A bright core, a spinning ring of light and not a single word needed.

This cosmic shirt for men carries Synergy Energy Core, an original RaZits emblem of a white starburst at the heart of a spinning wheel of pastel light. It's comfortable from morning to midnight, and a natural gift for the stargazer who spots the first star before anyone else.

The design: a starburst core in a pinwheel of light

The whole print is one round emblem centered on the chest. At its heart burns a bright white starburst, a single point of light with fine rays shooting out in every direction. Around it, about fourteen curved, feathered crescent blades sweep clockwise like the arms of a pinwheel, and thin white spokes link each blade back to the core, so the emblem looks as if it's turning while you watch.

The blades shift color as they circle: pale gold and cream on the upper left, soft peach-pink on the lower left, then lavender and violet across the right half. Behind them, a glowing violet-magenta ring and a faint globe-like grid of curved lines float in a scatter of tiny star specks. It reads as a radiant energy sphere in neon gradients, part cosmic mandala and part charged-up power core, with no figure or scene to pull focus.

Synergy is the idea that separate parts moving together make more than any one of them could alone, and that is exactly what the emblem shows: every blade turns around the same bright center. It's a quiet reminder that the best days happen when your people, your plans and your own spark all line up.

A cosmic shirt in fine cotton with a close cut

• Soft 100% cotton, combed and spun into a fine, smooth yarn, so it feels gentle against your skin
• Lightweight 4.3 oz/yd² (145.8 g/m²) fabric, easy to wear on its own or under an open shirt
• Fabric that's shrunk before sewing, so there's less shrinking in the wash
• A fitted cut that sits closer to the body, finished with a classic crew neck
• Tear-away label for clean, irritation-free wear: pull it off and there's no itchy tag at your neck

Who it's for

For stargazers and backyard astronomers, space and sci-fi fans, lovers of mandala and sacred geometry art, and anyone who likes glowing digital art that doesn't need words to make its point. If you game, you may read the glow as a power core charging up. It belongs at a night under the stars, a concert, a planetarium show or a weekend road trip, and it makes a good present for Father's Day, a graduation, a birthday, the holidays or no reason at all.

Quick answers

Which size should I order?

It's a men's tee with a close cut, so your usual size fits snug through the chest and one size up leaves extra room. Check your chest measurement against the size guide next to the size options.

Can I get every size in every color?

One shirt color starts at small rather than extra-small, while the rest come in every size listed. Pick your color first and the size menu will show exactly what you can order.

How does the glow look on the brighter shirts?

The white core and pastel blades print clearly on every shade. On the darkest shirts the soft shadow behind the emblem melts into the fabric, while on the brighter ones it shows as a faint, lighter circle of haze.

Are there any words in the print?

No. Synergy Energy Core is the name of the design, not a printed slogan, so the emblem reads as pure art from across the room.

Is there a print on the back?

No, the back is plain, so the round emblem on the chest gets all the attention.
