We're Chris and Rachel, a small family brand in Raleigh, North Carolina — halfway between the Blue Ridge Mountains and the Atlantic Coast. We design every shirt in-house, and we print with trusted partners here in the USA to get your order out fast.

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.

We know you're used to two-day Prime, but every shirt is printed to order just for you — so it's worth the small wait. Orders usually ship within a few business days, and once yours is on its way, delivery takes another 3-5 business days. Most land on your doorstep within a week.

Shipping is always free on orders over $75. You'll get an email with a tracking number as soon as it ships, so you can follow it all the way to your door.

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.

Not yet — we currently ship within the United States only. We'd love to bring Isle & Glen overseas down the road, so keep an eye out.

Sizing can be tricky, so there's a full measurements chart on every product page. Because Comfort Colors are garment-dyed and preshrunk, we recommend sizing up if you're between sizes or just prefer a roomier, lived-in fit. Tees come in S–4XL, long sleeves in S–3XL, and sweatshirts and hoodies in S–5XL.

We print on Comfort Colors 1717 — the heavyweight, garment-dyed, 100% ring-spun cotton tee that's considered the gold standard for vintage-feel shirts. Soft from day one, preshrunk, and made to get better with every wear.

If anything arrives damaged, defective, or just not quite right, reach out within 30 days and we'll make it right — no questions asked. Email us at support@isleandglen.co with your order number and a photo, and we'll take care of you with a replacement or a refund.

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