Seirus Thick N Thin Headliner
We like how it balances warmth and breathability; the thin top layers fit neatly under a helmet while the fleece neck provides cozy insulation where you need it most.
Why we like it:
Low-profile fit ideal for wearing under helmets or goggles; true to size.
Features and Functions:
Perfect for cold, variable days when you want full coverage without overheating.
Fit and Sizing:
Ultra-thin, wicking Thermax® hood paired with a technical Polartec® fleece neck-up delivers targeted warmth. Flat seam construction enhances comfort, while the 4-in-1 design transitions between helmet liner, balaclava, scarf, and neck-up.
Bottom Line:
Dual-fabric headliner with Thermax® top and Polartec® fleece neck for warmth and versatility.
