The DNF Core Vest is built from the ground up. A 240gsm heavyweight cotton vest that sets the new standard for everyday essentials.

Inspired by the clean aesthetic of modern streetwear and the discipline of endurance sport, this sleeveless cut delivers structure, comfort, and quiet confidence. The fabric weight gives it that premium feel, thick but soft, durable but comfortable, made to hold its shape through every wear.

Perfect for training, recovery, or off-duty days, the Core Vest bridges the gap between performance and lifestyle. The fit is relaxed through the body with a slightly dropped armhole, giving it that effortless, athletic silhouette.

It’s simple, bold, and unmistakably DNF — built for those who live the mindset, not just wear the logo.

*Fits true to size*

About DNF

DNF stands for Do Not Fail - a mindset that doesn’t stop at the finish line.
Our gear reflects that standard: no compromise, no shortcuts, just premium quality built to outlast trends and test time.

This is more than a vest.
It’s a statement of how you show up — every single day.

For the Ones Who Keep Showing Up.

Every run. Every rep. Every reason to quit — and you don’t.

The DNF Standard

Every piece of DNF gear is built for the ones who do the work; the early alarms, the brutal climbs, the miles no one sees.

We use premium, performance-tested materials designed to outlast sweat, weather, and excuses. But this isn’t just about fabric, it’s about mindset.

DNF clothing is worn by runners who push past comfort, who finish what they start, who understand that pain fades but quitting lasts forever.

Whether it’s a training day, race day, or rest day; this is kit that reminds you what you’re made of. DNF: Do Not Fail. Ever.
