Sysum - Men's Merino One Long Sleeve

The Sysum - Men's Merino One Long Sleeve from Sysum is ideal for warm weather running or as a light thermal base layer in colder conditions. The long sleeves offer added sun protection or extra warmth during cooler, windy efforts.

Key Features

90 g/m² Merino Blend
Made from a 90 g/m² blend of merino wool and recycled polyester, providing natural and efficient temperature regulation.
Warm-Weather and Cool-Weather Versatility
Retains moisture in warm conditions to reduce sweating and hydration needs, while trapping heat when worn as a base layer in colder environments.
Odour-Resistant & Antibacterial
Naturally odour-resistant and antibacterial, making it suitable for multi-day use with minimal washing.
Contoured Fit & Low-Irritation Seams
Contoured men’s fit designed for optimal fabric performance, with flatlock shoulder seams positioned on the front to reduce irritation under a vest pack, and angled side seams for a precise, comfortable fit.
Layering-Friendly
Pairs easily with Sysum’s thermo layer tees to help you find the perfect temperature combination.
