Core Neck Warmer



Stock Information

Scroll Location

Using our revolutionary Core fabric, constructed from PrimaLoft® ACTIVE, this is an incredibly soft and comfortable addition to your layering, perfect for sealing out cold air and keeping that hard earned warmth in. Great on cold runs and even better for a chilly overnight in your sleeping bag. Fast wicking and quick drying, the Core Neck warmer handles excess moisture with ease.
PrimaLoft® Active is built from a synthetic plume woven through a knitted mesh, offering the warmth of a fleece but with less than half the weight. With all the benefits of synthetic insulation, Core products work wet or dry with incredible wicking properties to ensure you won’t stay wet for long. Using the 75g/m2 weight of PrimaLoft® Active means 58% of the insulation is derived from recycled sources.

PrimaLoft® ACTIVE Insulating Fabric weaves PrimaLoft® fibres onto a mesh, giving a super high volume and open structure. Fabrics insulate by trapping pockets of air that the wearer’s heat cannot pass through. Core structure is exceptional at creating these pockets. However the openness also allows for a light breeze to disturb these air pockets and remove the insulation effect.


We always choose synthetic insulation over down to be sure that we can get warm even when everything is wet. We believe PrimaLoft® make the best synthetic insulation and so it is an easy choice for us. 75g/m2 PrimaLoft® ACTIVE uses 58% post-consumer recycled material, it is also bluesign and Oeke-Tex approved.


We can quote all the performance figures we like but what really sets the Core range apart is the sheer cosiness of it. Soft, fluffy, lightweight and an incredible insulator, it is unlike any insulation you’ve tried before.

What's the sizing like?

 You can find our Size Guide via the link on each product page, this includes measurement ranges for each size of hats & gloves. Our hats & gloves are unisex so it is often worth checking the size guide to ensure you get the right one. Some of our headwear is one size, this is because the stretch properties of the materials used allow it to cover a larger range. 

Can I return it if it doesn't fit?

 Yes! Our returns period is 14 days from receipt of the item. As long as the labels are attached, the clothing is unworn (except to try on) and the original packaging still intact (i.e. the clear poly bag it may have been wrapped in). Unwanted or unsuitable items are returned at your cost but exchanges are free to send back out. The returns address and details can be found on the packing slip included with your order. In case of a suspected warranty issue, follow the instructions on the packing slip or contact our support team: support@theomm.com

What materials do we use?

 We use a mix of performance fabrics in our hats & gloves that are designed to wick sweat and dry quickly whilst also being lightweight and low bulk in order to meet the demands of the mountain runner. For this reason, we do not use any cotton, wool (including merino) or leather. Most of our clothing uses variants of Nylon and Polyester. We then also include stretch elements such as elastane and chemical treatments (DWR) for water repellancy where needed. We work closely with manufacturers such as PrimaLoft to ensure we use the highest quality materials to achieve the best performance for the weight. 

Glove or Mitt?

 Both! well, maybe its not that simple. It depends on your priorities whilst running. Do you need to use your phone or touchscreen device? In which case go glove with e-tip. Or is warmth and weather protection the priority, in which case go for the Core Mitt and pair it up with the Kamleika Overmitt to seal out the bad weather. This is the warmest option from our range but it is also possible to pair the Kamleika Overmitt with a pair of gloves for the best of both worlds. A mitt will always be warmer than equivalent gloves, since your fingers are all in there together sharing their warmth!
