Belong to a Scottish women’s org. Daughters of Scotia. Wore this to our meeting last nite. Everyone loved it. Can’t wait till it’s cool enough to wear the sweatshirt! With the same fantastic design.
Love the quality of this t shirt and the vintage look. Perfect blend of US and Scotland for the World Cup and 4th of July. Extremely comfortable and a great fit. I ordered the large and it's roomy without being baggy.
Just love this T-shirt and am so proud to be Scottish particularly after seeing the Tartan Army during the FIFA world championship. Thank you for offering this.

It is exactly what The picture showed! I love the connection between America and my Scottish roots! I wish the neck were a little wider. Maybe it will stretch out the more I wear it.
Absolutely love this shirt. Love anything Comfort Colors, and it's so soft. The design is amazing: I wore it the week of July 4 and received a ton of compliments on it. It's going into my regular rotation!
The fit is true (as I hoped), the material is high quality, and the design appears that it will hold up under multiple washing/drying cycles. I'm very happy with this shirt that displays my heritage and my country at the same time in this significant year for the USA. Very happy!
My husband is American and I am Scottish. We have lived as a family in both countries. We love both. This thistle shaped American flag was a perfect gift for my husband, especially as both our countries qualified for the Word cup.
As a naturalized American citizen from Scotland, the vintage thistle t shirt is my new favorite piece of clothing. It’s nicely styled with muted colors and is of quality material.
It’s a good weight; not at all flimsy like some t shirts. I bought one for my daughter as well.
I purchased the T-shirt with thistle in red white and blue motif to reflect my status as a naturalized American citizen from Scotland. Of all the various clothing I own with that theme, this one is my new favorite.
It’s stylish and the print is subdued enough to be worn anywhere without appearing flashy. Just perfect.
I like the shirt quality and design - except the crew neck is very tight and very high. I wish this shirt had a v-neck option - especially a neck line like the life is good v necks.
I'm of Scottish heritage and am a proud American so this thistle and American flag combo shirt really brought it home for me. It's a beautiful print, it fits as the sizes are true and it makes me very proud to wear it for the 4th of July to celebrate our nations birthday ! Thank you for an extra special product !

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.
