Whether you call it a shacket or a shirt-jac, you can be sure this latest offering from Filson doesn’t take any shirt-kets. Their mid-season outerwear piece is oiled and insulated to keep that cold sludge at bay.

Filson has long been known for their Tin Cloth; well the Cover Cloth is its lighter weight 8.5oz. cousin that’s just as water repellent. The Shirt-Jac has two layers, both inside and out, that sandwich 100g quilted insulation, house four pockets, and is covered in snap buttons. It doesn’t give a Jac-Shirt about how rainy it is.

You can pick up your portmanteau for $380 at Cultizm.
