A Field Guide to Autumn Flannel: Why a Brae Flannel Shirt Should Be in Your Kit

The Fabric of Autumn.
When the temperature drops and the mist sits low on the water, there is one fabric you reach for without thinking. This is a guide to wearing flannel through the season.
Flannel has been the working shirt of the Scottish countryside for generations. It is warm without being heavy, soft without being delicate, and it improves with every season of use. In autumn — when the days are short and the air bites early — it earns its keep more than any other fabric.
This guide covers what to look for, how to layer it and how to make it work from the first light to the last.
What Makes Good Flannel
Good flannel begins with the weight. Lightweight flannel looks the part but offers little warmth; heavyweight flannel smothers. The sweet spot is a medium-to-heavy brushed cotton or wool-blend that sits close to the body and traps warmth without bulk.
The Brush
True flannel is brushed — a process that raises the fibres slightly from the woven surface, creating the soft, slightly napped texture that holds warmth. A well-brushed flannel feels warm to the touch even before you put it on. It also ages beautifully: the surface softens and the colours deepen with washing and wear.
The Pattern
For field use, muted plaids and earth-tone checks work best. They sit quietly in the landscape and move easily between the hillside and the lodge. Avoid loud patterns — they can spook quarry and look out of place in the countryside.
As a Base Layer
On milder autumn days, a flannel shirt worn over a thin merino base provides enough warmth to move comfortably without overheating. Roll the sleeves and open the collar for temperature control.
Under a Gilet or Fleece
The classic autumn combination: flannel shirt under a wool gilet or heavyweight fleece. The flannel provides core warmth; the outer layer adds insulation over the torso without restricting arm movement.
Under a Waxed Jacket
When the rain arrives, a flannel under a waxed cotton outer creates a fully waterproof, breathable system. The flannel wicks any moisture that gets through; the wax sheds the rest.
At the Lodge
A well-cut flannel shirt in a classic check needs nothing above it at the fireside. Tuck it in or leave it out — either way it reads as considered without being overdressed.
Caring for flannel: Machine wash cold on a gentle cycle. Avoid high-heat drying — flannel shrinks. Lay flat or hang to dry and the brushed surface will hold its texture season after season. A quality flannel shirt, properly cared for, will outlast several synthetic alternatives.
