The Raidlight Performer XP Shirt is a superlight, highly breathable and quick drying shirt, with a well thought out feature set. Ideal for short or long races.
Raidlight says:
This year, the famous Performer top has evolved for even greater performance. Developed initially for Trail, the versatility of the Performer XP finally makes it the perfect top for all races from 5K to Ultra.
What really sets the Raidlight Performer XP Shirt apart from other running shirts is it's excellent feature set, all designed with racing in mind. The shirt comes with a removable race number belt and 2 special pins that won't damage the fabric of the shirt. You don't want to keep pining lightweight fabrics with normal pins as it will damage the fabric over time. These special pins are double sided with a sharp edge that can push through your race number and into any of the holes on the elasticated belt. The pins can also be used on tops replacing normal damaging pins.
The shirt also features silicone grip on the hem to prevent the fabric from riding up and patterned silicone dots across the shoulders to prevent your pack/vest from sliding.
