Frequently Asked Questions

What size should I get?

Sizing can be tricky, so there's a full measurements chart on every product page. These have a relaxed unisex fit — take your usual size for a regular fit, or size up for the roomy, oversized look. Our sweatshirts come in S–5XL.

What are the shirts made of?

We print on the Gildan 18000 — the heavyweight fleece crewneck that's the workhorse of quality sweatshirts. Cozy from day one, pill-resistant, and made to hold its shape through years of regular wear.

Where are your shirts printed?

Right here in the USA. Every shirt is printed to order and ships from within the US, so nothing sits in an overseas warehouse or travels across the world to reach you.

Are Triangle Threads and Isle & Glen the same?

Yes — same company, same two people, same shop. Isle & Glen is simply the new name.

Triangle Threads is where we started. We began by designing shirts for America’s National Parks and the wild places we love to explore.

Ireland and Scotland were always our other great passion, and somewhere along the way that passion took over and became the full-time thing. Isle & Glen grew out of it.

So if you spot Triangle Threads on a package, an email, or somewhere on this site — that’s still us. Same family, same care, same shop. Just a name that finally matches what we love making most.

How long until my order arrives?

Every shirt is printed to order just for you. Orders usually ship within a few business days, and delivery takes another 3-5 business days — most land on your doorstep within a week. Shipping is always free on orders over $75.

Can I change or cancel my order?

Yes, within 24 hours of placing it. Every shirt is printed to order, so after that it's usually already in production. Just email us at support@isleandglen.co with your order number and what you'd like to change.

What if it's not right?

If anything arrives damaged, defective, or just not quite right, email us at support@isleandglen.co within 30 days and we'll make it right with a replacement or a refund — no questions asked.

How do I get in touch?

Email us at support@isleandglen.co or use our contact page. We reply within 24 hours, and usually within 12.
