[Review] Momotaro Jeans 3105SP Type III Selvedge Denim Jacket: The Journey of Breaking in My Own Armor

  

Hello, this is Lislab.

In the world of denim enthusiasts, there is a brand often hailed as the "Pride of Okayama"—Momotaro Jeans.

Following its steadfast philosophy, Momotaro is renowned for its deep indigo dyeing and use of Zimbabwe cotton, achieving a perfect balance between comfort and durability. This deep indigo creates a sharp, high-contrast fade against the white cotton core as it ages, resulting in a one-of-a-kind wash unique to the wearer.

While there are many heritage brands focusing on Levi's reproductions, those who want to experience the extremes of fabric and dyeing—infused with a unique identity and philosophy—eventually find their way to Momotaro.

Today, I’m introducing the 3105SP Type III Denim Jacket, which has a fandom as strong as their denim pants. Let’s dive into the unique charm of denim uppers and the "painful" yet rewarding journey of breaking them in.

01. Product Details

"The Pinnacle of Japanese High-End Denim and the Sophisticated Type III Silhouette"

• Model: Momotaro Jeans 3105SP Type III Selvedge Denim Jacket

• Status: Owned for 3 years / Worn less than 20 times / Unwashed

• Features: Heavyweight fabric repeatedly dyed to achieve the deepest indigo shade in the world
• 15.7oz Sanforized & One-Wash - Pre-shrunk through anti-shrinkage processing and pre-washing to ensure a stable fit.
• Sturdy yet soft texture achieved by using the legendary Zimbabwe cotton, known for its exceptional softness.
• Vintage silver buttons engraved with the peach and brand name, "Going to Battle" signature painting on the left arm, Pink (Momo) selvedge, Deerskin leather patch, and the Type III jacket design.



When I first encountered this jacket, the only word that came to mind was "Armor." The 15.7oz weight feels substantial, and the "Tokunou" (extra dark) indigo is so deep it can almost be mistaken for black.

Inside, however, you'll find Momotaro's signature humor—the pink selvedge line and the deerskin patch.

The iconic white stripes on the left arm act as a perfect visual accent to the otherwise rugged and dark denim.



Denim jackets have evolved through Type I, II, and III. While Types I and II offer a boxy, cropped, classic vintage look, the Type III features a slightly tapered waist and a longer body, making it ideal for modern styling. The two chest pockets and the "V" seams are the hallmark features of this silhouette.



Currently, it is almost impossible to find this original model in South Korea. Due to the brand's recent rebranding, this specific version—especially in the "Golden Size" 40—is a rare gem even in Japan. Fortunately, my brother brought this as a wedding gift from his trip to Tokyo, and I’m honored to add it to my archive.

02. Sizing

"A Brother's Eye for Style"



Size 40 Measurements:

• Chest: 53cm

• Length: 70cm

• Shoulder: 47cm

• Sleeve: 62cm

Detailed sizing data for this product is scarce globally, so I measured it myself to provide a guide.





I usually wear a size Large. I chose Size 40 to allow for layering with hoodies or cardigans.

Since the Type III has very structured shoulders, sizing up is the secret to maintaining a clean silhouette while layering.

My brother, who is taller and larger than me, personally tried it on at the Tokyo store to ensure it would be the perfect fit for my frame.

03. Aging Data & Fit

"The Patience Required to Overcome Discomfort"



Even with the legendary softness of Zimbabwe cotton, a denim jacket feels much stiffer and more uncomfortable than denim pants. This is because the upper body requires more frequent and delicate movements than the legs. Furthermore, the range of motion is narrower, making the honeycomb (arm crease) fading process significantly slower.





I’ve owned it for 3 years and worn it about 20 times, but it still feels "brand new." However, seeing the creases slowly setting in around the elbows gives me hope for the high-contrast white fades to come.

This stiffness is what holds the creases in place; the more you endure it, the sharper the fades will be.



Closing: If You Want to Create Your Own Jacket

A denim jacket is more than just fashion or protection against the cold; it’s an archive that records the seasons and the owner’s persistence. I enjoy the tension of a new garment, but I’m even more excited for how the indigo will mature and settle into my body shape years from now.

If you’re tired of fleeting trends, I highly recommend a high-quality denim jacket. It offers a sense of "growth" alongside the wearer that no luxury brand can replicate. I’ll continue to record and share how this piece evolves through my daily life.

Thank you for reading this long journey.
