Innovative Collaboration Between LOWERCASE and Knot THE STRAP Launches New Stylish Apple Watch Bands

A Unique Collaboration for Apple Watch Bands

In the world of fashion and accessories, collaborations often yield some of the most innovative and exciting designs. This is precisely the case with the new partnership between LOWERCASE, led by the renowned creative director Yukihiro Kajiwara, and Knot THE STRAP, a brand specializing in custom watch straps under the umbrella of Maker's Watch Knot. Their latest creation targets Apple Watch users with a cutting-edge functional fashion strap that merges practicality with style.

Emphasis on Functional Materials

The collaboration features a variety of materials aimed at enhancing both the look and functionality of the straps. Key offerings include:

- One leather strap available in three colors
- Two fabric straps, each designed with distinct functional attributes.

NATO Design and Waterproof Leather

Responding to requests for stylish NATO-style Apple Watch straps, LOWERCASE's Kajiwara was determined to create an attractive design. The primary material is waterproof leather, which has garnered popularity for its high-performance qualities.

The leather incorporates Scotchgard technology developed by 3M during the tanning process, instead of simply coating the surface. This treatment ensures the straps maintain the plush feel of smooth leather while providing authentic waterproof capabilities, making them as functional as they are fashionable.

A Blend of Military and Urban Style

The straps feature a military-inspired design made with meticulous craftsmanship. The layers consist of double-sided stitching with backing, offering an appealing combination of military toughness and an urban aesthetic.

A convenient touch allows the strap length on the 6 o'clock side to be 150mm, aligning with the traditional NATO design that includes a tapered end that can be folded back into the ring.

Fabrics Offering Cutting-Edge Features

Two types of fabric straps have also been introduced in this collaboration:
1. Three-layer Waterproof, Moisture-permeable 3D Layer Material:
This innovative material boasts a unique polyurethane microporous membrane structure for superior waterproofing and breathability, thus preventing moisture buildup during wear.
2. COOLMAX and Heat Shield Fabric:
The inner layer utilizes COOLMAX technology for effective moisture absorption and evaporation, ensuring comfort. With heat-shielding capabilities incorporated into the outer fabric's fibers, this strap aims to balance heat resistance and moisture-wicking features elegantly.

Both fabric strap types reflect a commitment to quality, combining waterproof leather details at the easy lever and loop areas, making them washable and user-friendly.
