Fabric Technology
 
Not sure which fabric you need or what the difference is between Gore-Tex and Pertex? The fabric you need will depend on the performance you are looking for and the conditions you are going to be wearing it in. Check out our handy benefits guide below to help you choose which fabric you will need...
  • Gore-Tex -  waterproof, breathable, and durable.
  • Pertex - windproof, breathable and water-repellent.
  • HyVent - waterproof, breathable, and durable.
  • Polartec - warmer, breathablehydrophobic.
  • Texapore - waterproof, breathable, and durable.
Rucksack Volume

The size and therefore type of rucksack that you will need is dictated by the amount of kit and clothing you will be taking with you. This could be anything from a bottle of water and some energy bars, all the way up to clothing, a tent, sleeping bags, food, and cooking equipment, to name just a few.

Below you can see a rucksack size guide to help you decide what size rucksack you will need. However, please note that the length of your trip is only the first part of choosing the right rucksack.

  • 10-30L = 0.5 day, Day hiking/Active use
  • 20-40L = 0.5-1 day, Extended Day Hiking
  • 40-60L = 2-3 days, Backpacking
  • 60+L = 4+ days, Extended Backpacking/Travel
Vibram

Vibram is a high performance sole, providing non-slip qualities, high abrasion resistance and durability.

Gore-Tex Technology

Gore-Tex is the benchmark for performance outerwear for decades. It refers to the use of a special microporous membrane (ePTFE), bonded to fabrics to make them durably waterproof but still breathable. A waterproof, breathable membrane full of microscopic holes, big enough to let moisture vapour escape but too small to allow liquid water through. This is then bonded to a layer of fabric which is in turn treated with a DWR to avoid the fibres themselves getting waterlogged.

Hydrostatic Head

Hydrostatic Head (HH) is the measure of how water resistant a fabric is. It is measured by the volume of water held in a tube over the fabric before it starts to seep through. The British standard for a fabric to be described as waterproof is 1,500mm/HH.

Season Rating

1 season = UK summer, +3°C

2 season = UK late spring/early autumn, +2°C to -2°C
3 season = UK early spring/late autumn, -3°C to -7°C
4+ season = UK/Apline Winter or cold climate expedition, -8°C to -12°C+

Jacket Fill Type
  • Down jackets offer the highest warmth to weight ratio of any insulation type. It’s obtained from geese and ducks, the smallest feathers found next to the skin. Generally speaking, goose down has a higher warmth to weight ratio than duck and compresses better.
  • Synthetic jackets contain man-made polyester strands that are used to imitate the air trapping down filaments to create pockets of warm air. These fibres are moisture resistant and retain their insulating properties when wet better than down.
  • Hybrid jackets are less common and more technical, they draw on the strengths of down and synthetic fills to maximise functionality and weight savings. They commonly use synthetic fill in the shoulders and arms of the jacket and down in the core body area. 
Jacket Technology

Waterproof or Windproof jackets do not allow any water/wind through. Resistant jackets are able to resist to a degree but not completely.
