Sizing for Wera

We have not yet published a measurement chart for Wera. If you are between sizes or new to the brand, contact us with your measurements and we will check the garment for you, or visit the Adelaide showroom.

How to measure

  • Chest: under your arms, around the fullest part, arms relaxed at your sides
  • Waist: around your natural waistline, tape held loose
  • Hips: around the widest part
  • Inseam: from crotch to floor, no shoes

Measure over the underwear you would ride in and keep the tape horizontal. All measurements refer to your body, not the garment.

Two rules that work across every brand. Buying a jacket to wear over a jersey? Take your normal size or size up. Buying a thermal jersey to wear under a jacket? Size down if you are between sizes and want it close.

Compare every brand side by side in our full size guide, or visit the Adelaide showroom to try before you buy.

High quality Impaktor bits for hexagonal socket screws. The Impaktor technology offers an above-average service life even under extreme circumstances. Enhanced friction resistance, thanks to the rough diamond-particle coating on the bit tip, prevents any slipping out of the screw head. Hex-Plus ensures a greater contact surface in the head of the screw. The notching effect is therefore reduced to a minimum and damage to the screw head more or less eliminated. 1/4" hexagon, suitable for holders as per DIN ISO 1173-F 6.3.
