What is the Microlight Jacket?
The Microlight has long been the go-to choice for anyone needing lightweight, packable insulation in the mountains, but for this winter Rab have given it a complete overhall to celebrate its 10 year anniversary. You now get a jacket which includes every brilliant feature of the last generation, but with a completely new and improved fit, glove-friendly cuffs and a whole range of new colours.
What is the Microlight Jacket made from?
Outer fabric: The outer and inner fabric of the Microlight are made using Pertex Quantum. This tightly woven, water repellent fabric offers protection from the elements, so it’ll shrug off light rain and snow but it’s not waterproof! Please bear in mind that the fabric is lightweight so use your common sense; if you are going for a scramble or even thrashing about in the brambles, cover it with something appropriate, a shell jacket or lightweight softshell would be ideal. The Pertex fabric is also really slippy, so the Microlight will glide easily over or under additional layers, so it doesn’t restrict movement.
Insulation: Because the fabric is so light it allows the down inside to fully loft to ensure you get the most out of that luxurious insulation. Loft is a word used to describe the downs ability to expand, basically how “fluffy” it can become. The more “fluffy” down is the more warm air it can trap and the better it will insulate. The universal measure to determine how fluffy your jacket is called “Fill Power”. Technically speaking fill power is a measurement of the amount of space one ounce of down will occupy in cubic inches when allowed to reach its maximum loft. So, the Microlight has a fill-power of 750, which means that one ounce of that lovely RDS certified down will expand to fill 750 cubic inches of space. Basically, the higher the Fill Power the warmer a jacket will be. You may have noticed that I called the down “RDS” down, this stands for Responsible Down Standard, and means that the down comes from well cared for and happy geese As well as being fully RDS certified, each and every cluster of down has been treated with special Nikwax Hydrophobic stuff to ensure they resist moisture, retain more heat, loft better, and dry much quicker than untreated down. This does not in any way make this a waterproof jacket, so always carry a shell jacket…because it will rain!
What are the Microlight's features?
This is where we get to all the exciting new stuff, let’s start with the biggest improvement; it’s overall fit. The old Microlight Jacket was made by stitching the front panel to the back panel to create a simple 2-dimensional tube shape. This new version features a vastly improved 3-dimensional fit with the addition of side panels to create a body-hugging shape to ensure that all the lovely down insulation is as close to your body as possible to minimise heat loss. The more space inside a jacket, the less efficient the insulation will be; basically you’ll need to work harder to heat up the space as well as the insulation. With this new Microlight there’s still room to move around and add layers underneath, however the new shape is more efficient and more flattering…it just looks better!
For storage options, you get two nicely sized hand warmer pockets and a Napoleon pocket. Updated cuffs for this year ensure maximum insulation around the wrists yet allow you to fit bulky gloves comfortably underneath, a soft stretchy fabric cuff effectively seals in the warmth and keeps out the weather.
How does the Microlight Jacket fit?
As an insulating layer, it is designed to be a close, snug fit, yet features enough room to layer up underneath on the particularly chilly days. The rear of the jacket features a slightly dropped hem, while the new and improved fit means it wraps around the contours of your body far better than the old version.
Where does it fit in the layering system?
The Microlight is a lightweight, breathable and packable down jacket. Use it as an appropriate insulating layer depending on your activity level and the weather conditions. It works perfectly well as a standalone jacket on those crisp, dry, freezing days or as a cosy casual jacket. Layering is not a precise science and there is no one perfect system that will suit every person, situation or the weather conditions. Some of us feel the cold, others, like me, get hot very quickly, but for more advice on using layers please check outthis video.
