It is important to wash your technical outdoor clothes regularly to keep doing what they are designed to do - to protect you against the elements. Follow carefully the washing instructions which you can find inside all our garments.
You should wash your diamondium products after approximately 150 hours of use. Your gear could be soaking up water just because it is dirty. Dirt attracts water so that it will mask Durable Water Repellency (DWR).
- Close all zippers.
- Wash at 40°C and use a mild detergent for technical fabrics (Nikwax, Grangers, etc.). Do not use fabric softener or bleach as they can damage the fabric's water-resistant properties and the fabric's color.
- Use water repellent spray or wash your garment with water repellent reproofing material (from Nikwax, Grangers, or other brands) if the garment no longer repels water.
- Tumble dry on low heat (some dryers have outdoor clothing settings). The heat helps to reactivate the waterproofing.
Besides making it clean again when it’s visibly dirty, washing a down jacket regularly has an important role in increasing its lifespan and maintaining its insulation properties.
- Wash at 40°C and use a down-specific detergent (from Nikwax, Grangers, or other brands). Do not use regular detergent as it will strip away the natural oils that down feathers have and make them more susceptible to moisture. Do not use fabric softener or bleach.
- Tumble dry on low heat with two clean tennis balls until completely dry. The tennis balls will help to distribute the down evenly. Every so often, remove the item, break up any clumps, shake it out to redistribute the down, and put it back in the dryer. Expect the process to take several hours and multiple cycles. No matter how tempting, don’t try to line dry or remove your down item before it is completely dry.
If don’t have a dryer available, you can air-dry your jacket by hanging it in an area that gets plenty of fresh air, and gently break up the clumps with your fingers as it dries. You can place it near a heater to help speed up the drying. Note that air drying is typically not recommended — it can compromise the loft of your down and take far too long to fully dry.
- Wash at 30°C with a gentle cycle and use the wool program if your washing machine has one. Do not use fabric softener or bleach. Use wool wash detergent.
- Flat dry in the shade. Do not tumble dry or iron.
