WASH & CARE INSTRUCTIONS FOR YOUR BLACKYAK PRODUCT

Blackyak products are developed using a range of technical materials. To allow your garment to function perfectly it is essential that the material is clean and has been properly maintained. Dirt, oil, salt and other invasive elements will impair functions, such as breathability, insulation & water repellancy. We suggest that you care for your functional clothing by washing it regularly and by following our simple instructions. We will show you how to care for your BLACKYAK products so that they perform perfectly for you, when you need them to.

WASHING INSTRUCTIONS

MERINO

Merino wool cools, warms, prevents strong odors, is soft and light. In addition, the care of the natural material is simple. In order to guarantee the longevity of the product, a few things should nevertheless be observed when washing.

WASHING

1 Close the zippers and turn the product inside out.

2 Use wool detergent (pH-neutral, without protease).

3 Normal wash cycle at 30° Celsius | 86° Fahrenheit

Warning: Do not use fabric softener or bleach!

DRYING

1 Air dry.

Warning: Do not dry the tube!

GORE-TEX® INFINIUM™

The comfort and function of GORE-TEX INFINIUM™ are well balanced. This ratio can be affected by permanent external influences such as fats, salts or other dirt. The care of the products ensures balance and full functionality.

Washing

1 Place the product in the washing machine with zippers closed, hook-and-loop fasteners loosened, and drawstrings loosened.

2 Do not wash together with other heavily soiled laundry.

3 Use liquid detergent for functional textiles.

4 Wash on a gentle cycle (max. 40 °C).

5 Rinse twice.

6 Spin at the lowest possible speed.

Warning: No fabric softener, no powder detergent, no stain remover, no bleach.

DRYING, IRONING & WATERPROOFING

1 DRY Air drying alternative: dry in dryer at warm temperature and low speed.

2 IRONING Alternatively to the dryer, the impregnation can also be reactivated by ironing (warm, without steam). Products with a permanently water-repellent surface must not be ironed! Place a cloth between the garment and the iron.

3 IMPREGNATION GORE® WINDSTOPPER®: If water no longer beads off, re-impregnate. Permanently water repellent surfaces: Wash and rinse twice. Do not reimpregnate

Warning: Do not dry hot.

GORE TEX®

High performance equipment requires regular care to ensure that all functions are fully maintained and that the longevity of the product is guaranteed. Because sweat, grease, oils and dirt reduce the range of functions. Therefore, all GORE-TEX® – GUARANTEED TO KEEP YOU DRY™ products should be washed and dried regularly. This ensures that no rain can penetrate even during the next use.

WASHING

1 Place the product in the washing machine with zippers closed, hook-and-loop fasteners loosened, and drawstrings loosened.

2 Do not wash together with other heavily soiled laundry.

3 Use liquid detergent for functional textiles.

4 Wash on a gentle cycle (max. 40 °C).

5 Rinse twice.

6 Spin at the lowest possible speed.

Warning: NO FABRIC SOFTENER, NO POWDER DETERGENT, NO STAIN REMOVER, NO BLEACH

DRYING, IRONING & WATERPROOFING

1 DRYING After air drying, tumble dry for 20 minutes. This reactivates the permanently water-repellent impregnation of the upper material.

2 IRONING Alternatively to the dryer, the impregnation can also be reactivated by ironing (warm, without steam). Place a cloth between the garment and the iron.

3 IMPREGNATION If the impregnation can no longer be activated by drying, it is advisable to apply a new impregnation.

DOWN

In order to maintain the insulating effect of the down in a product, it should be washed regularly. Wet and clotted down lose their bulking power, and thus their ability to store warm air. If lumps of down can already be seen from the outside or if an unpleasant odor can be detected, the down product should be washed.

That's how it works:

WASHING

1 Place the product in the washing machine by itself, with zippers closed, turned inside out, and with four down wash balls (alternatively tennis balls).

2 Use a special down detergent!

3 Wash on a gentle cycle (max. 30 °C) followed by a spin cycle.

4 Run an additional rinse cycle to remove all detergent residues.

5 Drying

Warning: no heavy-duty detergent, no fabric softener

DRYING

1 Place the product in the dryer separately from other laundry with four down wash balls (alternatively tennis balls).

2 Tumble dry for 60 minutes at 60 °C.

3 Allow to cool for at least 1 hour and shake occasionally.

4 Tumble dry again for 60 minutes.

5 Let the product cool down and check for residual moisture while cold.

6 If necessary, repeat the drying cycle.

Warning: do not air dry.

SYNTHETIC INSULATION

Every functional garment loses its performance through intensive use. Accordingly, garments should also be washed with synthetic insulation. The principle of regularity is as follows: as rarely as possible, as often as necessary. Sweat stains, dirt, odor and the way in which the product is used give information about when the product should be washed.

WASHING

1 Close zippers, loose velcro fasteners and drawstrings

2 Place the product in the washing machine turned inside out.

3 Use detergent for functional textiles (ideally a 2-in-1 wash-in waterproofing treatment).

4 Wash on a gentle cycle (max. 30 °C) followed by a spin cycle (max. 800 rpm).

Warning: no fabric softener, no bleach.

DRYING

1 Air dry, shaking regularly.

2 Dry in a dryer - at medium temperature in a gentle program with down washing balls (alternatively tennis balls)

Warning: Do not iron, do not steam, no direct heat.
