Five Brother Thermal Knit Lined Snap Front Hooded 9oz Flannel Jacket - 5480

Five Brother has been building workwear flannel since 1890, and the Thermal Knit Lined Snap Front Hooded Flannel Jacket is the fullest expression of what the brand does: heavyweight cotton flannel built for the job, layered with real warmth construction, and cut to fit the way workers actually need outerwear to fit. This is not a fashion flannel made heavier with a liner. It is a purposefully constructed working jacket that answers every question about cold-weather outdoor work in a single garment - warmth at the core, insulation through the sleeves, and a lined hood that keeps the neck and head covered when the temperature and wind combine against you.

The body is 9oz 100% cotton flannel, brushed to a softer surface than raw flannel and yarn-dyed to ensure the color stays consistent and true through years of field use and repeated washing. Yarn-dyed flannel locks the color into the fiber itself rather than applying it as a surface treatment, which means the jacket holds its look through the abrasion and laundering that workwear endures. The interior of the body is lined with a 6oz thermal knit that adds a dedicated warmth layer between the flannel shell and the wearer's torso, and the sleeves are lined with 2oz quilted material that insulates the arms without adding the bulk that some sleeve constructions create when a worker needs to move freely. The hood is lined with a 60/40 sweatshirt blend that holds warmth at the neck and head without the stiffness of a structured hood.

FiveBrother logo pewter snaps close the front of the jacket and secure the pockets and cuffs, giving the jacket the finished detail that sets it apart from anonymous workwear at the same price point. Two large chest pockets with flaps provide secure carry for the items workers need to access throughout a shift, and flannel-lined lower front pockets add warmth to the hand pockets during cold holds and breaks. The relaxed fit gives extra room through the chest for layering over a base layer or midlayer, and extra-long shirttails provide coverage when bending and reaching without the jacket riding up and exposing the lower back to the elements.

Q&A

Q: How warm is this jacket compared to a standard lined flannel shirt?
The Thermal Knit Lined Hooded Flannel Jacket adds three layers of warmth that a standard lined flannel shirt does not have: the 6oz thermal knit body lining, the 2oz quilted sleeve lining, and the sweatshirt-lined hood. A standard lined flannel typically uses a single layer of quilted or fleece lining in the body without insulated sleeves or a lined hood. For outdoor workers in consistently cold or windy conditions, those additional layers make a meaningful difference in how long the jacket can sustain comfortable working temperature.

Q: What does yarn-dyed flannel mean and why does it matter?
Yarn-dyed flannel means the color is applied to the cotton yarn before it is woven into the fabric, rather than dyed after weaving. Because the color is in the fiber itself rather than on the surface, yarn-dyed flannel resists fading from UV exposure, washing, and abrasion significantly better than piece-dyed alternatives. For a working jacket that will see heavy outdoor use over multiple seasons, the color consistency of yarn-dyed flannel is a practical durability feature as much as an aesthetic one.

Q: What is the difference between the regular, tall, big, and big X sizing options?
Regular sizing covers the standard men's proportions from Medium through 2XL. Tall sizing adds extra length through the body and sleeves for taller wearers who typically find regular sizes too short in the torso or arms. Big sizing adds extra width through the chest, shoulders, and waist for larger builds, running from 3XL through 4XL. Big X extends the size range further for the widest builds, running from 5XL through 6XL. Confirm measurements against Five Brother's size chart before ordering, particularly for tall and big sizes where proportional fit varies more significantly.

Q: Can this jacket be used as an outer layer in very cold conditions or is it better as a mid-layer?
The Thermal Knit Lined Hooded Flannel Jacket functions effectively as a standalone outer layer in cool to cold dry conditions, particularly with a thermal base layer underneath. In severe cold, sustained wind, or wet conditions, it works best as a mid-layer under a waterproof or windproof shell. The 9oz cotton flannel body is not wind or water resistant, which limits its stand-alone performance in driving rain or sustained extreme cold, but as a layering piece it delivers the warmth and mobility that make it a daily-wear choice for many tradespeople.
