Lot JG-31 - Tweedy Prison Cap - Gray

$ 85.00

The Lot JG-31 Tweedy Prison Cap pulls from a very specific piece of American history, referencing the caps issued to prisoners at the Portsmouth Naval Prison during the 1930s and 1940s. It’s a simple, utilitarian design, but one that carries a lot of quiet character, especially when executed with the level of care John Gluckow is known for. This isn’t a novelty reproduction, it’s a thoughtfully balanced cap that feels authentic without being costume-like.

Made from a wool-blend tweed, the fabric adds texture and visual depth while remaining soft and wearable. The six-panel construction and full brim give it a classic profile that works just as well with workwear as it does with cleaner, pared-back outfits. We love the immediate upgrade this gives to any outfit. 

  • 90% wool / 10% nylon tweed
  • Six-panel construction
  • Full brim
  • One size
  • Head circumference: 21.6"
  • Crown height: 4.7"
  • Brim length: 2.6"
  • Made in Japan

Fit Notes: These are made with a one-size-fits-most denotation. That fit with a slightly shallow brim. They should fit well on medium-large head sizes.
