What are the Mythic Shorts?
They're lightweight and packable insulated shorts that use 800FP European Goose Down for a boost of warmth when the pace slows. They're ideal for winter belaying, mountaineering, climbing, or setting up camp at high altitudes.
What are they made from?
Insulation: The Mythic Shorts are filled with 74g of 800FP European Goose Down with a Fluorocarbon-Free Hydrophobic finish, with PrimaLoft® Gold Insulation used across the seat for improved weather resistance.
European Goose Down is fantastic quality down - it has larger clusters than Duck Down which improves the warmth to weight ratio. These clusters are made up of tiny feather strands that trap heat. The down is treated with a fluorocarbon-free hydrophobic finish, which adds light water resistance to the down itself. This helps the down maintain its thermal performance in damp environments, as it's no secret that down and moisture don't like each other!
Rab has used PrimaLoft® Gold Insulation across the seat to ensure optimal thermal efficiency even when wet. PrimaLoft® Gold is a cosy and breathable synthetic insulation that's highly efficient with low bulk and weight. The small fibres of this insulation provide excellent thermal efficiency; they're thinner than human hair, and the thinner the fibres, the warmer the insulation will be.
Can't quite catch the lingo? Here's a quick break down.
Fill power - Fill power measures the warmth and efficiency of the down, alongside its ability to loft/fluff up. A rating of 800 fill power means that 1oz of this down fills 800 cubic inches of space when fully lofted.

R.D.S - The Responsible Down Standard ensures that the down is sourced from happy birds who haven't been plucked and have been well cared for.
Hydrophobic - Hydrophobic down dries out and lofts quicker, resisting moisture from sweat that may build up as you warm up inside the jacket. Fluorocarbon free Hydrophobic finishes don't use harmful chemicals that cause damage to the environment and our ecosystems.
Fabrics: Rab has used 20D Pertex® Quantum Pro for the jacket's outer and 10D Pertex® Quantum nylon ripstop for the lining for maximum loft and protection from the elements.
Pertex® Quantum fabrics are created from recycled materials and use tightly woven fibres for excellent wind resistance and durability whilst still being lightweight and soft. They are designed to perfectly balance wind resistance and breathability, providing the ultimate performance for intense mountain missions.
The Pertex® Quantum Pro outer has a microporous coating and is treated with a fluorocarbon-free DWR (durable water repellent) that encourages rain and snow to bead off the material instead of soaking in, to provide excellent water resistance, making it more suitable for use in cold or damp environments where keeping warm and dry is crucial. However, please note this does not make the shorts waterproof.
The Pertex® Quantum lining is effective at trapping still air, helping to warm the insulation and maintain its efficiency whilst creating a light, protective barrier from the elements.
What are their features?
The shorts feature a comfortable waistband with dual hook and loop waist adjustments to allow you to cinch them in and enhance fit over various layers and trouser styles.
Full-length one-way YKK® side zips allow quick and easy on-offs without having to remove your boots, reducing time spent faffing in the cold.
A relaxed fit, coupled with precurved knees provide a natural, unrestricted range of movement, offering flexibility for various tasks such as bending down and crouching when setting up basecamp.
The shorts feature a stitch-through baffle construction, which helps reduce weight and increases packability, whilst also helping to further improve mobility.
Once you're down with the shorts, you can quickly pack them away in the provided lightweight stuff sack, allowing them to take up minimal space in your pack, ready to be deployed when the pace slows.
