The Rotor Vest uses the same PrimaLoft® Gold insulation as our sleeping bags, giving you an incredible warmth-to-weight ratio. At 128g the Rotor Vest is ideal as a layer to quickly throw on when you reach the tops or as part of a layering system in colder temperatures. Filled with 40g PrimaLoft® Gold with Cross Core with a wind and water resistant outer shell and lining for enhanced protection. With a half length zip, integrated stuff pocket (mesh backed so can be used for enhanced venting) and amazing pack size, this stripped back layer can be carried in the smallest packs.
PrimaLoft® Gold with Cross Core Technology is the highest quality synthetic insulation available. Providing warmth without bulk and insulating even when wet, it is the ideal fill for the typically mixed conditions found in the UK hills.
OMM insulation uses the same outer fabric from our wind stopper Sonic Jackets to provide wind and water resistance whilst retaining warmth. By blocking wind, we reduce the heat scouring effect that strips your hard won warmth away from the body.
Packs into its own pocket for compact storage. OMM insulation has the highest warmth-to-weight ratio for synthetic insulation by using the best quality PrimaLoft® combined with our ultra-lightweight outer layer.

What Insulation Do We Use?
OMM use PrimaLoft® synthetic insulation as it is widely regarded as the best quality available; with insulating properties very close to that of down plus largely manufactured from post-consumer recycled product (PCR). Usually manufactured in a roll or sheet of ‘wadding’, think loft insulation but a lot nicer! From PrimaLoft® we mainly use their Gold Eco with Cross – Core Technology, their highest rated and most sustainable option plus the latest ACTIVE fabric in the Core Ranges, built from a synthetic plume woven through a knitted mesh, CORE offers the warmth of a fleece but with less than half the weight.
How do I care for my Insulation?
Just like owning a top end sports car, a piece of performance Insulation is only as good as how well you care for it. In the same way a sports car still needs oil changes and screen wash, you need to regularly maintain your OMM Clothing to keep it performing at its best. It is important to follow the Product Care Instructions and use the correct wash and/or proofer product as these can affect your clothing’s performance. The benefit of using a synthetic insulation is it is much more resilient when washing plus dries a lot quicker.
How much insulation do I need?
That depends how cold you expect to get or perhaps you know you always run a little hot and so don’t need so much. The amount of insulation a product has, generally the warmer it will be. The amount of insulation in synthetically insulated products is quoted as per square metre. When using PrimaLoft® Gold Eco, the lowest value we use is 40gsm, up to 233gsm in our warmest Mountain Raid Sleeping Bag. We also use PrimaLoft® Active which is a much more breathable option as iti does not require the layers of fabric either side of it to stabilise the insulation. Though not as warm aas traditional options, the breathability and next to skin comfort makes it a great option.
What's the fit like?
Most OMM Clothing tends towards the “fitted” end of things. Designed for performance use, the fabrics often work best when dead air is reduced whilst also reducing drag and bulk when moving quickly. We use three different fits in our clothing ranges; Contact Fit, Fitted & Regular Fit. Most of our Insulation uses our Regular Fit, with a little more room and a squarer cut. You’ll find a link to the Fit Guide on each product page. You also find a link to our Size Guide, a more in depth table that shows measurement ranges for each size. Insulation should fit comfortably over a First & Mid Layer and are designed to work well with our Outer Layers.
