Strike Core

Carbon Fiber Wallet

Traditional format. Aerospace materials.

Most wallets are designed to look slim on day one. Strike Core is designed to stay slim on year five.

Standard leather wallets stretch under card load. The Carbitex CX6 / Omniflex carbon fiber panel in Strike Core resists deformation permanently — the same 7mm profile on day one as on year five. Paired with K-Leather (kangaroo leather, ethically sourced Australia), the exterior remains supple without stretching or cracking under daily use.

At 62 grams and 7mm closed, Strike Core carries less than most minimalist wallets — while fitting more. No external clips, no elastic bands, no moving parts. Structural integrity from the material itself.

Full-size EUR and USD bills. Back pocket or jacket carry. Classic bifold architecture — rebuilt from aerospace materials.

Why Strike Core Is Different

Most wallets are designed to look slim on day one. Strike Core is designed to stay slim on year five.

Permanent structure retention

Standard leather wallets stretch under card load and increase in thickness within months. Strike Core uses a rigid carbon fiber layer that resists deformation permanently. The same 6mm profile on day one as on year five.

Traditional carry, re-engineered

Full-size EUR and USD bills. Back pocket or jacket carry. Classic bifold architecture. Rebuilt from aerospace materials. For those who carry with intention and refuse to compromise.

Zero bulk. Zero compromise.

At 55 grams and 6mm closed, Strike Core carries less than most minimalist wallets, while fitting more. No external clips, no elastic bands, no moving parts. Structural integrity from the material itself.

Built for decades, not seasons

ColdFire wallets are not fashion accessories. They are engineered carry tools, designed to outlast the trends, the brands, and the conventional wisdom that premium carry has to mean heavy carry.

Strike Series is a full-size horizontal bifold, designed for back pocket, jacket, or suit carry. Full-size EUR/USD bills, traditional carry format. Flex Series is a compact vertical bifold, designed specifically for front pocket carry, narrower footprint.

The Strike Series is designed for traditional carry positions. Back trouser pocket, inner jacket pocket, or suit breast pocket. The full-size horizontal bifold format sits naturally in any of these positions. For front pocket carry, see the Flex Series.
