When it comes to outerwear, warmth isn’t only about insulation—it’s about how your jacket fits. A well-fitted parka seals in more heat, moves with your body, and layers easily, keeping you comfortable through season after season of changing weather.
That balance between form and function is what defines Quartz Co., a Canadian brand designing refined, responsibly made outerwear that thrives in the world’s harshest winters. Each jacket is engineered for performance, durability, and timeless appeal—proof that technical design can look as good as it feels.
Still, finding your perfect size online isn’t always easy. Most shoppers agree that “sizing uncertainty” is one of the biggest barriers to buying premium outerwear. That’s why we created this Quartz Co. fit guide—to help you measure accurately, understand each fit, and shop confidently. Whether you’re commuting downtown or venturing north of 60°, the right fit makes all the difference.
Understanding Quartz Co. Fits
Founded and designed in Canada, Quartz Co. combines technical performance with clean urban tailoring. Every jacket is cut and stitched to maintain the perfect balance of mobility, structure, and warmth retention—qualities that depend heavily on choosing the right fit.
Quartz Co. offers these primary silhouettes: Fitted, Semi-fitted, Slim-straight, Regular, and Oversized. Each one’s designed with a specific purpose in mind. In other words, the right fit isn’t just about how the jacket looks; it also affects its ability to insulate, its layering potential, and your freedom of movement.
Fitted & Semi-fitted — Tailored Warmth
Fitted (or slim) jackets follow your body’s natural lines without ever feeling restrictive. Designed with a close silhouette and minimal bulk, the Quartz Co. Fitted style is ideal for city living, cycling commutes, and modern wardrobes where function meets refinement.
Because the fabric sits nearer to your body, warm air stays contained, and insulation performs at peak efficiency. The result is a sleek, wind-cutting layer that moves fluidly while maintaining consistent warmth. While the silhouette flatters most body types, it shines in temperate or urban climates where lighter layering is the norm.
Semi-fitted also follows your body’s natural lines, but with a little more wiggle room to allow for light and heavier layers.
Fitted and Semi-fitted styles are best for: commuters, style-focused wearers, temperate climates, or those who rarely wear heavy mid-layers.

Slim-straight & Regular — Everyday Balance
Slim-straight styles are another step up from their slim fits. The only difference is that it doesn’t cinch at the waist, allowing for more freedom of movement, while still providing some contouring for a refined look.
Regular fit is the most versatile of Quartz Co.’s fits, delivering all-day comfort with enough space for a warm midlayer while maintaining an urbane, structured look. It’s the silhouette most people gravitate toward instinctively—neither snug nor oversized, but perfectly balanced.
Quartz Co. slim-straight and regular-fit coats are engineered to provide a more natural range of motion through the shoulders, arms, and waist, for a comfortable commute to work, catching a flight, or exploring in unpredictable weather. The moderate room also helps evenly distribute insulation, ensuring consistent warmth without adding weight or bulk.
Slim-straight and regular styles are best for: all-season versatility, moderate layering, and balanced silhouettes.

Oversized Fit — Freedom to Layer
Oversized prioritizes comfort and adaptability above all else. Roomier through the torso, shoulders, and sleeves, the Quartz Co. oversized fit is designed for seamless layering—perfect when temperatures plummet and insulation becomes your first line of defence.
The extra volume accommodates thick sweaters, fleece pullovers, or down vests without feeling bulky or stiff. That additional space also improves airflow and maintains insulation loft, preventing the down or synthetic fill from being compressed. The result is a parka that stays warm, breathable, and mobile, even in deep cold.
Beyond pure performance, oversized pieces embody the easy confidence of Canadian winter living: throwing on your coat for a morning walk, chopping wood at a cabin, or braving a whiteout on your daily commute. These jackets keep you warm without restriction—protective yet unpretentious.
Oversized styles are best for: colder regions, heavy layering, and those who love an easy, roomy feel.

How to Measure Yourself for a Quartz Co. Jacket
Getting the right fit starts with knowing your numbers. Even the most advanced outerwear performs best when it moves naturally with you—and that precision begins with a quick measuring session. Taking a few minutes now will save you time (and return shipping) later when referencing the Quartz Co. size guide.
All you’ll need is a soft measuring tape, a mirror or a friend’s help, and light base-layer clothing—no bulky sweaters or jackets.
The chart below outlines how to measure key areas of the body for the best fit. Each measurement directly reflects how your Quartz Co. jacket performs in terms of warmth and movement. Use it alongside the Quartz Co. jacket size chart when shopping online.
Step-by-Step Measuring Guide
Step 1: Determine your size
Begin by measuring your shoulder width (1), sleeve length (2), bust (3), waist (4), and hips (5).
Pro tip: Take each measurement twice for consistency. Even a one-centimetre difference can affect your fit choice!
Common Mistakes to Avoid
- Measuring over heavy clothing
- Pulling the tape too tight
- Guessing instead of checking each side (especially shoulder width)
Step 2: Converting your size from your measurements
Once you’ve recorded your measurements, it’s time to turn numbers into confidence. Compare them to the official Quartz Co. size chart and use the guide below to fine-tune your choice. These Quartz Co sizing tips will help you decide whether to size up, down, or stay true.
If you typically wear European or US sizes, note that Quartz Co. uses North American sizing (USA in the chart), closely aligned with standard Canadian measurements.
Note:
- Slim Fit/Fitted → Size Up if you fall between two sizes or plan to wear a sweater or light fleece underneath.
- Semi-Fitted to Regular → True to Size for most people—provides ample room for light layering without excess bulk.
- Oversized→ Size Down if you prefer a more streamlined silhouette.
Once you’ve ordered and received your jacket, it’s time for the final fit check—the movement test. Raise your arms, cross them over your chest, and twist slightly at the waist. If you feel pulling at the shoulders, armpits, or elbows, the size is too small; if you feel bunching at the back, there’s a good chance it’s a tad too roomy.
The bottom line is this: Proper sizing not only improves comfort but also prolongs your jacket’s life. That’s because a correctly fitted coat distributes tension evenly across seams and zippers, reducing wear over time.
Consider your jacket’s uses as well: For Atlantic or Prairie winters where windchill dominates, maybe a Regular or Oversized fit will better accommodate the cold by allowing you to wear thermal layers. In milder coastal or urban settings, Slim fits deliver the best balance of mobility and heat retention.
Quartz Co. Sizing by Body Type and Lifestyle
Even after all those measurements, finding your perfect Quartz Co. jacket isn’t just about numbers—it’s about how you wear it. Whether you layer heavy, move fast, or live somewhere in between, these profiles make it easy to choose the right fit at a glance. Use the table below as a quick reference.
Profile | Recommended Fit | Why It Works |
The Layering Lover | Oversized | Extra volume for down or fleece mid-layers |
The Minimalist Commuter | Fitted/Semi-fitted | Streamlined under backpacks or office attire |
The Weekend Explorer | Slim-straight/Regular | Flexible for hikes, errands, and travel |
Taller / Broader Frames | Regular → Oversized | Added shoulder and sleeve space |
Cold-Climate Residents | Oversized | Prevents insulation compression in deep winter freezes |
Transitional-Season Wearers | Fitted → Regular | Light layering for spring and fall |
By Climate
- Arctic or Prairie cold: Consider relaxed for layering down or wool.
- Urban coastal winters: Fitted or Regular for mobility and wind protection.
- Temperate zones: Regular for year-round adaptability.
Ultimately, the choice is yours, and Quartz Co.’s range of jackets provides styles for just about any lifestyle.
FAQ
Do Quartz Co. jackets run true to size?
Yes. All of their different fits, from Fitted to Oversized, are calibrated to deliver the intended silhouette. Most customers find their usual size works well, but we always recommend checking the Quartz Co. size chart for the most precise match to your body measurements.
What if I’m between sizes?
Consider your climate and layering habits. For heavy knits or colder regions, size up to preserve mobility and insulation loft. For a sharper outline in milder weather, size down slightly—but only if you don’t plan to wear thicker layers underneath.
Can I size down oversized styles?
Definitely, sizing down slightly can create a neater silhouette while maintaining full warmth. Just ensure the shoulders and sleeves still allow a natural range of motion, especially if you’ll be driving, hiking, or commuting daily.
What’s the best fit for travel?
We recommend a Regular fit for travel. It provides enough room for a light mid-layer yet remains compact enough to pack or wear comfortably through airports and variable climates. Many travellers find it’s the most versatile balance of performance and polish.
Is it easy to exchange sizes?
Yes. Altitude Sports offers a simple 30-day return policy, so you can order confidently, try your jacket on at home, and swap if needed. Our customer service team can also advise on measurements before you buy, helping ensure the perfect fit on the first try.
How do men’s and women’s fits differ?
Women’s jackets are slightly narrower at the waist and shorter in sleeve length, while men’s designs allow for broader shoulders and longer arms. Otherwise, both collections follow identical sizing logic—so a Medium in one will align closely with a Medium in the other.
Find Your Fit, Own the Cold
Choosing the right Quartz Co. fit is more than a sizing decision—it’s a comfort strategy for years to come. A jacket that matches your build and habits keeps you warmer, moves better, and endures longer. Plus, it looks awesome.
With decades of Canadian design expertise, Quartz Co. continues to refine how winterwear should feel: protective yet elegant, technical yet timeless. Whether you opt for a streamlined city coat or a parka built for the polar vortex, each piece is crafted to move naturally with you.
