Introduction
Ultralight mittens born from surplus fabric
The UL Mittens are ultralight and easy to carry with only 19g in weight. They were born out of an idea to reuse surplus fabric from the UL All-weather Hoody.
Although they are not completely waterproof since the stitches are not seam sealed, the fabric itself is wind/waterproof and will serve you as functional rain mittens or wind-protection gloves.
*For seam sealing instructions, please refer to the Instuction section down below.

Material
Pertex Shield Air
The Pertex Shield Air is a novel fabric developed by Pertex to further improve water pressure resistance, washing resistance, and overall quality from existing nanofiber membranes.
Nanofiber membranes are net-like structures made of extremely fine polyurethane (PU) fibers that are water repellent (hydrophobic). They have a sponge-like structure with many micropores, allowing the air and moisture to pass through. This air-permeability creates exceptional comfort within the clothes.

The Pertex Shield Air is much lighter than conventional nanofiber fabrics, with a weight of 50g/㎡ to 60g/㎡. For breathability and durability, our proprietary version of Shield Air has 15 denier nylon fabric (40 denier ripstop) as the outer layer and 7 denier nylon as the inner layer. This combination makes it much lighter and more breathable than other nanofiber-based, waterproof moisture-permeable fabrics.

Notes before use
- Not completely waterproof.
- The UL Mittens are made of our ultralight water-resistant, ultrathin, water-permeable fabric. Please handle them with care as they can be torn or ripped when rubbed against rocks or poked by branches.
- The UL Mittens are comfortable when you are on the move in a relatively warm environment. However, it is less warm than normal gloves so we strongly recommend you wear wool inner gloves to keep you warm especially when severe weather is to be expected.
- In order to maximize the moisture-permeability of the two materials, after-use care is necessary. The performances of the membrane, facing and lining can be impaired by dirt, sweat, skin oils, or other substances. Please follow the washing instructions of each product to properly wash, dry, and keep clean. The use of rainwear-specific detergent is highly recommended. The water-permeability is hindered as the water repellency is declined. The water repellency can be restored by applying the heat of a tumble dryer at low-temperature or a hairdryer. Use of a water repellent agent is recommended if it is not restored by the heat of the dryer.
- The Pertex Shield Pro uses ultralight and thin microporous material. Vaseline, insect repellent, and ethanol-containing substances such as hair creams, cosmetics, and sunscreens may stain the fabric. They may also hinder the water-permeability of the fabric.
Seam sealing
The UL Mittens are made of waterproof material. However, to make your Mittens fully waterproof, the seams must be sealed by yourself.
