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. 

 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

 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. 

 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!
