Over the past few years I've gone from my hill and hiking clothing being polyprop/synthetic to various Merino wool items (base and mid layers) and some heavier wool shirts & jumpers for outer. I've started to look at tweed as a possible addition to this now I'm shooting as I'm looking for quiet, breathable and water resistant. My Bison Bushcraft shirt has been a revelation, being windproof and warm while not requiring waterproofs for light showers.
Looking at ads for tweed, there's such a vast range to choose from whether it's a simple tweed cap (I've a harris tweed cap I'm currently using) through to goretex lined tweed and prices from basement to 'bloody hell how much?'. What's the difference in the various tweeds and how do you know what's good and what's not. I'm sure it's not as simple as just buying expensive stuff so I'm interested to know what folks here think of tweed and how to go about choosing/evaluating what to buy.
