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 took a risk and I bought 3 t-shirts for gifts for my husband, my brother and my son. All three were great. I loved the quality and the colors. My husband put his on immediately and loved it. It held up great in the wash… no shrinkage! The other two are in the mail so will have to wait for the rest of my review.
Great quality and fit. Also a nice selection of options in other categories as well. I'll be back again.
ps: I do admit to altering the shirt, as I do with all my T's, by removing the sleeves. Sorry.
Soft, substantial fabric in a beautiful light denim blue. Best of all is the message - I plan to wear it when I vote in the midterms!! I love it and recommend their products!
Love my new T. Happy to represent Lake Ontario. Quality shirt and artwork. In fact, we just ordered 3 more shirts today with Scottish and Celtic themes.
Love this shirt! Wearing it right now! Got a positive comment from a fellow shopper at grocery store today!
Fabric is great and the color is beautiful. Thank you!
I love the Lake Ontario tee shirt and the blue colour is perfect.
I ordered two of these as I was not sure which size would fit my wife. I found the tee shirt runs a little large and she was fine with the medium. I decided to keep the large for myself.
Special thanks for getting both sizes delivered in time for her birthday. Job well done.
Great quality, fast shipping, terrific and subtle message. I got one for myself, then decided to send one to my friend. Her husband saw it and had shirt envy, she she ordered one for him! I’m wearing mine today and 2 people have asked me for the link to get themselves one! Absolutely love it.
Very good t-shirt and very good customer service. I first ordered a shirt that was too small. I contacted customer service and they responded quickly. I followed the instructions to get a new shirt and return the too small one and everything went perfect. The only note about the shirt size, in my opinion, they run on the small size. And I order a lot of different shirts.
P.S. - I love wearing my Lake Ontario shirt out in public for everyone to see and read.
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.
