The Mock Neck That Makes Every Outfit Look Sharper
You know the look. The guy who walks in wearing something simple and somehow looks more put-together than everyone else.
Usually it comes down to one piece. A top that fits right and sits right. No baggy chest. No slouchy shoulders. No sleeves bunching at the wrist.
TitanFit™ is a slim-fit mock neck long sleeve in a soft cotton-poly blend that follows your shape without squeezing — finished with a clean stand collar that gives every outfit a more intentional edge.
Wear it solo. Layer it under a jacket. Throw it under an open shirt. It does the work for you.
One of our most reordered men's tops this season
✓ A SLIM FIT THAT ACTUALLY FITS
Tailored through the chest, shoulders, and sleeves — no extra fabric pooling, no boxy drape. The silhouette stays clean from collar to hem.
✓ A MOCK NECK THAT HOLDS ITS SHAPE
The structured stand collar keeps its line all day. No slouching, no flopping over — just a polished neckline that elevates a basic top into something more.
✓ SOFT FABRIC THAT MOVES WITH YOU
The cotton-poly blend is lightweight, breathable, and has just enough stretch to follow your range of motion. No stiffness out of the bag. No itch through the day.
✓ WEARS UP OR LAYERS DOWN
On its own with chinos or jeans for a smart-casual look. Layered under a jacket, blazer, or open button-down when the temperature drops. One piece, multiple outfits.

Still have questions? We've got you covered.
How do I pick my size?
We recommend going one size up from your usual US size. The fabric runs snug by design — sizing up gives you the cleanest, most comfortable fit, especially across the chest and shoulders. Check the size chart above for exact measurements.
Is the fabric thick or thin?
Lightweight enough to layer under a jacket or button-down without bulk, but substantial enough to wear on its own. Soft, breathable, and not see-through.
Will the mock neck stay up or flop down?
It holds. The collar is structured to keep its stand-up shape all day — no sagging, no rolling. It sits clean against the neck and looks intentional from morning to night.
Can I wear this on its own, or is it just a base layer?
Both. It's polished enough to wear solo with chinos, dark jeans, or trousers for a smart-casual look. And the slim cut and clean lines make it a strong layering piece under jackets, blazers, or open button-downs.
Will it shrink in the wash?
Wash cold and tumble dry low and you'll keep the original fit. The cotton-poly blend holds its shape well wash after wash.
