Why We Created It

A foundational layer for cool to cold conditions, the AROW Baselayer uses Pontetorto® Tecnostretch—an Italian fabric engineered for warmth, stretch, and moisture control. Weighing just 200g, it’s ultra-light, fast-drying, and packable, with a brushed inner for comfort and a smooth outer for clean layering.

The high collar and half zip offer quick thermoregulation, and it meets mandatory kit requirements for ultra-distance races—ideal for year-round use, long days, and unpredictable conditions.

In Black.

Features

→ Our first product in the Fragments collection, utilising high performance 'deadstock' fabrics
→ Constructed from 100% recycled Japanese Rip-Stop (37g/m2)
→ Laser cut details provide excellent breathability with eye-catching aesthetic
→ Two-way zip for heat regulation
→ Windproof, water repellent and weighing in at only 50g

Sizing & Fit

→ The AROW Baselayer is standard fit, and a unisex product - we'd advise women to choose a size down (so if you usually wear a S, take an XS).

Materials

The AROW Collection is the result of a local supply chain of designers, pattern-makers and seamstresses who produce high-quality garments in working conditions that are a world away from typical sporting apparel manufacturers.

Cut, sewn and finished at Petratex, Portgual - at the very forefront of sports apparel tech globally.

Crafted from premium Japanese Rip-Stop fabric made from 100% recycled nylon. By repurposing deadstock and over-ordered materials, we reduce waste and manufacture small runs of elite products, merging sustainability with performance.

Care

→ 100% Recycled Nylon

→ Wash cold, line dry, do not iron or bleach
