Not part of our Summer Collection, but it still works well in summer.

Fact:

The color (#F3EDE4) reflects heat and pairs effortlessly with seasonal palettes. Made from 100% carded cotton, it’s a natural fiber that’s breathable and absorbs sweat. With a 240 GSM (7.1 oz) fabric weight, it can feel warm under peak midday sun. However, the dropped shoulders and boxy cut allow airflow, balancing out the heavier fabric. That makes it best for evenings, shaded outdoor wear, or indoor summer styling.

Summary:

☁️ Light tones that reflect heat. 🌿 100% carded cotton — breathable, sweat‑absorbing, natural. ⚡ Oversized fit + boxy cut = airflow.

Fact: Lightweight T‑shirts (<150 GSM or under 4.5 oz) are best for hot weather. They’re designed for maximum breathability — ideal for hot climates and outdoor summer days. However, keep in mind that they can be too thin or slightly transparent in lighter colors. Heavyweight T‑shirts (>200 GSM or 6+ oz) aren’t made to cool you down in summer — they’re made to elevate your look. They shine in structure, silhouette, and aesthetics. Between them sits Midweight T‑shirts (150–200 GSM or 5–6 oz). Midweight fabric balances breathability and structure: it feels solid without being heavy and it breathes better than heavyweight.

What We Offer: We offer two fabric weights in our Summer Collection: 190 GSM (5.6 oz) and 206.8 GSM (6.1 oz). Both are garment‑dyed and made from 100% ring‑spun cotton for breathable comfort, ensuring they stay wearable even in warm weather.

Conclusion: Our Midweight and Heavyweight T‑shirts work well in summer — especially indoors or during evenings when structure and style matter most.

Fact: #644E6D belongs to the Violet color family with low saturation and a neutral brightness profile. It’s not as cool as White (#FFFFFF) or pale tones under direct sun, but it remains wearable with the right fabric and setting.
