Unzipped Heart | No. 310, Unisex Long Sleeve T-Shirt

$40.00
Select Size

Printed and ships free from US warehouses • Arrives in 3-6 days

The unzipped heart finds a home on this long sleeve, representing the protective layers we wear and the courage it takes to pull them back. The bold red graphic serves as a centerpiece for a thoughtful, layered look.

An intentional silhouette that balances the weight of a heavy zipper with the lightness of an open heart.

We exclusively use Bella + Canvas 3501 blanks for our minimalist long sleeve designs because they hit that rare balance of softness, structure, and everyday durability. The fit is clean and unisex, the feel is light but substantial, and the long sleeves make it an easy layer you’ll keep reaching for—comfortable enough to live in, polished enough to style up.

We choose Bella + Canvas 3501 because it holds its shape without feeling restrictive, prints crisp and clean for long-lasting designs, and is built with details that elevate the finish: side-seamed construction, a classic crew neck with a coverstitched collar, and 2″ ribbed cuffs that keep the sleeves sitting right. It’s also made with a tear-away tag for a smoother, more minimal feel.

Material specifications: Solid colors are 100% Airlume combed ring-spun cotton. Heather colors are 52% combed ring-spun cotton, 48% polyester. Athletic Heather and Black Heather are 90% combed ring-spun cotton, 10% polyester. Fabric weight is 4.2 oz./yd.² (142.4 g/m²) with 32 singles for a soft, refined finish.

All long sleeve shirts are ethically sourced from blanks manufactured in Nicaragua, Honduras, or the United States, ensuring consistent quality and responsible production practices for every design we release.

We create each product only when you order it — zero waste, zero excess inventory. Our made-to-order process takes 3–4 days before shipping, but this thoughtful approach helps us eliminate overproduction and reduce our environmental impact.

Rather than contributing to fashion waste, every ichinichi design is printed fresh specifically for you. No mass production, no unsold inventory ending up in landfills. It's sustainable fashion by design — slower, more intentional, and better for the planet.

Your product doesn't come from a warehouse pile; it's created with purpose, one order at a time.

Yes! We ship worldwide with free international shipping. Orders ship from the closest warehouse to you - US orders from the US, EU orders from the EU, etc. Allow 2-5 business days for production, then shipping time based on your location (US: 3-6 days, International: varies by region).
