This Bandit is crafted from 1 inch fold over elastic and a dry-fit material, which makes it super durable and climate resistant. Bandits are meant to keep your priceless memento safe in its hidden zipper compartment.
The Heavy Duty fits differently than the other Bandit options. It is a larger fit & feels more like a sweat band than an accessory. The pocket size is the same size. The s/m Heavy Duty is perfect for your wrist or forearm, the m/l is much larger. You may be able to fit the m/l further up your arm if you prefer the Bandit on your forearm or bicep.
