Rain Wear Guide

Having a comfortable piece of rain wear is imperative for enjoying the outdoors


When clothing gets wet, either from rain or condensation from sweat, it's not only uncomfortable but also a very serious issue, sapping the body of its warmth and strength, a dangerous condition better known as "hypothermia." This is why Montbell uses GORE-TEX® FABRICS and Montbell's proprietory DRY-TEC™ fabric in our rainwear. Using these two materials, we developed a wide range of products that not only allow you to comfortably enjoy the outdoors, but have the ability to protect you from the elements and move moisture outside of the garment.

Made with GORE-TEX® Fabrics, which offers world's class performance in waterproof/breathability in a super lightweight, compact package. Constructed with attention to the last detail with waterproofing and water repellent treatments in order to maximize functionality, including processes to prevent water retention at the joints of the cuffs and hems. Weight reduction measures include Smart Sewing (jacket only), minimization of sewn parts, and reductions in the width of seam tape. Offers outstanding performance for high momentum activities such as mountain climbing and speed hikes.

K-Mono Cut


K-MONO CUT reduces the amount of seam lines eliminating areas where water can penetrate, promoting the jacket to be waterproof and lightweight. This innovative pattern is based on Montbell's philosophy of "Ki-no-bi" which is a Japanese term for "Function is Beauty".

Waterproof


Reducing the amount of seam lines eliminates areas where water can penetrate the jacket.

Lightweight


Minimizing the amount of seam lines and tapes reduces the jacket's final weight.

Denier


Denier is the weight of a 9,000m long thread, and in practical terms it is a good equivalent of thickness. A thread of 1-denier would weigh 1 gram. The higher the denier the thicker the thread becomes and in turn has stronger abrasion and tear resistance. Thicker threads are commonly used for reinforcing areas that are exposed to friction, like edge guards. On the other hand, materials that are made with thinner denier threads feel smoother and are better suited towards clothing.

3-layer, 2.5-layer, and 2-layer products. What's the difference?


Waterproof fabrics all share a common trait of being made with a waterproof membrane. Since the membrane is delicate and easily damaged, it is usually laminated to layers of fabric for protection. For example, a 3-layer fabric is made by laminating a membrane to an outer and inner layer of fabric. This sandwich of outer fabric, membrane, and inner fabric give the materials its 3-layer name. As its name would suggest, a 2-layer fabric is made by laminating the membrane to only an outer fabric. Although lightweight, this comes with a tradeoff of exposing the membrane. Montbell products made with 2-layer fabrics receive a special coating on the inside of the product or are lined with mesh or taffeta to protect the membrane. On the other hand, 2.5-layer fabric is made by laminating the membrane to an outer layer of fabric and then the membrane receives a special dot-print coating that protects the membrane and prevents it from coming into contact with skin or your clothing. It's not quite a 2-layer and isn't quite a 3-layer, hence the 2.5.

Waterproofing

--- Stopping water from getting in ---

Waterproofing is a measure of the ability to resist pressure from external moisture trying to permeate into a material. This property can be described with a numerical value that measures "water pressure resistance." Water pressure resistance is measured by placing a column of water on the outside layer of a material and applying pressure until water begins to seep through, at which point the height of the water is measured in millimeters.

Breathability

--- Allowing trapped moisture to escape ---

Is a high level of water resistance the only feature your hard shell needs? Vinyl raincoats certainly have a very high degree of water resistance, but they cannot release heat or water vapor that builds up inside. Similar to windows on a cold winter morning, water vapor can cool and condense into water droplets on the inside of your jacket. So even if your hard shell is able to protect you from external moisture, if it can’t release water vapor, you can still get wet from internal condensation.

Breathability refers to a material's ability to release built up water vapor. GoreTex Fabrics and other membranes make this possible by keeping water from getting in and allowing water vapor to get out. Membranes can do this because liquid water molecules (rain) are larger than vapor molecules (evaporated sweat), which allows vapor molecules to escape through the membrane's microscopic openings. (left figure, excluding certain materials.)

  • Montbell's Rain shell jackets are tested by JIS L-1099 B-1 Method when measuring breathability.

Smart Sewing


Seam weight and bulk is reduced by the use of Montbell's Smart Sewing. This labor intensive technique produces a reliable sewn seam while eliminating bulk by trimming excess fabric left in traditional methods. A low volume seam makes for lighter garments, better layering & improved comfort.
