The bag is well made. However, it is a too small for average adult TUSA fins. More ideal for children's fin and snorkel set. Moreover, the front compartment is too small for anything other than a wallet, your sunglasses, or a pair of earplugs.
The bag measures 20'' in Length, 11'' base, 6'' top, and 5'' thick.
The front compartment is 7-1/2'' wide, 5-1/2'' tall, and 1'' deep.
