In reply to BFG:
Sadly, nowhere stocks Jottnar anymore as it is EXCLUSIVELY online through their website.
The main reason I believe you don't see many people wearing it now is because it was only 'widely' available in shops for a year and heavily advertised during that time. Now, the business is still small in terms of staff members and outgoing costs as it's just one building in Cardiff to pay for. I believe, but may be wrong, that they rely on these contracts of mountain guides etc and word of mouth that their gear is amazing to make sales.
I have heard from one of the few employees that they're looking to expand back out to "real world" shops in the next couple of years. Again, rumours.
I like to think of Jottnar as similar to Crux, where Carol refuses to expand the business too rapidly and the demand and hype for it has outgrown the supply.
I've never owned Jottnar but have only heard great things about the workmanship, design, quality and customer service.
