STÖRNCH T-Shirts
Our new STÖRNCH T-Shirts are manufactured from a heavyweight 50% cotton DryBlend fabric that wicks moisture away from the body. Available in Black, Red and Navy, plus sizes from Medium to XXL, you’ll look smart, feel comfortable and stay fresh all day (maybe). And they’re free on Promo500.

STÖRNCH Baseball Cap
Top-off your work outfit with the tough STÖRNCH baseball cap. Manufactured from heavy brushed cotton, this smart cap is the perfect onsite accessory.

STÖRNCH Safety Knife & Border Biscuits
The most recent redesign resulted in the STÖRNCH Safety Knife becoming one of our most popular tools ever, and a must-have for AC & Vent installation engineers. Alternatively, if you just fancy something tasty for the office or sitehut we’ve got our Border Biscuits Classic Sharing pack.
