Half zip collar for breathability

Laser cut ventilation in key high breathability areas
Flat stitch seams
A BREATHABLE TRAIL TOP
The weave on the R-Light fabric is quite open, when held up to the light it looks like a sieve, with many holes, this is part of the weave to give maximum airflow. For additional ventilation there are laser cut holes in key excess heat areas to help move moisture even faster.
A zipped neck gives additional ventilation but also the short collar helps protect from possible strap chafe from a pack. As is common on much of Raidlight's clothing, additional storage pockets give you little places to store additional food or your phone or keys. The R-Light LS Zip Top has 2 zipped pockets to sides at the bottom of the T-Shirt. Accessible even when wearing a pack/race vest.
The recycled polyester of which 80% of the R-light TOP is made provides great breathability, but not only that! This material comes from recycled plastic bottles, so it uses less water and makes it possible to recover plastic waste.
80% recycled polyester and 20% elastane
Polyester is a very breathable material
Elastane provides a very useful stretch for ease of movement
