How it compares in Gym Bags
Across the 29 rated gym bags products we track, the typical score is 4.4 out of 5. This one sits at 4.6, which is around the middle of the category. Ratings alone will not separate it from its rivals here, so price and the specifics below matter more than the star count. That places it first of the 29 we rank here.
It carries 16,127 ratings against a category median of 921. A rating from a large base is harder to distort and tends to hold up over time, so a high score here means more than the same score on a new listing.
On price it sits in the upper third of a category running from £3.95 to £26.49, where the midpoint is about £13.99. It is priced above the field and rated above it too, so the premium is at least matched by how buyers rate it.
