Family-Owned Small Business
Isle & Glen is a truly small business — one family and a few helping hands. Every design is our own, and every shirt is printed to order and shipped right here in the USA. When you buy from us, you're supporting a small American shop.
I’m buying these for everyone’s bday this year. The short colors are great… not your typical RGB standards and the print is high quality.
Gonna buy a Denali one next!
The Gulf of Mexico Tshirt came in promptly. I couldn’t wait to try it on and it’s so soft and comfortable! It fits pretty true to size maybe slightly on the larger size. So I’m gonna tie it in a knot and make it look super cute would absolutely recommend!
The shirt appears to be of good quality and is very comfortable. Super happy with it. However, it took just over a month to receive. Not sure if that's on USPS's end or what?
Store owner replied:
Thanks so much for the kind words about the shirt—we’re really glad to hear you love it!
As for the shipping delay, we took a look and it looks like USPS lost track of the package for a stretch in the middle of June. That kind of delay definitely isn’t the norm, and we’re so sorry it took that long to reach you. We know how frustrating it is to be left waiting, and really appreciate your patience. If you have a similar issue in the future, don't hesitate to reach out and we'll work with USPS to get it taken care of as soon as we can. -Rachel
It is and always will be the Gulf of MEXICO! Great shirt!
I’m happy with the material- not as soft as I thought it would be, but after a wash and dry, I can tell it’s excellent quality, and will hold up well! I’m 5’10, typically XL women’s t-shirt- the Large unisex fits perfectly.
Only a racist narcissist thinks he can change the name of a body of water simply to boost his own ego. It has been the Gulf of Mexico since 1550, and it will always be known as the Gulf of Mexico to everyone who's not kissing the 🍊 🤡's 🫏. THIS T-SHIRT LETS EVERYONE KNOW YOU ARE ON THE SIDE OF SANITY AND DEMOCRACY! Plus after you wash and dry it, it is soft as butter!
The shirt is screen printed, not a vinyl transfer. It's so much better quality than many online T-shirt vendors. It looks just like the online images, well done! Support this small business!
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. Our tees come in S–4XL.
What are the shirts made of?
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.
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.
