The facts.
DescriptionThe whole story▼
Cold-weather kit has one recurring weak point: the neck-and-face interface. The Seventy Degrees SD-CT4 seals it with a seamless carbon-fibre neck tube that does more than a standard neck warmer — one accessory that reconfigures into three.
Key Features
- Seamless tubular carbon knit — no internal seams against face, neck or ears
- Three configurations — neck warmer, headband, or helmet liner
- Natural thermal regulation — insulates while the skin still breathes
- Silver-ion antibacterial — odour prevention across multiple riding days
- Antistatic — no charge build-up against the helmet liner
- One size; rolls down to a pocket-sized pack
One Tube, Three Jobs
Worn conventionally it's a wind-blocking neck warmer that seals the helmet-collar gap. Pulled up over the ears it becomes a headband on cool mornings. Slipped over the head it works as a thin, hygienic helmet liner. The flexible seamless construction takes each shape without bunching or a single seam to chafe.
Carbon-Fabric Performance
The carbon knit regulates temperature naturally — insulating against cold air while letting moisture move through and evaporate — so it doesn't turn into a cold damp band the way a saturated cotton tube does. The silver-ion treatment, bonded at fibre level rather than sprayed on, keeps odour-causing bacteria in check across a multi-day trip, and the antistatic system stops the charge that otherwise builds between the tube and a synthetic helmet liner.
Fit and Care
One size, stretching cleanly for any of its three roles, and compact enough to live in a pocket for the ride you didn't dress for. Machine wash cool, line dry — the performance properties are engineered into the fibre.
