CHAPTER 1 

Why Outerwear Technology Matters 

 Whether you’re aware of it or not, the fabric, technology, and design behind your outerwear directly affect your experience on the mountain. 

 For a mountain athlete, your outerwear should: 

  •  Help your body ventilate during periods of high exertion 
  •  Keep you warm and dry while sitting on the lift or waiting to race 
  •  Be able to withstand prolonged exposure to inclement weather, high elevations, and extreme temperatures 
  •  Enable your full range of movement and give you the comfort and flexibility you need to perform at your best 
  •  Be durable enough to withstand the wear and tear of multiple ski seasons without losing its performance edge 
 It’s easy to tell if your current gear is limiting your comfort, restricting your movement, or just getting in the way of your performance. It’s much more difficult to determine what outerwear specs and features to look for to solve those challenges. 

 As you research and compare different outerwear options, it pays to be informed. In this guide, we’ve outlined everything you need to know about outerwear fabrics, technology, and design in order to identify the best value and the best performance outerwear for your unique needs.

CHAPTER 2

Waterproofing Technology Basics

When fabric gets wet, it loses its breathability, insulation, and flexibility—all things that affect your comfort on the slopes. Waterproofing technology is designed to prevent moisture from saturating outerwear fabric and keep your gear performing as intended.

Not all waterproofing technology is created equally. The secret to staying dry, warm, and comfortable on the mountain comes down to three distinct features.

1. DWR Treatment

When you watch water bead off your jacket rather than sink into the fabric, you’re witnessing durable water repellent (DWR) in action. DWR is a water-resistant coating that’s applied to outerwear fabrics to prevent garments from “wetting out”—a term that aptly describes what happens when your jacket soaks through and instantly loses its breathability and insulation properties.

In addition to repelling falling rain and snow, DWR is the first line of defense against moisture that’s applied with pressure. When you’re sitting on a lift, your entire body weight is pressing against the chair and pushing moisture into your ski pants and jacket. DWR is designed to stand up to this extreme pressure and prevent water from penetrating into the fibers of the fabric.

DWR is often applied to fabrics that have been specially designed or treated to be water-resistant. These fabrics are the specialty of industry-acclaimed brands like Gore-Tex, but the same technology is also available in non-branded forms.

2. Waterproof Membranes

If DWR is the first line of defense against moisture, waterproof membranes are the second string. Without this thin, plastic-like film, a garment may be water-resistant, but it won’t be truly waterproof.

Membranes are typically used in performance outerwear in three ways:

  • As an outer shell: Waterproof membranes can be laminated and applied to the outermost layer of a garment, creating a hard shell.

  • As an inner layer: When placed between the insulation and the outermost layer of fabric, waterproof membranes stop moisture from seeping into the insulation layer.

  • As a liner: A waterproof membrane prevents water vapor like sweat from penetrating the garment from the inside out.

Together with DWR, this three-level membrane combination provides the highest degree of waterproofing possible for high-performance outerwear.

PTFE

Although waterproof membranes are intended to keep you dry, some types are known to hinder breathability. If you find yourself zipping and unzipping your jacket as you break a sweat on the hill, then your outerwear membrane probably isn’t made of polytetrafluoroethylene (PTFE).

PTFE is the most advanced waterproof membrane on the market. Unlike its predecessors, PTFE is exceptionally thin, flexible, and porous. The pores are small enough to prevent liquid like melting snow, sleet, and rain from penetrating the membrane, but big enough to allow water vapor (i.e., sweat) to escape. Because PTFE doesn’t require additional lamination as an outer layer, it’s also exceptionally breathable, flexible, and light.

3. Seam Sealing

On a basic level, the more tiny holes that exist where the fabric has been sewn together, the more opportunities exist for moisture to pass through.

To eliminate this risk, garment seams can be reinforced with a sealant or seam tape. Oftentimes, only the critical seams (areas that are most vulnerable to moisture penetration) will be sealed. On a jacket, critical seams include the shoulder, armhold, and hood back yoke. For pants, critical seams usually refer to the knees, ankles, and rise.

CHAPTER 3

Insulation Technology Basics

Outerwear insulation falls into two general categories: down or synthetic. Below, we’ve outlined the pros and cons of both types.

Down

Down is typically made of duck or geese feathers and is known for being extremely warm, lightweight, and compressible. If down gets wet, however, it instantly loses all its insulation properties. To remedy this risk, down can be treated with DWR to heighten its water-resistant properties. DownTek is an example of a DWR-treated down brand.

Down jackets will typically be given a power and a weight rating. Power refers to the resistance of the feather to pressure. Higher-quality down that uses fewer quills and more plume will have a higher power rating. It will also provide more loft with less fill.

Weight refers to the amount of fill used in the garment. Together, the weight of a garment and the quality of the down impact its warmth, compressibility, and breathability.

Synthetic Insulation

There are two main types of synthetic insulation available: rolled and blown. Rolled insulation is more common due to the fact that it’s cheaper and naturally more water-resistant than down or blown synthetic alternatives. That said, rolled goods don’t stretch or flex well. They also tend to be dense, heavy, and stuffy.

In contrast, blown synthetic insulation is much less dense, allowing more air and water vapor to permeate through the garment. Blown insulation offers superior stretch and flexibility, improving your range of movement on the hill. To achieve two- or four-way stretch in an outerwear garment, using blown insulation or a down/synthetic blown blend is a must. PrimaLoft is a well-known synthetic blown insulation brand that offers both a synthetic down blend (half down, half blown synthetic) and a fully synthetic down (100 percent blown insulation).

In addition to the type of insulation used, there are a handful of other factors that dictate how warm you feel in your outerwear, including:

  • Waterproofing and breathability

  • The amount of insulation used

  • Layering (what you wear underneath between your skin and your outermost layer)

  • Seams (whether or not they’re sealed)

  • Garment care

Dirt and oil can get into the pores of outerwear fabric, affecting its breathability and abrading the DWR treatment. To ensure your gear continues to perform up to par each season, make sure you’re giving it the right kind of TLC. Follow the care instructions included on the tag!

CHAPTER 5

Identifying the Right Fit and Design

As a mountain athlete, maintaining your range of movement on the hill is paramount. To bend into a tuck, ski rough terrain, buckle your boots, or simply sit on the lift, you need outerwear that’s specifically designed to bend, stretch, and twist with your body.

The best outerwear is reverse-engineered with those movements in mind. To identify outerwear with a performance-centric design, seek out answers to the following questions:

1. Can You Lay Your Jacket Flat?

Jackets that are designed to bend at the elbows and twist with your body shouldn’t be able to lie perfectly flat. If you lay your jacket out on a table and it forms a perfectly level plane, it’s a telltale sign that it wasn’t designed with your movements in mind.

2. Does It “Lift”?

“Lift” is when you raise your arms and the bottom hem of your jacket rises a couple of inches. The right design elements and materials can prevent lift and enable your full range of movement without compromising your comfort. For instance, ski jackets that are designed to have less fabric at the inner elbows make it easier to grip ski poles or bend forward into a tuck.

In ski pants, lift can occur around the ankles and in the rise as you bend your knees or lean forward. An articulated knee and a multidirectional stretch fabric will prevent your pants from pulling against you or riding up as you lay down a turn.

3. Is It Flexible?

In the past, the only way to guarantee sufficient waterproofing and insulation was to use thick, inflexible fabric. With modern advances in fabric technology and DWR treatments, it’s now possible to find gear with two-way, four-way, or even 360-degree stretch. In other words, you shouldn’t need to sacrifice mobility in order to stay warm and dry on the slopes.

4. Are the Pockets Easy To Access?

When you spend hours on the mountain training for a race or making the most of a powder day, little features like pockets suddenly become more important. As you compare different jackets and pants, don’t forget to look at pocket placement and size. Can everything you’d like to keep with you fit comfortably into the pockets? Are they convenient to access from both a standing and a sitting position? It helps to know the answers before you need them.

5. Is It Built To Last?

If you’re going to spend a little more on your outerwear, you need assurance that it will stand up to multiple seasons of use. As you compare your options, look for information on how long the DWR treatment is designed to last, what type of conditions the garment is built for, and what type of care it requires on a yearly basis. Choosing outerwear with a flexible, stretch fabric will limit your risk of tearing or ripping due to normal use.

As you choose between ski pants, check to see if they’re equipped with scuff guards along the inner leg to prevent ripping, tearing, or abrasion. To truly improve the longevity of the product, scuff guards should be made of a stronger, more cut-resistant fabric than what’s used elsewhere on the garment.
