Brynje does not seem to readily available in the US. They work great and keep me dry but I will like to get the long sleeve top and maybe the bottom.
Here is a link for reference:
The Brynje mesh-underwear is actually handed out to Norwegians doing their national service in Northern Norway, i.e. it's been tested and approved in pretty cold areas... ;-)
And yeah, super expensive also here. And super worth it.
Seems like you can also buy directly from their website (www.brynje.no) and with our currency being pretty bad these days that might not be a bad idea.
