How to Find Your Best Fit
The easiest way to choose your size is to measure a T-shirt you already own and compare it to our chart.
1. Lay your favorite T-shirt flat on a table or bed and smooth out any wrinkles.
2. Measure the Chest Width from underarm seam to underarm seam.
3. Measure the Body Length from the highest point of the shoulder, next to the collar, straight down to the bottom hem.
Our unisex tees generally run true to size.
If you're between sizes or prefer a more relaxed fit, we recommend sizing up.

OUR STORY
The Best Part of Hiking
Trail Grins was built on a trail — somewhere between a ridiculous uphill, a much-needed snack break, & the kind of laugh that makes the whole day worth it.
That's what every Trail Grins design is made for — the shirt that makes a stranger smile, sparks a conversation, & makes the whole hike better.
THE SHIRT
Wear It Everywhere
Not just for the trail. These are the shirts you reach for on a coffee run, a road trip, a lazy Sunday — because they say something true about who you are without you having to explain yourself.
Wear it once and someone will ask where you got it. That's just how it goes.
Quick FAQ — Good to Know.
I'm between sizes — which should I go for?
Size up. Our tees are pre-shrunk and true to size, so when in doubt the larger size is the safer call.
Check the size chart on this page for exact measurements before you order.
Will the print still look good months from now?
Yes — if you treat it right. DTG printing with premium water-based inks means the print goes into the fabric, not just on top of it.
Cold wash, inside out, low heat — do that consistently and the print will stay sharp long after the trail memories fade.
Can I change or cancel my order after placing it?
We move fast — every tee goes into production quickly after your order comes in.
Contact us immediately at cs@trailgrins.com and we'll do everything we can to catch it in time.
No promises, but we'll try.
Is this a good gift for a hiker?
Absolutely. You already know someone who makes every trail better just by being there.
Every Trail Grins design captures something specific & true about hiking life — the kind of gift that makes them laugh, nod, & wonder how a t-shirt understood them so well. And think of you every single time they wear it.
Just check the size chart before ordering.
