You have two jackets in one with the Black Diamond Boundary Line Mapped Insulated jkt. It provides exterior protection and interior insulation thanks to the Lavalan wool (German brand). You immediately feel the benefits, your body heat stays inside and you warm up fast. This could be a problem at the end of the season, but in December or January the thermal qualities are very much appreciated.
The other noticeable point with this jacket is its weight: 1 kilo. You don’t actually feel the weight when wearing it freeriding but if you go out backcountry skiing it would be better to opt for two jackets, one protective and another insulating (down or synthetic like Primaloft®).
We loved its overall comfort due to its stretchy fabric and ample cut. The collar and chin area is very soft, the hood is very well-designed to fit over a helmet, you can easily turn your head without restriction. Without the helmet the sides of the hood are very supple so need adjusting with the cord at the back of the head.
The wrists are comfortable because they sit easily over a pair of gloves, even big ones.
This Black Diamond Boundary Line Mapped Insulated jkt has a great idea you can easily remove the snow skirt as it is attached with a zip, very practical, simple and efficient.
The central zip is waterproof but the underarm zips aren’t. Which is a shame because the Black Diamond membrane is pretty performant and the jacket can go up against severe conditions. In wet snow or rain you quickly soak up water under the arms.
The waist is adjustable and there are numerous deep pockets for packing away all your bits and pieces.
The Black Diamond Boundary Line Mapped Insulated jkt is a very good skiing jacket that is warm, a little bit heavy and very comfortable. Its reasonable price makes it good value for those who want to ski with a renowned brand.
