Product Details

Overview & Technology

Bern's Men's Premium Zipmold Winter Liner is engineered to integrate seamlessly with the Brentwood helmet, adding thermal protection without bulk. The liner uses a low-profile Zipmold interface to lock into the Brentwood shell while maintaining the helmet's original fit and venting characteristics. The interior is finished with a soft microfleece next to skin for moisture wicking and comfort; the exterior layers combine a thin wind-blocking fabric and closed-cell foam for insulation. The included BOA-style micro-adjuster lets you fine-tune tension quickly for a snug, consistent fit even with gloves on.

Key Features & Construction

The liner's construction focuses on real-world winter riding needs: a microfleece lining for warmth, a wind-resistant outer layer to cut cold airflow, and a molded foam core that follows the helmet's interior contours. Stitching and seam placement are optimized to prevent pressure points while under a helmet strap. Practical highlights: • Zipmold-compatible molded foam for secure helmet integration and minimal slippage. • Microfleece lining for thermal comfort and moisture management. • BOA micro-adjuster for fast, precise tensioning — works with gloved hands. • Low-profile design keeps helmet vents usable and profile sleek.

Fit, Compatibility & Care

This liner is specifically designed for the Bern Brentwood helmet and pairs directly with the helmet's Zipmold retention interface. The listed variant (SM) matches the smaller Brentwood shell sizes; check your helmet size to pick the correct liner. When installed properly the liner does not interfere with the Brentwood's fit system or safety performance. Care is simple: hand wash with mild soap and air dry to preserve the foam and fabric. Avoid machine washing, high-heat drying, or solvents that could degrade the foam, BOA dial, or attachment points. Shipping dimensions: 6.6" x 3.1" x 5.1", weight: 0.3 lb.

Who This Liner Is For

If you ride year-round and want a warmer, more comfortable helmet in cold weather, this liner is for you. It's tailored to commuters, winter road riders, and urban cyclists who use the Bern Brentwood as their everyday helmet and need a fuss-free upgrade for chilly conditions. Riders who value a tidy, low-profile look and quick adjustment will appreciate the BOA micro-adjuster. If you need extreme cold protection for multi-hour winter outings, consider pairing this liner with a balaclava or thicker outer cap for additional insulation.

Frequently Asked Questions

Will this liner fit other Bern helmet models?

This liner is designed specifically for the Bern Brentwood using Bern's Zipmold attachment interface. It may not fit other Bern models or non-Bern helmets reliably — check compatibility or contact Forest Bikes if you need help confirming fit.

How does the BOA adjuster work on a liner?

The BOA-style micro-adjuster on this liner tightens an internal tension cord to fine-tune the liner's fit inside the helmet. Turn the dial to increase tension and pull the liner snug; press the release to loosen. It's engineered for quick adjustment even with gloves on.

Can I wash the liner in the machine?

Hand washing with mild soap is recommended to protect the molded foam and BOA components. Rinse gently and air dry away from direct heat. Machine washing or tumble drying can damage materials and void expected performance.

Will the liner affect helmet safety or ventilation?

When correctly installed in a compatible Brentwood helmet, the liner is designed to preserve the helmet's original fit and safety characteristics. Its low-profile construction maintains much of the helmet's venting, though you will get extra insulation that naturally reduces direct airflow.

Is this liner warm enough for very cold temperatures?

The microfleece and closed-cell foam provide solid warmth for typical cold-weather commuting and winter rides. For extended exposure in sub-zero conditions you may want to pair it with a thin balaclava or insulated cap for added protection.

Buying Guide

When choosing a helmet liner, confirm compatibility with your helmet model and size — this liner is built for the Bern Brentwood and comes in size SM for smaller shell fits. Look for features that match your riding style: microfleece for moisture management, wind-blocking fabric for commuting, and a good adjustment system (like BOA) for on-the-fly fit changes. Consider the climate you ride in: a low-profile winter liner like this balances warmth with vent retention, making it ideal for cold but active rides. For extreme cold or multi-hour exposure, layer with a thin balaclava or insulated cap.
