Visited my local Sports Direct shop today and they had the Karrimor Event jackets in stock. The Jacket design is quite short, I assume so that it does not cause problems when using a climbing harness. It does not fully cover the crotch or bum so not designed for the "fuller coverage" that Walkers may be looking for although if used with overtrousers it would provide total coverage.
The fit was more "relaxed" than some climbing designed jackets I have tried and I would say that the Event fabric is "mid-weight" with the whole jacket being made of the same weight of fabric. Like a lot of these styles of jacket the water-resist zip is a bit stiff and takes some getting used to. The pockets are mesh lined rather than a double layer of event fabric which means when open they will act as a venting aid (it has no pit zips). The hood appears Helmet compatible and the volume is adjustable for non helmet situations. I would guess that the weight is circa 450 to 500 grams so not ultra light. No weight is given on the "swing tab".
The other "elite" branded garment I looked at was the Transition Soft Shell this is a jacket retailing at £39.99. The fabric is stretch woven, lightweight, no membrane or "backer" fabric and is described as "wind resist" rather than windproof. I would say the fabric, at first glance, is similar to the lighter weight APEX fabric used in TNF jackets. Again no weight quoted.
The other garment I looked at was the X Lite Helium Waterproof/breathable Shell. It is made out of a 2.5 layer fabric described as Weathertite (the generic named used for all Karrimor waterproof/breathable fabrics). In feel it looks a bit like the 2.5 layer Hyvent fabric that TNF use. Some performance figures are quoted on the "swing tag" HH 10,000/MVTR 10,000. The design is similar to the Event jacket but as it is made of a much lighter fabric the weight is less. Again no official weight quoted but I would guess circa 350 gms. The garment is for sale for £59.99.
All two waterproof shells look more suited to Climbing than walking although the cheaper waterproof, the X lite Helium would also be suitable as a "just in case" garment for inclement weather.
All in all the three garments look to be of reasonable quality and offer good value for money at the prices they are on sale for. They are all available in male and female specific fit. The performance of the garments/fabrics "on the hill" is the $64,000 question that I cannot answer. Full details on the Field and Trek or Sports Direct websites (see links given in previous posts.
