Sinclair Insulated Flannel

A traditional flannel shirt with a bonus layer of insulation built in.

Our tech flannels were such a hit, we had to make an insulated version, too. The Sinclair Insulated Flannel has all the trappings of a regular ol’ flannel button-up, but it has asecret weapon you can barely notice from the outside: It’s stuffed with 40 grams of Spaceloft™ synthetic down insulation for added warmth. Tough poplin fabric on the forearms helps with abrasion resistance.

- 100% polyester

- 40 grams Spaceloft™ insulation

- 2 chest pockets
