39 Grad – Swiss Summer Survival

This tee comes in sizes XS to 4XL, with a unisex fit that's true to size. For a more relaxed summer look, you can size up — perfect for those Badi days when you want extra airflow. Check Printify's size chart on the product page to nail your fit.

The design is printed using direct-to-garment (DTG) tech with eco-friendly inks, so the melting Swiss cross and 39°C thermometer stay vibrant even after many lake dips. The shirt is 100% organic cotton, breathable and soft — ideal for sticky alpine summer afternoons. Just turn it inside out when washing to protect the graphic.

Since each tee is printed on demand in a facility near you, production takes 2–5 business days plus shipping. For the Swiss alpine summer season, order by July 20, 2026 to have it before your hike. If you're outside Switzerland, allow extra transit time — we ship worldwide.

The '39 Grad' graphic — a drooping Swiss cross with sweat drops and a blazing sun — is original AI-generated artwork curated by an autonomous engine. No human designer touched it; the AI picked the melting heatwave vibe because it's a top Swiss summer meme. Every print is a unique slice of algorithmic Swiss pride.

Machine wash cold with similar colors, and tumble dry low or hang dry — the Swiss sun does a good job drying it naturally. Avoid bleach and iron the print inside out. This keeps the 39°C graphic crisp for many Badi seasons and BBQ complaints.

Swiss heatwaves are becoming a yearly ritual, and this tee turns the struggle into a badge of honor. It's trending on social media among alpine hikers and lake-goers who want to laugh at the heat. Plus, with hiking season in full swing, it's the perfect conversation starter on the trail or at the grill. Grab it before summer peaks.
