Love my FL Red Desert briefs. My UA briefs stink after an hour and don't have the breathability that the merino provides. I wear mine all year long so they get a lot of use. They seem pretty durable with multiple washings. Love the extended legs so they don't ride up. They provide a little extra layering but they breath and wick extremely well. Well worth the money. The briefs can be bought on sale on different hunting sites for around $48-50.
