In this article, we take a deep dive into the two key pants models from the Japanese men's brand "IRENISA" for the 2025 Spring/Summer (25SS) collection: the "Two Tucks Wide Trousers" and the newly introduced "Two Tucks Wide Cargo Pants".
Since its official launch with the 2020-21 Fall/Winter collection, IRENISA has been a brand to watch, known for its refined pattern-making skills and Japan’s high-level sewing craftsmanship, establishing a unique world of its own.
This season’s theme, "Variable Void", evolves the concept of consciously shaping the "Ma" (the space between the body and clothing), and even the staple pants have received new interpretations.
In this feature, we individually review the Two Tucks Wide Trousers and the Two Tucks Wide Cargo Pants.
We will thoroughly explain their designs, fit, material differences, styling versatility, and care instructions for long-term use, all from the perspective of a specialty retailer.
With physical stores in Osaka and Kyoto continuously carrying IRENISA, we also bring you firsthand feedback from the sales floor and staff wear reports. Be sure to read to the end!
Two Tucks Wide Trousers: The Refined Space Created by IRENISA’s Signature Pants
Design and Silhouette: A Fusion of Classic and Modern
The "Two Tucks Wide Trousers" feature two tucks at the front, creating a wide silhouette with generous room around the waist. By blending the classic element of two tucks with a modern sense of relaxation, they achieve a refined wide look without being overly loose.
There are no special drawcords or adjustment features at the hem; the focus is entirely on "the beauty of the drape". Some models also feature center creases, adding a sharp and polished impression. They are highly versatile, easily adapting to a wide range of styles from formal to casual.
Material: Bishu Wool/Mohair Blend Tuxedo Cloth
When it comes to IRENISA’s signature fabrics, wool/mohair blend from Bishu stands out. The fabric, woven in a tuxedo cloth style using ultra-high-twist merino wool yarns combined with mohair, offers both a dry touch and a supple drape.
Another key feature is the unique texture created by vintage-like vertical striations. The durability characteristic of high-twist yarns also ensures that the pants retain their shape even with daily wear.
Functionality and Comfort: Versatility Provided by the Elastic Waistband
Despite its classic appearance, many models feature elastic inserts at the sides or back of the waistband, ensuring a comfortable fit even without a belt. Whether you wear them lower at the hips or properly at the waist, you can adjust the impression depending on how you wear them.
The roomy fit around the hips and thighs gently tapers toward the hem, allowing the pants to maintain a clean silhouette while taking advantage of the volume. This balance of relaxation and elegance has earned high praise among fashion enthusiasts.
Staff Wear Report
・Staff (170cm / standard build): Wearing size 2. Thanks to the elastic waistband, both hip-hugging and waist-fitted styles are possible. Pairing with slightly cropped hems works well with either dress shoes or sneakers.
Versatile Styling: From Business to Dressy Looks
The Two Tucks Wide Trousers can be styled almost like formal attire when paired with a jacket. Choosing colors like black or navy enhances their formality, making them potentially suitable even for formal events such as weddings or funerals.
On the other hand, pairing them with a simple cut-and-sew or sweatshirt allows them to function as mode-inspired casual wear. According to feedback from stockists, they are often praised as “versatile pants that match any top.”

Two Tucks Wide Cargo Pants: 25SS New Release Fusing Classic Design with Cargo Elements
Design and Silhouette: The Perfect Balance of Elegance and Military Influence
The "Two Tucks Wide Cargo Pants" newly introduced in IRENISA 25SS are crafted by incorporating cargo pant details into traditional wide slacks, resulting in a piece that balances both functionality and design.
The cargo pockets are positioned slightly lower, and the overall shape maintains a wide straight silhouette. True to IRENISA’s brand concept of "CHIC WITH SARCASM", the fusion of dress elements and military details creates a unique, distinctive aesthetic.

This piece uses nylon taffeta woven at high density with varying thicknesses of warp and weft threads. It features powerful water-repellent processing, providing reliable protection against sudden rain.
Compared to typical functional fabrics, it has more thickness and firmness while offering a smooth, soft touch. The mode-inspired sheen is moderately subdued, giving it an elegant look that blends seamlessly even in urban settings.
Details: Drawcord Hem & Cargo Pockets
The hem features a drawcord made from the same fabric, allowing you to adjust the silhouette. You can enjoy wearing them as wide straight pants or cinch the hem for a tapered look.
Some versions also include an adjustable waistband with elastic and buckle tabs, skillfully blending workwear and military functionality without compromising the elegant balance characteristic of IRENISA.
Comfortable Fit: Suitable for Active Scenes
The lightness of the nylon fabric and the moderate roominess ensure great mobility, making these pants perfect not only for city walks but also for active settings such as outdoor festivals and travel.
While following the elegant construction of the "Two Tucks Wide Trousers," these pants add ample cargo pocket storage and water repellency, making them a highly practical option.
Staff Wear Report

The Example of Coordination
Here we introduce styling examples featuring both pants models.
Take inspiration from the various coordination examples using these highly versatile pants.
A Modern Wide Style Perfect for Both On and Off-Duty Wear
While the inner and bottoms create a polished combination, the styling is given a casual twist by pairing them with a denim jacket.
This time, a white shirt is added for a dressier look, with the denim jacket providing a touch of casualness.
These pants truly shine whether you lean toward a more mode style with polished shoes or boots, or go for a relaxed feel with sneakers.
A Modern Silhouette Created by Combining Heavy Wool and a Lightweight Shirt
Layering a long-length shirt under a wool jacket creates a styling that feels rich in depth without becoming too rigid.
The subtle length of the shirt peeking out from under the jacket softens the formal impression while adding just the right amount of volume to the upper body.
As bottoms that can flexibly adapt to both on- and off-duty settings, this piece greatly expands your coordination possibilities.
A Wide Silhouette with a Relaxed Feel to Enjoy the Depth of Dark Tones
This look combines a black denim jacket layered over a matching black long-sleeve T-shirt, paired with navy wide cargo pants.
Instead of keeping the top and bottom in the same tone, the bottoms are intentionally given a slightly different hue to avoid monotony and create a subtle contrast.
While maintaining a calm, subdued color palette, the difference in shades and textures between the top and pants adds definition, resulting in a modern, relaxed urban style.
A Wide Silhouette and Jacket Combination That Exudes Mature Sophistication
This styling brings together items from the same brand, with the addition of cargo details creating just the right sense of relaxed ease.
While the classic foundation is built with a black tailored jacket and a white short-sleeve shirt, the pants feature a wide silhouette with cargo pockets for a fresh twist.
The dressy upper half and the casual elements in the bottoms together achieve a refined balance that is distinctly characteristic of the brand.
Trousers and Cargo, summary of each feature
So far, we have looked at the two models individually, but both are based on a "Two Tucks" design that provides room around the waist and a wide silhouette. With that in mind, here are the key differences:
- Two Tucks Wide Trousers:
・Made from a wool/mohair blend, offering a refined silhouette with elegant drape.
・No drawcord; constructed to perfect the classic wide slacks.
・Ideal for formal or polished styles. - Two Tucks Wide Cargo Pants:
・Crafted from water-repellent nylon taffeta, more casual and suited for active use.
・Features drawcords at the hem and cargo pockets, allowing for versatile silhouette adjustments.
・Incorporates military elements, making them easy to use across various settings.
If you prioritize a formal feel and luxurious material, choose the Trousers. If you need something more active and functional, the Cargo Pants are the way to go. Of course, owning both will allow you to fully experience the world of IRENISA across different seasons and occasions.
Size Selection and Maintenance: Common Points for Both Models
Basic Sizing: Versatility Created by Elastic Waistbands and Tucks
Both models often feature partial elastic at the waist, allowing for multiple ways to wear a single size. One major advantage is the ability to adjust the fit according to body changes or balance with different tops.
While referring to the official size specs (waist, rise, thigh width, hem width, etc.), we highly recommend trying them on in-store if possible to experience the fit firsthand.
Care Instructions and Points to Note
Wool/Mohair:
・Dry cleaning recommended. While resistant to wrinkling, use a pressing cloth if ironing.
・Be mindful of pilling in areas prone to friction. Regular brushing helps maintain the fabric.
Nylon Taffeta:
・Dry cleaning recommended, hand-washing is possible.
・To maintain water repellency, avoid fabric softeners and high-heat drying. Low-temperature ironing is recommended.
Because these fabrics are selected for their longevity, regular maintenance and proper storage are key to keeping them in top condition.
