The 5.11 SETH Shirt Jacket seems like it was based off of the old 1940s McGregor Flannel Jacket made in black and red check pattern. This is a timeless looking style and it features buttoned shirt style cuffs for a sporty and classy look. A good layering jacket over a tee and sweater when it’s colder outside make it great for almost any kind of weather. This jacket is so versatile and it can be paired with jeans, and boots for a good look. The timeless material lends itself well to comfortable shirts that look great with anything and everything. In 1914 ad copywriter William Laughead personifies lumberjack folk hero Paul Bunyan in a series of pamphlets for the Red River Lumber Company. At the turn of the 20th century the flannel shirt became a symbol for rugged men. Modern-day flannels are usually made with cotton, wool, or synthetic fibers.

I wear mine nearly every day during some of the colder months. This is a perfect holiday gift for someone, and it can be used while hiking, fishing, camping and just about anywhere that’s not too cold. I like the fact that it is machine washable for easy care and a fresh feel.

The Seth Shirt Jacket combines a classic buffalo check pattern. It is made with 5.8-ounce 100% cotton twill that has been brushed for extra softness. The Seth Shirt Jacket provides continuous warmth thanks to a 7.3-ounce fleece lining in the body and 80g insulation in the sleeves. The sleeve lining is: 100% polyester taffeta, 1.9-oz, and the sleeve Insulation is: 100% polyester, 2.4-oz. I liked the jacket immediately when I saw it.

A few things to note: It gets softer after every wash. I recommend that you hang dry it, and don’t use your dryer if you want the material to last. You don’t have to worry about ironing it. I recommend washing and drying sparingly or laying flat to dry. The best flannel shirts actually get a little bit softer the more you wear and wash them. The jacket is roomy around the torso however, I recommend that if you have an athletic build that you go up one size.  You will need some more room in the arms and shoulders if you are a weight lifter. It has two external pockets on the chest and the side panels of the jacket.

5.11 uses what they term RAPIDraw™ snap plackets. This is a nice feature however one of them broke off after only a few months of use. This could be a material flaw uncommon to the kind of snap they use; something you should be aware of. They use side seam vents to allow fluid movement. The jacket is warming but still manages to be relatively light is to its credit. It comes in two colors: Ranger Green Plaid, or Cobalt Blue. The Cinder Plaid seems to be sold out from time to time.

I think you’ll like this jacket. It is low maintenance, layers well, and is affordable. It is a versatile fabric with a deep history that stretches back centuries. It’s a good look for anyone. This SETH shirt flannel is more oriented towards casual daily wear over workwear. It has a nice cut, is an ideal weight. I would like it to have a thicker or larger collar. Excellent for Spring to Fall as an everyday flannel for yard work and camping. Fantastic construction at this price. It prices in at $110 and I’ve seem them on sale for $88.00.
