OMM garments are designed to provide exceptional weather protection and breathability. Routine product care and maintenance ensures the optimum performance of your OMM garment. Build-up of dirt and other surface contaminants such as body oil, salt, sunscreen and sweat can reduce the effectiveness of the textile’s durable water repellent (DWR) treatment, affecting performance and breathability. Dirt allows water molecules to be drawn into the face fabric, saturating or ‘wetting out’ the fabric and leading to increased levels of condensation on the inside of the garment. Oils can have a degrading effect on the fabrics and treatments while salt and debris can act to abrade membranes and fibres over time. Properly washing your OMM product removes dirt and other contaminates from the garment, restoring its water repellency and breathability




To prepare the garment for washing; close the main zippers, open pocket zippers, and release tension on all elastic drawcords.




For any technical fabrics, including Kamleika, PointZero H2O or any others from our range, we ONLY recommend using a cleaning agent made specifically for performance fabrics. Outdoor speciality retailers carry various brands. We recommend Grangers Performance Wash. These specialists washing agents are designed to be gentle and to rinse completely. Detergent residues can contaminate and impair the function of the membrane fabric and its water repellency treatment. When using washes specific to outdoor apparel, simply follow the instructions. Conventional detergents contain fragrance, colorants, optical brighteners, enzymes, surfactants and fabric softeners that will hamper garment function and potentially cause damage.




DWR is a polymer applied to the face fabric of an OMM garment. When the garment is not shedding water like it used to, even after it’s been washed and dried, it’s time to reapply the DWR. We recommend using Grangers Performance Repel. After washing, close all zippers, hang the wet garment on a hanger and spray DWR evenly and generously onto the wet face fabric of the garment, concentrating on areas of high wear such a the waist, shoulders and sleeves or where you have noticed a particular drop in the beading effect. Next, place the garment in a tumble drier on a low heat setting (~30°C /104°F) for up to 15 minutes, not to dry it completely but to gently apply heat. You may also use a wash-in DWR, which can be as effective but do not allow for concentrated application in key areas and will be applied to the inside of the jacket (though this will wear off with use).

2-in-1 Wash & Proof are also a good option if you find you are washing and proofing very regularly, perhaps if training solidly over winter or for outdoor professionals who spend every day in their waterproofs!

If you do not have a tumble dryer, hang the garment somewhere warm such as above a radiator (though not on or in contact with). The application of heat helps bond the chemical treatment to the fibres.



When to wash depends on how often and how hard you use your gear. For heavy activity we suggest washing after every 10 to 12 days of use, and for light activity wash every 20 to 30 days of use. Use your best judgment; if your garment looks dirty, or you are starting to feel damp or clammy, or your garment is no longer shedding water and is wetting out, it’s time to wash it. Take care of your gear and it will take care of you.





We strongly recommend washing your insulated jacket in a FRONT LOADING washing machine. Select the gentle cycle with a two-rinse setting and a wash temperature of 30°C / 86°F. Tumble dry your garment inside out on a medium (60°C/140°F) temperature setting for approximately 15-20 minutes then air dry. To remove stubborn stains, first, spot clean the stained area with Grangers Performance Wash, allowing the stained area to soak for 10-15 min, or use a stain eraser on the contaminated area. Then wash and dry the garment as per the instructions given above.


How to wash your Core garment


You can wash your core garment in the washing machine with your regular clothes, however, be wary of other garments with velcro or sharp components such as jeans buttons, metal toothed zips etc. as these can snag the fabric. In this case it’s best to put the Core garment inside a mesh laundry bag (for delicates and sportswear). Always turn the garment inside out for washing. It’s best to wash it with other soft clothes and sportswear if possible. 


Choose a wash temperature of 30°C or lower. You can use your regular laundry detergent or a tech-wash, but do not use fabric softeners or fragrance boosters. Core garments are safe to use with antibacterial laundry sterilising fluid (follow the product instructions for dosing). The garment will be almost dry after the spin cycle, so it’s best to dry naturally. However, if you choose to tumble dry, you can do so on a low heat setting and remove when still very slightly damp.



The best way to wash your pack is simply with water. You can either rub the dirt off with your hands or else you can scrub the pack with a soft brush. You should be able to get most of the dirt off this way. If you feel that you need to use soap, use a mild or pure soap or else an outdoor wash such as Grangers Performance Wash and rinse the pack thoroughly to remove any residue. Hang the pack to dry (don’t use a dryer or any other source of heat). If you hang the pack outside, leave it in the shade. It should dry overnight, but it might take longer depending on the climate. Remove the back pad before washing to speed up drying time.
