If you are looking to buy the highest quality Japanese down jacket in the US, getting the sizing right is the most critical step. NANGA, established in 1941 in Maibara, Japan, is renowned for its premium "Aurora-Tex" sleeping bags and outerwear. However, for US customers, navigating the difference between Japanese sizing and American expectations can be tricky.

The fastest way to get the right fit is to ignore the letter size on the tag (S/M/L) initially and instead compare garment measurements using our TAKOUT NY NANGA Size Chart. At TAKOUT NY, we want to ensure you get the perfect fit the first time.

Why NANGA Sizing Feels "Different" in the US

NANGA Japan is a heritage brand deeply rooted in Japanese outdoor culture. Like many Japanese fashion brands, their sizing patterns are typically designed for a slightly slimmer frame compared to standard US "boxier" cuts. When searching for a NANGA down jacket or NANGA puffer, understanding this cultural difference in patterning is key.

When shopping for NANGA jackets in the US, you will often see items listed with their original Japanese (JP) size labels. A general rule of thumb used by fashion experts is that Japanese sizes often run one size smaller than their US counterparts. This is especially true for the torso length and shoulder width.

Quick JP-to-US Size Mapping (The "First Guess" Method)

While not a substitute for measuring, this mapping is a useful starting point for NANGA US sizing. We have expanded this chart to include approximate chest measurements to help you visualize the fit.

Important: This is just an estimate. Fit varies significantly by silhouette (e.g., the NANGA Aurora Down Jacket vs. the Mountain Lodge series). Always verify the specific measurements on the product page.

Step-by-Step: How to Measure for a NANGA Jacket

To avoid returns and ensure your NANGA down jacket fits perfectly for your needs, follow this simple process using a jacket you already own as a reference.

1. Measure Key Areas
Lay your reference jacket flat and measure the following in centimeters (as NANGA uses metric specs):

• Pit-to-Pit (Chest Width): Measure across the chest, just under the armpits. This is the most critical measurement for a NANGA puffer.
• Body Length: Measure from the high point of the shoulder down to the hem. Japanese jackets are often shorter in the body than American parkas.
• Sleeve Length: See note below regarding Raglan sleeves.

2. Compare to the Chart
Match your numbers to the product page. If you measure in inches, multiply by 2.54 to convert to centimeters.

3. Adjust for Layering

• City/Clean Fit: Choose measurements that match your current jacket exactly.
• Winter Layering: If you plan to wear a heavy fleece or hoodie, prioritize extra room in the chest (pit-to-pit).

Detailed Sizing by Model: Aurora, Hinoc, and Aerial

Different models have different "intended fits." Here are specific notes for our most popular items at TAKOUT NY based on customer feedback and sales data.

1. The NANGA Aurora Down Jacket (Flagship Model)

The NANGA Aurora Down Jacket is the brand's signature piece, featuring their proprietary waterproof-breathable Aurora-Tex® fabric.

Why is there no shoulder width?
You might notice that the size chart for the Aurora Tex Down Jacket does not list a shoulder width. This is because the Aurora model typically features Raglan Sleeves. Unlike standard set-in sleeves, Raglan sleeves extend fully to the collar, eliminating the shoulder seam. This design improves mobility for outdoor activities and reduces water entry points.

How to measure instead: Rely on the "Sleeve Length" measurement in the chart, which is taken from the center of the back neck to the cuff, rather than from the shoulder point.

Variant Note: For the NANGA Aurora Light Down Jacket, the fabric is thinner and lighter, often resulting in a slightly more "drapey" fit, but the sizing dimensions remain consistent with the standard Aurora.

2. The NANGA Aerial Down Parka Packable

The NANGA Aerial Down Parka Packable series is built for extreme portability. Because these are designed to be stuffed into packs for alpine use, they have a higher loft (puffiness) but a slightly shorter hem to accommodate climbing harnesses.

Fit Advice: If you are tall (over 6'0"), verify the torso length on the Aerial series carefully. You may need to size up to XXL solely for length, even if the L fits your chest.

3. The Hinoc (Takibi) Series

The Hinoc line uses fire-resistant fabric (Takibi fabric), which is a blend of Aramid fibers. This material is stiffer and less stretchy than nylon.

Fit Advice: Because the fabric has zero stretch, the Hinoc jackets can feel tighter across the back and shoulders than an Aurora jacket in the same size. If you have broad shoulders, definitely size up for the Hinoc line.

4. Mountain Lodge Down Jacket

This model is designed as a mid-layer or lightweight outer. It typically features a closer-to-body fit to maximize thermal efficiency.

Sizing Advice: If you have broad shoulders or prefer a relaxed look, consider sizing up one step from your "mapped" size.

Comparison: NANGA vs. Western Brands

To help visualize the fit, here is a comparison of how NANGA Japan sizing compares to common Western outdoor brands (like Patagonia or The North Face).

FAQ: Common Questions

Do NANGA jackets run small?
Compared to standard American outdoor brands, yes, NANGA sizing is generally trimmer. Most US customers find success sizing up one level (e.g., if you wear a US Medium, buy a NANGA Large).

Should I size up for the Aurora Down Jacket?
If you are between sizes or plan to layer heavily for winter camping, sizing up is recommended. However, for a sleek city look with just a t-shirt underneath, your mapped size may work.

Is the down quality the same across all jackets?
Generally, yes. NANGA uses premium Spanish Duck Down (typically 760FP to 860FP), cleaned in Japan to exacting standards. This high fill power means the jacket provides immense warmth without needing to be bulky, which influences the slimmer silhouette.

Are there size differences between model years?
Yes. NANGA occasionally updates its patterns. We keep our specific product charts updated to reflect the exact inventory we carry at TAKOUT NY.

How does NANGA's sleeping bag sizing translate to their apparel?
While NANGA sleeping bag sizing focuses on total height (Regular vs. Long), their apparel line requires standard 3D fit measurements (chest/shoulder). Do not rely on your sleeping bag size code when ordering jackets; check the specific garment measurements above.
