A TIMELESS ATHLETIC BAG THAT OFFERS THE SAME PERFORMANCE ON DAY ONE THOUSAND AS IT DID ON DAY ONE.
My first memories of training were of leather speed balls and well-worn heavy bags. These pieces had hung in the gym since the turn of the previous century and yet were still the toughest things in the gym. Twenty-five years later, I still find inspiration in the smell of leather and the feel of an old leather heavy bag. I want to recreate that feeling, that gym atmosphere before the time of elliptical trainers, smartwatches, and large, clunky treadmills.
Leather yields strength and longevity. It's timeless and holds a sense of heritage. This is a bag I'm proud to carry both inside and outside the gym. One that will wear in over time, rather than wear out. A bag that will only get better with age, developing a unique patina as is it moulds to me and my training.

Top notch duffle, I really like the rectangle shape rather than a typical oval duffle bag. This creates for more room inside and looks better.

My husband had been eyeing this bag since the last model sold out. I could tell he really loved it, so I ordered the new version ; he loved it! It’s so functional for his professional bodybuilding. Lots of room for bulky items, and let’s not forget how sexy the bag is.
