I am in the process of trying to order some of Byrnje's undergarments. They are hard to come by in the US, only the poly net can be had in the US, but a Canadian firm carries the whole line....I am awaiting an order catalog.
I have worn various net materials in the past for many occasions and find it near perfect.
My cotton net is excellent in the warmer seasons (but unfortunately far too tight now :?: ) This stuff is nice under a thin shirt to keep bugs from biting through, and really ventilates nicely. Even though it is cotton it does not get too clammy as most of it is air.
My poly net top is OK but very abrasive under a pack. I wear it for high activity like X-country skiing. This I am looking to replace with the Brynje Super Thermo or possibly their Arctic versions which has a layer of wool over the net.
I have a pure wool net top from Devold, this is pure luxury for lower activity in the cold. It is too warm for local winter wear but perfect in Montana winters. It never feels clammy, but the smaller holes do not ventilate quite enough for higher activity in moderate cold.
I cannot wait to get some of the Brynje garments to replace my small cotton net and my early version polypro abrasive net.
