Size Guide

Everything you need to find your perfect fit.

Diagram showing where half chest and length are measured on a t-shirt

All top measurements are of the garment laid flat — not body measurements. The easiest way to check your size is to measure a t-shirt you already own and love the fit of.

Please note: as with all garment production, measurements can vary slightly piece to piece — typically within ±1.5cm of the figures below.

Construction Details

Ripstop Effect Knit Reinforced grid structure resists tears and abrasion without adding weight. Technical protection that stays completely invisible in wear.	Instant Breathability Open-knit construction allows heat and moisture to escape fast. Stay cool mile after mile, even as the pace climbs.
Raglan Sleeve Construction The raglan cut eliminates the shoulder seam entirely — removing friction hotspots and enabling a full, natural range of arm drive.	Self-Fabric Bound Collar No thick ribbing. The crew neck is bound with the same performance fabric — lies flat, looks clean, and sits comfortable against the neck.
Twin-Needle Hem Finish Sleeves and hem finished with twin-needle stitching for durability and a clean, flat edge that won't curl after repeated washes.	Side Seam Construction Side seams give the tee a clean, shaped silhouette that holds its form wash after wash without twisting or pulling out of line.
