Fabric choices | About Repack


Born out of years gunning down a muddy trail. We knew that what we wore could make or break a ride. Sick of the market choices, we decided to try and break the mould with some simple material and design choices.


Back in the 70’s a small group of californians started a new craze – riding their bikes offroad on the local mountains. Standard street bikes were soon modified into ‘klonkers’. In the early days of mountain biking, they started competing these klonkers on a downhill trail. The traditional hub brakes got so hot that by the time they made it to the finish line all the grease had melted and the hub would need repacking – hence the trail was named ‘Repack’. The original core included Charlie Kelly, Joe breeze, Gary Fisher and Thomas Ritchey. For further info check out Charlie Kellys site.

Merino / Bamboo Charcoal

Bamboo charcoal is made up of pieces of bamboo, which are taken from plants five years or older and burned inside an oven at temperatures over 1000°C. It not only provides a new way to utilize bamboo, but also benefits environmental protection by reducing pollutant residue. Bamboo charcoal is an environmentally functional material that has excellent absorption properties. Bamboo charcoal has a long history in China and has been documented as early as 1486 AD during the Ming Dynasty.


Bamboo charcoal is made of bamboo by means of a pyrolysis process. According to the types of raw material, bamboo charcoal can be classified as raw bamboo charcoal and bamboo briquette charcoal. Raw bamboo charcoal is made of bamboo plant parts such as culms, branches, and roots. Bamboo briquette charcoal is made of bamboo residue, for example, bamboo dust, saw powder etc., by compressing the residue into sticks of a certain shape and carbonizing the sticks. There are two equipment processes used in carbonization, one is a brick kiln process, and the other is a mechanical process.


Bamboo contains many pores in its structure, controlling temperature, and voiding moisture.


The many pores in its structure also make it excellent for absorbing odor-causing chemicals.


Naturally biocidal, and safely inhibits the growth of bacteria and fungi.

Non Static

As bamboo-charcoal nano particles are conductive, their presence in the fiber helps prevent charge buildup. Berino products will not give static shocks even in dry conditions.

Emits Far Infrared Energy

Far-infrared energy penetrates beyond the skin level and is absorbed efficiently by cells below. Near-infrared is mostly absorbed at the skin level and raises the skin temperature. Far-infrared rays can penetrate up to 4 centimeters (about 1-1/2 inches), exciting the vibrational energy of molecules and resonating with cellular frequencies – as a result, FIR rays promote bioprocesses such as increased metabolism and blood circulation.


Bamboo charcoal is known to have high porosity. Various impurities or foreign matter will be absorbed over the wide surface area of the charcoal. When air passes over, if the humidity is high, the charcoal will adsorb the moisture and the air will be converted to dry air. If the air is too dry, then the charcoal will discharge its own moisture, thus adjusting the humidity in the air.
