Let customers speak for us
Gave this as a gift and she loved it!! Her favorite park, and now a favorite shirt.
It's very comfortable and functional. I get two kinds of comments: that it looks nice and/or curiosity about the design. When I tell them what the topo map is from, they nod knowingly, as I grew up in Tacoma so I saw "the mountain" and visited on the regular as a child.
This is my favorite of my TrailBest shirts! I love Yosemite, so it's fun getting to wear a map of one of my favorite places. On top of that, the color is beautiful, the fit is great and the performance of the material is just what I expect for a shirt expected to go places and do things with me. Highly recommend!
My new favorite shirt of one of my favorite places. Well done
On top of reminding me of my visit to Yellowstone’s Grand Canyon, this hoodie is very comfortable and made with great quality. I would absolutely recommend and buy again.

💦🌞❄️ Performance Fabric
Made for days that start hot, get stormy, and end cold. Breathes well, wicks fast, and won’t stay wet. Light enough as a top, warm enough as a layer.
Katahdin rises from the Maine wilderness with a presence that feels both remote and absolute. Sheer granite faces, narrow ridgelines, and alpine tablelands define a mountain shaped by weather and time. From the forests below to the exposed heights of Baxter Peak and the Knife Edge stretching across the sky, the landscape is rugged, raw, and unforgettable. This long-sleeve performance tee reflects that terrain, tracing the ridgelines, basins, and routes that lead to Maine’s highest summit. Anyone who’s crossed the Knife Edge, felt the wind sweep across the tableland, or stood at the northern terminus of the Appalachian Trail will recognize the lines in this design.
Built for Maine’s demanding mountain conditions, the lightweight fabric manages moisture on long climbs while providing coverage against wind and rapidly changing weather. UPF50+ protection adds comfort during extended time above treeline where shade is scarce and exposure is constant. It’s a layer for people who know Katahdin isn’t just about reaching the summit—it’s about the challenge, the solitude, and standing at the end of a long journey in one of the wildest places in the Northeast.
