HI-FLYER" and "LIST" are released from the "Full tannin pit-tanned shrink horsehide" series!

STRUM" 2025 SPRING / SUMMER "MASSIVE" releases one after another!
From the "Full tannin pit-tanned shrink horsehide" series, which has been the face of STRUM since its first release in 2020-21 A/W, the standard double riders models "HI-FLYER" and "LIST " are now available!
This time, we will introduce them in three parts: leather features, model features, and coordination!
(1) Characteristics of leather : We dare to use only horsehide leather with many scratches in particular, and by shrinking it, the natural grainy texture is accentuated.
- We dare to use only horsehide with especially many scratches to make the best use of its characteristics.
- Pit-tanning : Tanned with tanning agents. Pit-tanning: A tanning process in which tannin is added to the leather over a long period of time using a huge bath-like pit.
- By soaking the leather in tannin for a long time, the natural texture of the leather is preserved and the leather becomes strong and durable.
- Shrink tanning Shrink: After pit-tanning, the leather is dyed and further heat-tanned, shrinking it to half its normal size (from about 2m to 1m), which accentuates its natural graininess.
The above process fuses thescratches of horsehidewith the grain of the shrink tocreate a rugged and masculine look. The initial texture is dry and bouncy, but the more it is worn, the more it becomes more shiny.
If Burning dyed is a leather that grows in color, shrink horsehide is a leather that grows in the shape of your body.

The feature of the model: STRUM's standard double riders "LIST" and "HI-FLYER".
LIST
Based on the Ronjan type, this model emphasizes an adult atmosphere by concealing the zippers on the chest and hip pockets. The shoulder slopes and back climb are kept to a minimum, and fine adjustments have been made in various areas to create a pattern that emphasizes ease of wear.
HI-FLYER
The HI-FLYER incorporates vintage-inspired details and is characterized by its irregular pocket layout. It is a model with gimmicky features such as a windproof collar.
Coordinates (LIST): This all-black coordinate is accented with a sleeveless hoodie, which is unique to this time of the year, and is worn with individualistic, roomy denim, and engineer boots for a masculine look.
The heavy feel of the leather is combined with a "loose" look to create both a sense of the season and a sense of individuality. The key to this styling is the sleeveless hoodie, which is unique to this time of year.
At first glance, the all-black coordinate is simple, but the sleeveless hoodie in the inner layer softens the strength of the leather while adding an edgy impression. The airy feel around the arms gives an excellent sense of balance to a black style that tends to be heavy.
The bottom is a pair of denim with a generous fit, creating a rugged yet rough airy look. The moderate volume of the top accentuates the contrast with the top and creates a rhythm to the overall look.
The tough appearance of the engineer boots on the feet, which are firmly tightened, brings the entire style together in a masculine manner.
It is neither "wearing too much" nor "taking too much off". The STRUM all-black style for spring, which appeals with the right amount of material and volume, is a must-have reference.

④ Coordinates (HI-FLYER): A cool, dry-touch shirt paired with classy drum-dyed wide pants accentuates the rugged look of shrink-wrapped hose in this spring coordinate.
With the arrival of spring, we want to incorporate "airiness" into our outfits as well. This coordination is a layered style typical of STRUM, with a perfect balance of coolness and ruggedness.
The star of the show is the shrink-wrapped horsehide rider's jacket at the top of the layer. The tough texture of the leather and the expression of the grain add depth and power to the light style.
The rugged yet not too assertive, it tightens the coordination without losing the sophisticated impression, and the nuanced color of the shirt with a slight beige tinge in the layers gives an elegant and clean impression, while adding gentle shades to the monotone coordinates.
For bottoms, we selected wide pants that have been drum-dyed to give them a deep look. The silhouette, while wide, is not excessive, and has a sense of modesty and calmness.
Enjoy STRUM's unique spring look with the one-of-a-kind balance of sophisticated materials and rugged leather.
