Your Tee, Your Way - Regular vs Relaxed Fit

Our men's tees come in your choice of a standard regular fit or a premium relaxed fit. So, what's the difference?

Standard Regular Fit Tees
Our Standard Regular Fit Tees are all about easy, everyday comfort. Crafted from 100% soft combed cotton (with the exception of our marle colours, which have a 15% viscose blend for that subtle textured look), these tees hit the sweet spot between weight and wearability. The mid-weight fabric, at 180gsm, is light enough to keep you cool in summer but still durable enough for year-round use. They’re preshrunk to reduce any surprises after the first wash, and thanks to their real-world sizing, you can expect a consistent, reliable fit that won’t leave you guessing. Plus, they're machine washable, making them super easy to care for. These tees are perfect if you want something that feels soft, fits well, and works across any season.
Premium Relaxed Fit Tees
If you’re after something with a little more substance, check out our Premium Relaxed Fit Tees. These are made from 100% heavyweight cotton, offering a thicker, more durable option with fabric weights ranging from 240gsm to 280gsm. Designed for a looser, boxy fit, these tees have that laid-back, oversized vibe, making them great for layering or wearing on cooler days when you want to stay comfortable and warm without compromising on style. Like the Standard tees, they’re preshrunk to minimize shrinking and ensure your fit stays spot on wash after wash. Machine washable for easy care, these tees are perfect for those who love a bit more room to move and a shirt that feels like it’ll last forever. Ideal for cooler weather or for those who prefer a more relaxed, heavyweight feel.

How to Choose the Perfect Size

Choosing the right size is easy! To make sure your new gear fits just the way you like, start by measuring a t-shirt you already own and love. Lay it flat on a smooth surface and measure straight across the front from armpit to armpit. Once you’ve got that measurement, simply compare it to the sizes listed in our guide to find the best match.

If you're in between sizes or prefer a more relaxed fit, we recommend ordering a size up for added comfort. This ensures you’ll get a great fit, whether you’re going for a classic look or something a little oversized.
