Welding Cap with Neck Flap Guide
A standard welding cap protects the top of the head from sparks and spatter. A welding cap with a neck flap extends that protection to the back of the neck - a critical exposure point for overhead welding and any welding position where the neck is not covered by the helmet or jacket collar.
What Is a Welding Cap Neck Flap For?
The neck flap on a welding cap serves three functions:
-
Spark and spatter protection - the back of the neck is exposed when the head tilts forward during welding. A neck flap covers this gap between the helmet shell and jacket collar.
-
UV radiation protection - the neck receives UV exposure from arc welding, especially in overhead and vertical-up positions.
-
Heat shielding - for overhead stick welding with significant spatter, the neck flap reduces burns from falling spatter that clears the jacket collar.
Most important for: Overhead welding positions, pipe welding (where position changes frequently expose the neck), and structural steel welding.
Does a Neck Flap Replace the Need for a Jacket Collar?
No - it complements the jacket collar. The neck flap fills the gap that exists between:
- The bottom of the welding helmet shell (back)
- The top of the jacket collar
This gap is exposed every time the welder tilts forward. A neck flap bridges this gap. A jacket collar (especially a flip-up collar like on the Lincoln Electric K2989) provides the primary barrier at the jacket level; the cap neck flap provides secondary coverage above it.
Best practice: Neck flap cap + standing jacket collar - provides continuous coverage from helmet shell to jacket body.

How to Wear a Welding Cap with a Neck Flap
-
Bill (brim) facing backward - the standard welding position. The bill faces the back of the neck, extending coverage downward. The neck flap hangs down over the back of the neck.
-
Helmet positioned over the cap - the cap sits between your head and the helmet’s headgear. The neck flap exits below the helmet shell at the rear.
-
Adjustment: The cap should sit low enough that the neck flap reaches the jacket collar with minimal gap. If a gap remains, a jersey-knit balaclava or FR tube can fill it.
Sizing Welding Caps
Unlike most work headgear, quality welding caps are sold in hat sizes (6-1/2 through 7-3/4+). Measure your head circumference at the widest point:
| Hat Size | Head Circumference |
|---|---|
| 6-1/2 | 20-1/2” |
| 6-5/8 | 20-7/8” |
| 6-3/4 | 21-1/4” |
| 6-7/8 | 21-5/8” |
| 7 | 22” |
| 7-1/8 | 22-3/8” |
| 7-1/4 | 22-3/4” |
| 7-3/8 | 23-1/8” |
| 7-1/2 | 23-1/2” |
| 7-5/8 | 23-7/8” |
| 7-3/4 | 24-1/4” |
FAQs
What is a welding cap neck flap for? It bridges the gap between the welding helmet shell and jacket collar at the back of the neck, protecting exposed skin from sparks, spatter, and UV radiation - especially in overhead welding positions.
Does a neck flap replace the need for a jacket collar? No - it works with the jacket collar to provide continuous neck coverage. The jacket collar protects at the collar level; the cap neck flap covers the gap above it.
Which brands make caps with a longer neck flap? Comeaux Caps is the most recommended brand among professionals for welding caps, including extended neck coverage options. Available on Amazon (B00UUETSFO and others) and ComeauxCaps.com.
