Guardians of the City™ Duty T-Shirt | SF Sheriff's Office: 175th Anniversary Edition

Pure Zero™ IGNITE Spec | Designed by Fenix Society™

175 YEARS OF HISTORY. ZERO COMPROMISE ON SAFETY.

The era of the lowest bidder t-shirt is officially retired. Since 1850, the San Francisco Sheriff’s Office has stood as a pillar of the City by the Bay. To honor this 175-year legacy, Fenix Society™ didn’t just design a commemorative shirt—we engineered a new technical standard for the modern Deputy.

The SF Sheriff's Office 175th Anniversary Edition is the debut release in The Pure Zero™ Professional T-Shirt Series. Designed by Fenix Society™ to disrupt a stale industry, this platform replaces toxic, boxy relics with a professional foundation built for health, safety, and discipline.

THE QUESTION THE "LOWEST BIDDER" WON’T ANSWER

As a Guardian, you size up every scene for hazards. It is time to size up your shirt:

• Is it Clean? Most departmental shirts are treated with hidden "forever chemicals" (PFAS). Ours is lab-verified bio-safe.

• Is it Professional? A sagging, twisted collar is a discipline failure. Our Pure Zero™ IGNITE spec holds its shape through the entire 24-hour watch.

• Is it Honorable? This shirt was designed by Fenix Society™ to support your history and your tribe, not a corporate boardroom.

STRUCTURED FIT & MODERN DIVERSITY

We’ve retired the shapeless "sock-fit" tube—a 60-year-old design that ignores the actual diversity of form and fit on today’s front line.

• Side-Seamed Architecture: An intentional, ground-up redesign by Fenix Society™ engineered to provide a sharp, athletic silhouette for every body type.

• Dimensional Stability: This shirt stays centered and stays tucked. No more flimsy fabric that twists and warps after the first wash.

TECHNICAL FABRIC: THE PURE ZERO™ IGNITE SPEC

This isn't your average shirt. It is a breathable shield designed for the high-stress demands of the watch:

• Mid-Weight Power: 5.3 oz weight provides the perfect balance of rugged durability and daily comfort.

• Premium Composition: 100% high-density combed cotton (28-singles) ensures a smooth finish that meets the NFPA 1975 specification for thermal safety.

• Thermal Integrity: Engineered to ensure it won't melt, drip, or produce toxic fumes under ballistic armor or high-heat conditions.

• Battle-Ready Construction: Features premium neck ribbing, shoulder-to-shoulder tape, and double-needle hems. Preshrunk to ensure the fit you buy is the fit you keep.

ZERO-TOXIN PRINTING

We protect the graphics as much as the fabric.

• PFAS-Free Inks: We verify that the 175th Anniversary graphics are printed with 100% PFAS-free ink.

• No Chemical Glues: We never use chemical pre-treatments or adhesive glues to bond our graphics, ensuring zero toxic off-gassing against your skin.

THE TRIPLE-SEAL OF INTEGRITY

• BIOLOGICAL (OEKO-TEX®): Lab-verified free from PFAS, heavy metals, and toxic surfactants.

• HUMAN (amfori BSCI): Built in audited facilities to ensure fair labor and safe conditions.

• ENVIRONMENTAL (BCI): Sourced via the Better Cotton Initiative to protect the environment we serve.

THE MISSION: HONORING THE PAST, INSPIRING THE FUTURE

This isn't just a purchase; it’s an investment in the legacy of the badge.

Over 80% of the profits from this series go directly back toward supporting our City and the Guardians of the City Museum and Safety Learning Center. By choosing the Pure Zero™ IGNITE spec designed by Fenix Society™, you are directly funding the preservation of our storied history.

These funds ensure that the artifacts, stories, and sacrifices of those who came before us are never forgotten. Most importantly, they allow us to use that history to inspire the next generation of first responders and leaders in civic service, ensuring the bridge of discipline and honor carries the City forward for the next 175 years.

HONOR THE HISTORY. PROTECT YOUR FUTURE. RISE TO THE STANDARD.
