Duckworth Comet Loose Crew

A workhorse for hiking in sub-45°F temps.

“The warmest shirt I’ve ever worn,” says one veteran tester after three seasons in this midweight crew. Double-layer construction (with polyester jersey next to skin and Rambouillet merino on the outside) traps a layer of insulating air in between and creates a pleasantly springy fabric. It wicks faster than all-wool shirts, making it a workhorse for hiking in sub-45°F temps. $80; 12 oz.; m’s S-XXL, w’s XS-XL; duckworthco.com
