How the Jacket Is Built for Hot Days Outside

Dual Fan Airflow

A hot trail or job site leaves a plain shirt sticking to you. Two brushless fan units at the waist pull air in and push it through the jacket while you keep moving.

Standard USB Power

Special battery packs add clutter to the pack. Kelvara plugs into any standard 5V USB power bank through the built-in port, so you can use one you already own.

Kelvara

Micro-Pore Fabric

A stiff work layer gets in the way when you reach, climb or carry gear. The lightweight, flexible micro-pore fabric lets the jacket move with you through the day.

Detachable Brushless Fan Units

A jacket with fixed electronics is awkward to clean after a muddy trip. Each 9cm brushless fan unit detaches from the jacket, so the fabric can go through the wash.

Kelvara: A Fan Cooled Jacket for Hot Workdays and Trails

Hot job sites and summer trails leave most people with a damp shirt and a water bottle as their only options. Kelvara is a fan cooled jacket with two brushless fans at the waist that move air through the jacket.

It plugs into any standard USB power bank through a built-in port, so no proprietary battery is needed. As an air cooling jacket, it offers low and high airflow settings. The lightweight micro-pore fabric is breathable, and the fan units detach so the jacket can go in the washing machine.

  • Two 9cm brushless fan units included
  • Built-in USB port for a power bank
  • Relaxed fit over a t-shirt or light base layer
  • Machine washable once fans and cable are removed

Outdoor workers and hikers can wear this fan cooled jacket over a t-shirt as a cooling jacket for summer days.
