Down Parka Jackets & Fill Power

When the weather starts to dip and the icy mornings start to roll in, the need for an insulated down parka jacket becomes a necessity.

What is an Insulated Jacket?

Insulated jackets are jackets that are filled with an insulting material to essentially keep you warm and reduce the amount of heat that your body loses in weathered conditions. There are three main types of insulated materials which include synthetic insulation, down insulation or a combination of them both. Insulated jackets are perfect for extremely cold temperatures but they aren’t too great in the rain, dense rainfall will slowly deteriorate the insulating properties – that’s just to bear in mind. We suggest keeping or carrying a light waterproof in your car or bag because as we all know, the weather in the UK can be pretty unpredictable.

Insulated jackets have changed over the years, the first insulated jackets that came out were so thickly insulated that you would find it hard to move or even bend down. (Google the Michelin Man for a visual) Over time and with advanced technology, insulated jackets today are packed lighter with various layers of different weights which makes them lightweight and wearable.

Synthetic vs Down – What are the Differences and how to Choose Between Them?

Synthetic is a material that is man-made which contains polyfibres to echo the properties of down. This is often a popular choice for people who don’t wish to use anything derived from animal products. That takes us to down, down comes from birds – either duck or goose which is commonly used within clothing products. The feathers are light and fluffy and once compacted together they create a plush pillow of warmth to sandwich in-between the chosen nylon or polyester fabric. Both materials have their pros and cons.

Synthetic insulation is commonly picked over down for the lower price however, the loss of heat is quicker than a natural down jacket. In terms of handling moisture, synthetic will dry much quicker if it gets wet and is easier to clean and care for. However Nature’s best insulation down, is lighter and will keep you warmer for longer. Down is also extremely compressible – when you’re pondering on what to take for a long weekend away, you will be surprised as to how small you can fold a down jacket to fit into your holdover bag so it’s definitely worth taking.

You also need to take into consideration where you will be wearing the jacket. If you are walking the dog or hanging out with friends at the park, down jackets are ideal as these are low-intensity activities. If you are exercising or doing high-intensity activities, the down will be far too warm and you will be better off with a lighter polyester fleece or finely knitted material.

What is Fill Power?

Fill power is the amount of down within the product. The higher the fill, the more air a certain weight of the down can trap and the more insulating ability the down will have. Fill power ranges from about 300 for feathers to around 900 for the highest quality goose down. This is determined during the manufacturing process where the down is sorted, washed and sterilized and a stated number is given. Trespass Top Tip – keep an eye out for this number when purchasing your down jacket as it will give you an indication of the power.
