Frequently asked questions

Compared to a regular running T-shirt, the Haimont Trail Running T-shirt offers the following features:

  • During long runs in humid and hot conditions, your body generates a lot of sweat and becomes damp. That’s why we use quick-dry fabrics and breathable mesh panels to improve airflow, speed up heat dissipation, and help sweat evaporate faster.
  • The S-size Haimont T-shirt weighs just 57 g, ultra-lightweight to reduce fatigue, making it ideal for long trail runs, back-to-back runs, or mountain runs.
  • Seamless laser-cut construction reduces skin irritation or chafing caused by friction during long runs, improving comfort and performance.
  • The T-shirt uses Swedish Polygiene® antibacterial and odor-control technology to prevent bacterial growth at the source, minimizing odor and keeping you confident on every run and in social situations.
  • During long-distance races, when runners swap wet clothes at aid stations, Polygiene® helps prevent wet clothes in backpacks or humid conditions from developing odor or bacteria.
  • Whether training or wearing it casually, the T-shirt stays fresh longer, requires fewer washes, and lasts longer.

The Haimont Trail Running T-Shirt is made from 100% lightweight polyester featuring high-performance Polygiene® anti-odor mesh fabric.

Reflective strips along the torso improve visibility and safety in low-light conditions. Designed for rugged terrain and extended activity, it offers exceptional breathability, comfort, and functionality.

Odor control is very important for trail running T-shirts, even more so than for regular road running T-shirts. Trail running often involves long distances lasting several hours or a full day, and in prolonged, humid conditions, bacteria multiply more easily, making odor a bigger issue than short urban runs. Haimont premium trail running T-shirts use Polygiene® silver ion antimicrobial treatment to keep your shirt fresh and odor-free during extended runs.

Absolutely. Haimont trail running T-shirts are often better suited for hiking or trekking than regular casual or sports T-shirts. Their lightweight, quick-drying, and breathable design reduces load during long hikes, prevents discomfort or chill from damp clothing, and makes hiking more comfortable overall.

A trail running T-shirt doesn’t need to be skin-tight or baggy—the key is a comfortable, close fit that prevents friction, enhances ventilation, and dries quickly.

The Haimont shirt features an athletic cut tailored for trail running. Side 5cm hem slits improve leg movement, while a tag-free heat transfer label at the back neck and large underarm ventilation panels keep you comfortable mile after mile.

Every detail is built around the demands of long-distance trail running.

They can be machine washed, but it's not recommended. Haimont trail running T-shirts are made of 100% lightweight high-performance polyester mesh, which is sensitive to high heat, vigorous agitation, bleach, and fabric softeners. Machine washing may reduce durability. If machine washing is necessary, use cold water on a gentle cycle, and avoid fabric softeners and high-heat drying.

Haimont trail running T-shirts are quick-drying and breathable. Simply lay them flat or hang them in a well-ventilated area to dry naturally. Avoid high-heat drying or prolonged direct sunlight, as high heat can damage polyester fibers (causing shrinkage, deformation, or reduced antimicrobial function), and strong UV rays can accelerate fading and reduce elasticity.

Most trail running T-shirts weigh between 80–150 g, depending on fabric and sleeve length. Haimont trail running T-shirts weigh around 50–60 g, significantly reducing the load when carrying gear during long-distance trail runs.
