Not tried Merino?! 'Kin hell. If you're not wearing merino, you're doing it wrong. I've not not worn merino at any given time for about a year now. Been wearing it on the bike for about 2 years.
I get most of mine from Howies. Wait until a sale and jump in quick. However, I've just ordered some 75 quid merino polo shirts from the Spring preview. Cycle to work, wear them all day, look smart in meetings and ride home. Repeat for a few days.
I got married in howies merino. Seriously. I did 4 days and nights
in the Cairngorms in the summer, cycling and bivvy bagging, same merino
top the whole time and then went to a party in the same top. I wore merino
leggings non-stop for 9 days snow boarding, including sleeping in them. Still smelt fresh after that.
Likesay, if you're not wearing Merino right now, you're wearing the
wrong thing.
