KNKG HERITAGE Collection — Timeless Gym Bags Crafted in Leather
For the active man who wants more than performance, the HERITAGE Collection delivers timeless leather gym bags that blend strength, style, and lasting character. Built from premium full-grain leather with KNKG’s proven functionality, these are the gym bags that age beautifully while carrying everything you need.
Why Leather?
Leather isn’t just about looks — it’s one of the toughest natural materials you can train and travel with. Full-grain leather delivers the durability and resilience to handle heavy use, while softening and draping naturally over time.
- Durability: Built to withstand years of training, travel, and daily carry.
- Supple Feel: Softens and drapes with use, making each bag more comfortable the longer you own it.
- Style: Ages with a unique patina that gives every bag timeless character.
The HERITAGE Collection combines rugged performance with lived-in style, making it the gym bag line that looks as good outside the gym as it performs inside it.

The Inspiration Behind HERITAGE
The HERITAGE Collection takes inspiration from the classic leather equipment of old gyms — speed bags, heavy bags, and gloves that endured for decades. These pieces weren’t flashy, but they were tough, dependable, and only got better with age.
That same spirit lives in HERITAGE. Each bag is built from full-grain leather that softens over time, molds to your use, and develops a unique patina. Like the equipment that inspired it, these bags are made to perform on day one — and still feel just as reliable on day one thousand.

- Each bag develops a unique patina and soft character over time
