Overview:

Built for skiers, snowboarders, outdoor workers, and anyone facing freezing conditions, this unisex seamless baselayer set delivers the perfect balance of warmth, breathability, and unrestricted movement. The long‑sleeve top and full‑length pants are each 3D‑knit as continuous pieces, eliminating every side seam and friction point. The result is a smooth, chafe‑free second skin that layers invisibly under mid‑layers and outer shells, providing reliable thermal insulation without adding bulk. Designed for both men and women, the set adapts naturally to different body shapes, making it an ideal foundation for brands targeting the outdoor, snow sports, or cold‑weather workwear markets.

Key Features:

Seamless 3D‑Knit Construction

Both the top and pants are knit in one continuous piece on Santoni machines, eliminating side seams, shoulder seams, and inner‑leg seams entirely. The result is an irritation‑free, second‑skin fit that moves with the body during high‑activity snow sports or long days on the job.

Thermal Insulation Without Bulk

Available in three weight options — lightweight for high‑output ski touring, midweight for resort skiing and everyday winter wear, and expedition‑weight for extreme cold and stationary activities. Hollow‑core fibers or brushed fleece interiors trap body heat while remaining breathable.

Moisture‑Wicking & Quick‑Dry

Advanced hydrophobic yarns actively pull sweat away from the skin and spread it across the fabric surface for rapid evaporation. The wearer stays dry and warm, never clammy — even during intense uphill climbs or heavy labour in freezing temperatures.

Anti‑Odor Built‑In

Silver‑ion or zinc‑based anti‑odor treatments are embedded into the yarn during extrusion, surviving 50+ wash cycles. The set stays fresh through multi‑day ski trips, winter camping, or back‑to‑back work shifts without needing a wash.

Thumbhole Cuffs & Stay‑Put Fit

Long‑sleeve top features integrated thumbhole cuffs that keep sleeves in place when layering and provide extra hand warmth. An elastic‑free, bonded waistband on the pants prevents rolling or digging, while silicone grip strips at the ankles (optional) prevent riding up.

Unisex Design & Fit

Designed to comfortably fit both male and female body shapes with a relaxed athletic cut. Unisex sizing from XS–4XL with proportional grading ensures consistent comfort and performance across the full size range.

Certified Skin‑Safe Materials

All fabrics are OEKO‑TEX® Standard 100 certified, free from harmful substances, and safe for extended skin contact. Optional UPF 50+ protection and anti‑static finishes are available for specialized outdoor or work environments.
