Product details

A low-profile thermal cycling beanie designed to sit beneath a helmet for cool-to-cold riding, with a recommended working range of approximately -5–10°C. This PDP includes two distinct constructions, so choose the version based on the balance of insulation, drying speed and coverage you need.

Warm Haze uses brushed four-way-stretch fabric with quick-drying, sweat-wicking characteristics. It is the lighter, lower-bulk option for riders who generate more heat or prioritize faster moisture management beneath the helmet.

Warm Journey uses 290 g high-weight fleece for greater insulation, combined with a breathable jacquard sweat-management zone, ergonomic stretch shaping and extended ear coverage. It also adds a reflective logo detail and recycled nylon yarn.

Both versions use a close one-size stretch fit intended for under-helmet use. After adding any thermal head layer, re-check helmet position and retention-system adjustment to make sure the helmet remains secure and comfortable.

Temperature comfort varies with riding intensity, wind exposure, helmet ventilation and individual cold tolerance. No waterproof rating is specified, so this product is not positioned as rain protection.

PRODUCT FEATURES

Warm Haze — Moisture-Managing Stretch

Elastic quick-drying construction moves with the head while helping move perspiration away from the skin during cool-weather rides.

Warm Haze — Brushed Four-Way Stretch

A brushed four-way-stretch fabric adds light thermal retention while maintaining softness, mobility and close under-helmet fit.

Warm Haze — Anatomical Low-Profile Fit

Close head-conforming shaping and precise stitching reduce excess material for a stable fit beneath a cycling helmet.

Warm Journey — 290 g Thermal Fleece

A 290 g high-weight fleece construction increases insulation for colder rides while keeping a soft next-to-skin feel.

Warm Journey — Jacquard Moisture Management

Breathable jacquard fabric supports sweat transport to reduce clamminess during sustained cold-weather riding.

High-elasticity material and head-contoured shaping create a close fit across a range of head shapes without unnecessary bulk.

Road, gravel and commuting rides in cool-to-cold conditions where low-profile under-helmet warmth and moisture management are priorities.

Fit & sizing notes

One-size stretch construction intended to sit close to the head beneath a cycling helmet. After adding the beanie, re-check helmet position and retention-system adjustment so the helmet remains secure and comfortable.
