Patagonia Fjord Flannel Shirt vs Carhartt Tencel Fiber Series Twill Plaid Shirt

The Fjord Flannel is the warmer, softer shirt: a brushed cotton flannel shell with a taffeta lining and 80-g recycled insulation, so it works as a light jacket on cold mornings. The Carhartt Tencel Twill Plaid is a heavier 12-ounce loose-fit work shirt with a pen-stall pocket and two lower pockets, built for layering over a tee on the job. Buy the Patagonia for warmth and a clean casual look; buy the Carhartt for roomy fit, pocket utility and hard-wearing twill.

• Choose the Fjord Flannel if you want a lined, insulated flannel that doubles as a light jacket and you prefer a trimmer, buttoned-up look.
• Choose the Carhartt Tencel Twill Plaid if you want a loose, roomy work shirt with a pen pocket and lower pockets for tools and gloves.
