The Boston is a longer sports shirt for men and specially designed for athletic performance. The regular fit sports shirt has a rounded neck and is made of a lightweight material. Because of the extra lengths and the HEIQ Smart Temp ™ and HEIQ Fresh ™ technology, this sports shirt is super comfortable and keeps you feeling cool and fresh during exercise. The Boston sports shirt has a reflective print on the back so that you stand out when exercising in the dark.


These longer sports shirts for men are made of lightweight, elastic material (100% polyester) for optimal freedom of movement during exercise. We teamed up with HEIQ to make use of the proprietary technology they developed: Smart Temp ™ (Intelligent thermoregulation that keeps your body cooler) and HEIQ Fresh ™ (long-lasting odour control). These technologies keep you cool and fresh for a long time.


This sport shirt is available in sizes S- 3XL and in 3 different lengths. Our size guide:

  • Standard Long Fit (2cm longer than usual, for men till 1.85m)
  • Long Fit (6cm longer than usual, for men from 1.85m)
  • Extra Long Fit (10cm longer than usual, for men taller than 2m)

This is how to wash

  • Machine- or hand-wash only. The long T-shirt must not be dry-cleaned.
  • To avoid wearing it out, do not tumble dry your nanotechnology shirt. Hang it out instead.
