NEEDLES' "HD PANTS" are a series of pants with a unique silhouette that draws you in every time you wear them. ARZACH carries several models of these pants, and they are one of the items we receive the most inquiries about, regardless of the season.
"What's the difference between FATIGUE and MILITARY?" "Should I choose 12oz or 6oz denim?" "How's the sizing?" — This article compares and explains all eight styles currently available from ARZACH. It's designed to be helpful for both first-time buyers and those who already own a pair and are looking for their next pair.
— What is HD (Hizadel)?
"HD" is an abbreviation for "Hiza-Deru," which refers to a silhouette where the knees appear to protrude forward when wearing pants.
Normally, the appearance of bulging knees on pants is a sign of wear and tear from years of use—a negative image. However, Keizo Shimizu, the designer of NEEDLES, intentionally incorporated this negative phenomenon as a design element for his pants. The darts at the waist and hem create a three-dimensional silhouette that bulges significantly in the front. When viewed from the side, the forward protrusion of the knees is clearly visible.
It's a sign that you're getting tired.
NEEDLES turned it into a silhouette.
The waist is adjustable with a drawstring, offering flexibility to wear even if the waist size doesn't quite fit. The relaxed silhouette and unique volume create a comfortable fit that you won't want to take off once you've tried them on.

Left: HD PANT FATIGUE OLIVE (¥26,400) / Right: HD PANT FATIGUE BLACK (¥26,400)
HD PANT — FATIGUE
100% Cotton / Sizes XS, S, M / ¥26,400 (tax included) / Made in Japan
The most basic and popular style in the Hizadel Pants series. It incorporates details from fatigue pants (workwear/work clothes designed to reduce fatigue), featuring L-shaped patch pockets on the front and side adjusters. Made from cotton back satin, it offers moderate firmness and durability, and its texture changes with wear. Available in two colors: Olive and Black. Olive is the most natural color in the context of workwear and military wear. Black offers the greatest versatility in styling and is often chosen as a first pair.

Left: HD PANT MILITARY KHAKI (¥26,400) / Right: HD PANT MILITARY BLACK (¥26,400)
HD PANT — MILITARY
100% Cotton / Sizes XS, S, M / ¥26,400 (tax included) / Made in Japan
This model features a simpler silhouette than the FATIGUE, and adheres to more authentic military pant details. The front pocket shape differs from the FATIGUE, giving it a cleaner look. Pockets are also placed on the back. The material also differs slightly from the FATIGUE, with a more matte and simple texture. KHAKI is a classic color for military and work pants. BLACK has a more minimalist impression compared to the black of the FATIGUE. If you're having trouble deciding between the two styles, it's recommended to choose based on your preferred style of dressing.
KHAKI → Product Page BLACK → Product PageFATIGUE vs MILITARY — A Summary of the Differences
FATIGUE : L-shaped patch pockets, side adjusters, cotton back satin material. A style with prominent pocket details that gives it a more "workwear" feel.
MILITARY : Simple pockets, back pockets, weather-resistant material. A cleaner, simpler "military pants" look.
Both are the same price (¥26,400). If you want to focus on the details, FATIGUE is recommended, but if you want something simple to wear, MILITARY is a good choice.
— III. HD PANT BDU — BLACK
HD PANT BDU BLACK (¥26,400)
HD PANT — BDU
100% Cotton / Sizes XS, S, M / ¥26,400 (tax included) / Made in Japan
BDU stands for "Battle Dress Uniform." Its most distinctive feature is the large cargo pockets located on the sides of the knees, making it the most striking and three-dimensional model of the three. The material is slightly glossy, soft, and lightweight. Furthermore, it has a drawstring at the hem, which, when tightened, creates an extremely balloon silhouette. This "adjustable hem" is a feature unique to the BDU model. It has a stronger personality than the FATIGUE or MILITARY models, making it perfect for those who want to enjoy a more NEEDLES-style look.

Left: HD JEAN 12OZ INDIGO (¥31,900) / Right: HD JEAN 12OZ BLACK (¥31,900)
HD Jeans — 12oz Denim
100% Cotton (12oz denim) / Sizes XS, S, M / ¥31,900 (tax included) / Made in Japan
This model features a knee-length silhouette expressed in denim material. The 12-ounce denim has a weight and thickness close to that of authentic jeans, and you can enjoy the aging process as it fades and develops a unique look with wear. INDIGO is a classic indigo blue, while BLACK is a sharp black denim. The price is higher (¥31,900) compared to the three cotton-based models (FATIGUE, MILITARY, and BDU) due to the use of denim material. If you are looking for the weight and aging process characteristic of denim, this is the model for you.
12oz INDIGO → Product Page 12oz BLACK → Product Page— VHD JEAN 6OZ DENIM — INDIGO
HD JEAN 6OZ DENIM INDIGO (¥20,900)
HD Jeans — 6oz Denim
100% Cotton (6oz denim) / Sizes XS, S, M / ¥20,900 (tax included) / Made in Japan
This is the lightest denim model among the 8 styles, and also the most reasonably priced (¥20,900). The thin 6-ounce denim is lighter and cooler than 12oz denim, making it comfortable to wear in spring and summer. It's recommended for those who want to try out a denim knee-length silhouette, or those who want to start with an easily accessible price range. Because the material is thinner, it features a light and refreshing feel rather than the strong aging process of 12oz denim.
6oz INDIGO → Product PageJEAN 12oz vs 6oz — Summary of Differences
12oz (¥31,900) : Similar weight and thickness to jeans. Enjoy the aging process as you wear it, with fading and wear marks developing over time. Suitable for all seasons.
6oz (¥20,900) : Lightweight and thin, suitable for spring and summer. The most affordable in the series. Ideal for those who prioritize lightness over aging and wear.
If you're looking for the joy of "breaking in" denim, choose 12oz; if you prioritize lightness and price, choose 6oz.
— Size guide (applies to all models)
This section explains the sizing for all models of Hizadel pants. All models are available in three sizes: XS, S, and M, and the waist can be adjusted with a drawstring.
Points to consider when choosing a size
When choosing the size of Hizadel pants, it's best to base your decision on the "length." The waist can be adjusted with a drawstring, so even if the waist is a little large, you can still wear them, but the length cannot be adjusted.
Guideline: XS → Height 165-170cm / S → Height 170-177cm / M → Height 177-183cm or taller
For women, XS to S size is a good guideline. Many people choose S if they want an oversized fit.
| SIZE | waist | Total length | Hem width | Approximate height |
|---|---|---|---|---|
| XS | 76cm | 96cm | 26cm | Around 165-170cm |
| S | 80cm | 98cm | 27cm | Around 170-177cm |
| M | 84cm | 100cm | 28cm | 177cm and above |
*The above measurements are for reference only for the FATIGUE model. There may be slight differences depending on the model. The waist is adjustable with a drawstring. Please allow for some individual variations.
— Outfit suggestions
White T-shirt + Hiza-del pants (the simplest and most correct choice)
This is the outfit that best highlights the silhouette of the Hizadel pants. The top is simply a white T-shirt. Whether it's a cotton (FATIGUE, MILITARY, BDU) or denim, the white T-shirt keeps the volume of the pants to the forefront. Sneakers, sandals, or leather shoes all work well with this outfit.
Knit sweatshirt + wide-leg pants (Autumn/Winter outfit)
When pairing it with voluminous knits or sweatshirts, deliberately slimming down the volume of the upper body creates an A-line silhouette. Wearing a plain cotton turtleneck from DRESS as an inner layer and layering a cardigan over it is a classic ARZACH look.
Shirt (untucked) + Hiza-del pants (casual clean)
This outfit features high-quality shirts, such as INTÉRIM's silk noil shirt or OUTIL's tricot, worn untucked and paired with wide-leg pants. The laid-back feel of the shirt and the wide silhouette of the pants create just the right amount of relaxed style.
Women's styling — XS size for the perfect length
For women, we recommend the XS size. The waist area is roomy, so please adjust it with the drawstring. If the length is right, the silhouette will look beautiful. Pairing them with a compact top or cropped knit will highlight the volume of the knee-length pants, creating a well-balanced style.
