The race to zero
There are some very simple rules of running. Rule one: lighter is nearly always better. Weight is the enemy – whether it’s your body or your kit. It’s the enemy of going fast. It’s the enemy of going long. And it’s the enemy of running like you ran when you were a kid. Your gear should feel weightless. So we’re building the lightest running system in the world. The mission is to get as close to zero as we can on the weighing scales, so once you put it on you forget it’s there.

A minimalist system of running gear
Race to Zero is an ultralight packable system built for running 5km or 5 days straight. We’re starting with four pieces – a t shirt, shorts, jacket and puffer. Each piece is built with advanced materials, packs down into itself and fits into the palm of your hand. The entire system weighs just 600 grams.

Every piece packs into itself
Every piece in the system packs down into itself in exactly the same way. At the bottom of the t shirt you’ll find a black, zero-shaped pocket. It’s the same black, zero-shaped pocket you’ll find on the shorts and the jackets as well. To pack the jacket up you turn the pocket inside out and push the jacket into it until you’re left with a pouch that fits into the palm of your hand. Once it’s packed down you can stuff it into your race bag, or clip it on using the elastic hanging loop.

Why simplicity matters
Running brings amazing clarity. It simplifies your decision making. And once you start running through entire days or nights, your thinking is often reduced to the very basics: I am hungry. I hurt. I am tired. I would like to sleep now. So we’re building the ultimate minimalist system to reduce your thinking and decision making to a minimum. You won’t have to think about what you pack. And you won’t have to think about what you carry with you.

Works for 5km or 5 days
Ultramarathons are a really fast way of finding out who you are and what you’re capable of. They’re also a really quick way of finding out if your kit works. So the Race to Zero system is designed to see you through the toughest races on Earth. Even the smallest failure point can be enough to drive you slightly crazy on a long enough timescale. If it rubs the first time, you can bet the 10,000th time is going to feel like torture. That’s why we’re building gear that’s quiet, seamless, stretchy, lightweight, and fast drying. It’s designed to not be noticed.

Ultra-lightweight at just 85 grams
The temperature can drop fast when you’re running at night, or at altitude. So you need extra layers that can heat you back up quickly. The trade-off is normally the space and weight they take up in your bag. That’s why the Race to Zero Jacket packs up into a small ball that fits in the palm of your hand, and weighs just 85 grams – under half the weight of an iPhone. Whether it’s on your back or in your backpack you’ll never notice it’s there.

Protects you from the elements
The jacket is built to act as a windbreaker or emergency layer if the wind and rain kick in and the temperatures start to drop. So it’s designed to heat you up quickly when you’re cold. Despite being ultralight, the material is engineered to keep heat in and wind out when you’re moving. The outside of the jacket is also treated with a water repellent coating so light rain simply rolls off its surface, keeping you drier for longer. Once you start sweating again, you can roll it up into a ball and hold it until you need it again.

27 laser cut vents
We’ve laser cut small circular vents into the areas where you sweat most to provide extra airflow when you’re working your hardest. You’ll find two vents under each armpit, three down your spine and ten on each forearm.

Two deep side pockets
You’ll find two large storage pockets on the back of the jacket for gels, water bottles, or maps. The pockets are 20 centimetres deep and are made from a stretchy mesh that expands the more you put inside them.

Breathable, stretchy cuffs
Even the cuffs have had weight engineered out of them. Each cuff is constructed with tiny perforations which allow excess heat to escape and prevent sweat from building up. The cuffs are also stretchy and grippy to create a seal around your wrists to stop cold air getting in.

Works with the Race to Zero Shorts
Weighing just 127 grams the Race to Zero Shorts are built from densely-woven nylon microfibres that are engineered to be the same thickness as silk. Water repellent, fast drying and highly elastic, they’re ultra-soft and lightweight, while being durable enough to work in the toughest races. All the seams and details are laser cut and bonded to reduce the chance of chafing. And the inner lining of the shorts is made from the same Italian material as the Race to Zero T Shirt. The lining is engineered with thousands of tiny perforations to create airflow, while a silver-based antimicrobial treatment fights the odour molecules created by sweat.

Works with the Race to Zero T Shirt
Engineered with thousands of tiny perforations to let air flow in and out, the Race to Zero T Shirt is built to take on the world’s toughest races or your daily training run. Weighing just 113 grams, it’s built with exactly the same ultra-soft Italian material we use to build the inner lining of the Race to Zero Shorts. It’s high-wicking, fast-drying, and stretches with you whatever you’re doing. And a silver-based antimicrobial treatment on the t shirt fights the odour molecules created by sweat, to keep you comfortable whether you’re 5km or 5 days into your run.

Works with the Race to Zero Puffer
The Race to Zero Puffer is the warmest layer in the system. It’s built with super-compact synthetic insulation that’s compressed down to a third of its normal size, while retaining 80% of its thermal properties. And while insulated jackets are normally constructed with big puffy baffles to keep the insulation in place, the Race to Zero Puffer is built with continuous sheets of insulation anchored down with stitched bartacks to reduce weight, bulk and the potential for cold spots. The outer shell and inner lining are made from an ultra-lightweight, recycled nylon engineered to be the same thickness as silk. And the puffer weighs just 277 grams.

Vollebak started life on a run
While startups normally begin with two kids in a garage with a dream, the idea for Vollebak started life while we were running through the Amazon, Alps and Namib Desert. While surviving heatstroke, broken bones, bullet ants, angry snakes, tarantulas, hallucinations, and falling asleep while running, we decided that setting up our own company wouldn’t be so hard. We’d always have access to running water, a toilet and a bed. And we could try and tackle some of the challenges we’d faced. Today we make some of the most advanced gear on the planet. And it now includes the gear we’d loved to have raced in.
