably too expensive for what it is.
I have handled shooter king in a shop, and was not convinced by the build quality.
