1. A vapor adsorbing canister comprising:

a first sorbent;

a second sorbent; and

wherein during an adsorption or a desorption operation, the linear velocity of gases is higher in the second sorbent than in the first sorbent;

wherein the first sorbent and the second sorbent each individually have an incremental adsorption capacity of greater than 35 g n-butane/L between vapor concentrations of 5 vol. % and 50 vol. % n-butane, and

wherein the second sorbent is in the form of a sheet which has been stacked, rolled, wound, folded, laminated, or combinations thereof to form a sorbent material sheet product having a void volume of about 10% to about 25%.
