A garment with a flexible fabric shell has a pocket or vent opening with a resealable closure such as a zipper, snaps, or hook and loop fasteners, which is operable between a closed position, in which the opening in the shell is closed, and an open position, in which the opening in the shell is revealed. A resilient spring member of springy plastic, composite, metal or other material is mounted to the fabric around the opening, and has two arms which have portions which are displaced vertically from one another when the closure is open, but which are resiliently compressed into a common plane when the closure is sealed. Each time the closure is opened, the spring member urges portions of the shell on either side of the flap apart, to thereby enlarge the area of the opening and permit access or air flow therethrough.

1. A garment comprising:a shell formed of a flexible substrate, and having an opening therein, the opening extending in a first direction, wherein the shell has portions forming a first side flap on one side of the opening, and a second side flap on an opposite side of the opening; a resealable closure having portions affixed to the first side flap, and portions affixed to the second side flap, the closure being operable between a first closed position, in which the opening in the shell is closed, and a second open position, in which the opening in the shell is revealed; and a resilient spring member first arm which engages the first side flap and a resilient spring member second arm which engages the second side flap, the spring member first arm being positioned in a second direction across the opening from the second arm, wherein a first plane is defined by the first direction and the second direction, and wherein the spring member is formed such that portions of the first arm are spaced from portions of the second arm in a direction perpendicular to the first plane when the spring member is undeformed, and when the closure is in the closed position, the first arm is brought into approximately the same plane as the second arm, such that in the second open position, the spring member urges portions of the first flap away from portions of the second flap in a direction perpendicular to the first plane to thereby enlarge the area of the opening. 2. The garment of claim 1 wherein the spring member first arm is connected to the second arm by a first connecting section, and wherein the spring member first arm has a free end spaced from the first connecting section, and the spy member second arm has a free end spaced from the first connecting section.3. The garment of claim 1 wherein the spring member first arm is connected to the second arm by a first connecting section, and wherein the spring member has a second connecting section spaced from the first connecting section, and the first arm and the second arm extend between the first connecting section and the second connecting section.4. The garment of claim 1 wherein the closure is integrally formed with the spring member.5. The garment of claim 1 wherein the closure is fixed to the flexible substrate of the shell, and the spring member is separately fixed to the flexible substrate of the shell.6. The garment of claim 1 wherein the closure is selected from the group consisting of a zipper, at least one snap fastener, at least one button, at least one tie, and a hook and loop fastener.7. A garment comprising:a shell formed of a flexible substrate, and having an opening therein, the opening extending in a first direction, wherein the shell has portions forming a first side flap on one side of the opening and a second side flap spaced in a second direction across the opening from the first side flap, the first direction and the second direction defining a plane; a resealable closure having portions affixed to the first side flap, and portions affixed to the second side flap, the closure being operable between a first closed position, in which the opening in the shell is closed, and a second open position, in which the opening in the shell is revealed; and a resilient spring member first arm which engages the first side flap and a resilient spring member second arm which engages the second side flap, the spring member first arm being positioned in the second direction across the opening from the second arm, wherein in the second open position, the spring member first arm projects downwardly below the plane and has an upwardly opening concave curvature, and the spring member second arm projects upwardly above the plane and has a convex curvature, such that portions of the first arm are spaced from portions of the second arm in a direction perpendicular to the first plane when the spring member is undeformed, and when the closure is in the closed position, the fist arm is brought into approximately the same plane as the second arm, such that in the second open position, the spring member urges portions of the first flap away from portions of the second flap in a direction perpendicular to the first plane to thereby enlarge the area of the opening. 8. The garment of claim 7 wherein the first arm is connected to the second arm by a first connecting section, and wherein the spring member first arm has a free end spaced from the first connecting section, and the spring member second arm has a free end spaced from the first connecting section.9. The garment of claim 7 wherein the first arm is connected to the second arm by a first connecting section, and wherein the spring member has a second connecting section spaced from the first connecting section, and the first arm and the second arm extend between the first connecting section and the second connecting section.10. The garment of claim 7 wherein the closure is integrally formed with the spring member.11. The garment of claim 7 wherein the closure is fixed to the flexible substrate of the shell, and the spring member is separately fixed to the flexible substrate of the shell.12. The garment of claim 7 wherein the closure is selected from the group consisting of a zipper, at least one snap fester, at least one button, at least one tie, and a hook and loop fastener.13. The garment of claim 7 wherein the the first arm is a narrow strip of plastic material approximately {fraction (1/16)} inch thick.14. The garment of claim 7 wherein the spring member is formed of nylon.15. A garment comprising:a shell formed of a flexible substrate, and having an opening therein, the opening extending in a first direction, wherein the shell has portions forming a first side flap on one side of the opening, and a second side flap on an opposite side of the opening; a resealable closure having portions affixed to the first side flap, and portions affixed to the second side flap, the closure being operable between a first closed position, in which the opening in the shell is closed, and a second open position, in which the opening in the shell is revealed; and a resilient spring member mounted to the shell, the spring member having a first arm which engages the first side flap and a second arm which engages the second side flap, the spring member fir arm being positioned in a second direction across the opening from the second arm, wherein a first plane is defined by the first direction and the second direction, and wherein the spring member is formed such that portions of the first arm are spaced from portions of the second arm in a direction perpendicular to the first plane when the spring member is undeformed, and when the closure is in the closed position, the first arm is brought into approximately the same plane as the second arm, such that in the second open position, the spring member urges portions of the first flap away from portions of the second flap in a direction perpendicular to the fist plane to thereby enlarge the area of the opening.
