How do you like it?

FITTED

Closer to the body. Choose your usual fitted-tee width.

RELAXED

More room, easy feel. Go roomier if you're between sizes.

Height & weight fit guide

Quick size estimate, not a guaranteed fit. Height in cm / weight in kg.

Height Weight Fitted Relaxed
160–170 50–60 M L
165–175 60–70 M L
170–180 70–80 L XL
175–185 80–90 L–XL XL–XXL
180–190 90–100 XL XXL

Example: 180 cm / 80 kg → L fitted, XL relaxed.

Guide only. Body shape and fit preference vary. For the best fit, measure your own T-shirt and match the Size Chart above. Chest measurements are more reliable than height and weight alone.
