Seventy Degrees SD-CT3 Seamless Carbon Thermal Base-Layer Pant – Unisex Grey

Your legs work harder than you think under riding trousers — trapping heat in summer, losing it in winter, and sitting in sweat on a long haul. The Seventy Degrees SD-CT3 is the base layer that fixes all three, worn directly against the skin from the first kilometre to the last.

Key Features

• Seamless carbon-fibre knit — no seams, no pressure ridges under your trousers
• Active thermal regulation — keeps leg temperature stable in heat and cold
• SPF50 built into the fibre — structural sun protection that never washes out
• Silver-ion antibacterial — odour-free through multi-day touring
• Antistatic system — no crackle or cling under synthetic riding pants
• Machine washable, quick-drying, unisex — four dual-size ranges XS-S to 3XL-4XL

The Carbon Fabric

The SD-CT3 is knitted from an ultra-fine carbon-fibre yarn in a continuous tubular structure. That fibre pulls moisture off the skin and spreads it across the outer face of the fabric, where the large surface area lets it evaporate fast — so your legs stay genuinely dry even during hard riding, rather than clammy the way a cotton or basic-polyester layer leaves them.

Sun Protection That Stays

SPF50 UV protection here is a structural property of the carbon construction, not a chemical coating printed on the surface. It doesn't fade, crack or wash out over the life of the garment — useful on open bikes and long summer days where the sun works through lighter trousers.

Hygiene and Comfort

An antibacterial treatment is bonded to each filament — silver ions that interrupt the bacteria responsible for odour, so the pant stays fresh across back-to-back touring days without a daily wash. The antistatic system safely bleeds off the charge that builds between synthetic layers, killing the little shocks you get peeling kit off at a fuel stop.

Fit and Sizing

The seamless tubular knit wraps the leg like a second skin — close, highly elastic, and completely free of the internal seams that dig in when you're tucked into a riding position for hours. Choose your range by height and build; between two ranges, size up for length. Available XS-S, M-L, XL-XXL and 3XL-4XL, unisex.

Care

Machine wash cool, no fabric softener (it clogs the wicking structure), line dry. The performance properties are engineered into the fibre and survive repeated washing.
