When choosing outdoor gear, you’ll often see labels like “water-resistant” or “waterproof.” While they sound similar, the difference between the two is critical, especially in winter. At Wintergreen Northern Wear, we prioritize breathability because, for active winter adventurers, staying dry from the inside can be just as important as shedding snow from the outside.

The Physics of Staying Dry: Precipitation vs. Perspiration
Most people think of staying dry as avoiding precipitation. But the moisture that builds up inside your gear, your own perspiration, can be the greater danger in winter. If sweat can’t escape, it condenses on your skin or in your layers, eventually freezing. That moisture robs heat from your body, and what begins as damp discomfort can escalate to frostbite or hypothermia.
While excellent at blocking outside rain, waterproof fabrics often trap sweat inside. Breathable fabrics, on the other hand, balance weather protection with the ability to vent body heat and moisture.
Wintergreen’s Choice: Supplex® Nylon with DWR
Our gear is designed for active winter use; skiing, dogsledding, chopping wood, hiking, or just chasing kids around the sledding hill. For these activities, breathability is essential.
That’s why we use Supplex® nylon treated with a Durable Water Repellent (DWR) finish:
-
Water resistant: DWR causes water and snow to bead up and roll off the fabric.
-
Breathable: The fabric itself allows moisture and heat to escape.
-
Durable: Supplex® is tough enough for decades of outdoor use, resisting abrasion and wear.
Our Shell Anoraks, Shell Pants, and Wind Shirts all use this formula because it works for real winter conditions.

Limitations: What It’s Not
We’re transparent: our garments are not fully waterproof. Seams aren’t sealed, which means sustained heavy rain or prolonged wet-snow pressure can eventually seep through. For all-day downpours, you’ll want true rain gear. But keep in mind, rain gear sacrifices breathability, and condensation will likely build inside.
For typical northern winters, cold, dry snow, high exertion, our system is the best balance.
When Waterproof Makes Sense
Fully waterproof shells have their place: multi-day rain treks, wet-snow slogs, or non-active scenarios where you’re standing still in prolonged precipitation. But for active winter adventurers, they’re often overkill. The breathability trade-off can actually make you wetter from sweat than from snow.
That’s why we’ve chosen to focus on water resistance + breathability. It’s safer, more comfortable, and more practical for the conditions where our gear shines.
Caring for Your DWR Finish
Like all water-repellent treatments, DWR works best with care. Over time, dirt and oils can reduce its performance. To keep your gear shedding water:
-
Wash periodically with a gentle, non-detergent soap.
-
Re-treat with DWR sprays or wash-in products when water stops beading up.
-
Avoid high-heat drying, which can damage fibers.
With care, your Wintergreen shell will maintain its protective qualities season after season.
FAQ: Water-Resistant vs. Waterproof
Q: Will this keep me dry in a downpour?
A: Our shells handle snow and light rain exceptionally well. For prolonged heavy rain, we recommend a fully waterproof shell, but remember, you’ll sacrifice breathability.
Q: Can I re-treat the DWR?
A: Yes. DWR can be reapplied using sprays or wash-in treatments. This helps restore water-shedding performance after extended use.
Q: How do I layer under a breathable shell?
A: Use a moisture-wicking base layer, an insulating midlayer like our fleece jackets, and top it with a shell anorak. This system balances warmth, breathability, and protection.
Q: Why not just make waterproof gear?
A: Waterproof shells don’t breathe well, which means sweat gets trapped inside. In winter, that can be dangerous. Our philosophy is to keep you dry from both sides.
Q: What is DWR?
A: Durable Water Repellent is a treatment that causes water to bead up and roll off fabric instead of soaking in. It can be maintained or reapplied as needed.
At Wintergreen, our philosophy is simple: gear should keep you warm, dry, and moving safely. That’s why we design for breathability first, with water resistance to shed snow and light rain. For most winter adventures, this balance beats “bone-dry” waterproof shells every time.
