component waterproofing

This garment was approved in a shower test in 26 gallons of water/sqm/hour for 3 hours. This reproduces the conditions of a big mountain storm. Garment's waterproof properties linked to fabric used, watertight seams and assembly process .The seams of your MH500 jacket are 100% sealed.

Waterproof zippers

Waterproof zippers on main fastening and 2 outer hand pockets to guarantee the jacket waterproofing.

component breathability

To find out whether a fabric is breathable, we measure its evaporative resistance, or RET (based on the ISO 11092 standard). The lower the fabric's resistance, the more water vapor generated by physical activity evaporates, and the higher the fabric's breathability. For example: RET < 9 = extremely breathable fabric 920 = little or no breathability. Your MH500 jacket has a RET value of 6 (extremely breathable fabric).

Breathability of the garment

In addition to breathable fabrics, Quechua develops technical solutions (zippers, ventilation, mesh, etc.) to improve the overall ventilation of its trekking jackets and overpants (Forclaz, Bionnassay and Helium lines. These ventilation systems both allow temperature regulation inside the garment and help wick away perspiration generated by the body during exercise.

component with hydrophilic membrane

The component of your MH500 jacket consists of a membrane. A membrane like a very fine plastic film (polyurethane), making the component waterproof while remaining breathable. A membrane has the advantage of being softer, lighter, more durable and often more breathable than the coating. The coating is similar to a paint layer applied to the inside of the fabric. It is often less costly than a membrane and requires a lining for protection.

3-layer component

The MH500 jacket component is named "3 layer." The membrane is, in fact, bonded between the inner layer and the outer layer of the component (hence the name 3-layer component). This construction helps the membrane last longer and boosts the component's performance. In the case of 2-layer components, the membrane is bonded to the outer fabric only; the protective inner lining is free. This construction costs less but is generally more cumbersome.

Water-repellent component

A fabric is water-repellent when it allows water to slide over its surface without seeping in. This prevents the fabric from soaking up water and keeps it lightweight and breathable. A fabric becomes water-repellent by applying a treatment to its outer surface. This treatment must be renewed throughout the garment's lifetime (recommended after every 3 washes). All Quechua waterproof jackets have received a water-repellent treatment.

Additional recommended products

MH500 overpants protect the lower half of your body for a complete and effective rain protection system for your mountain outings. Care products: reproofing spray or liquid for use in the washing machine restores water-repellent properties of the fabric and optimizes the performance of your garment throughout its lifetime.
