Adaptive camouflage

1. An apparatus for retaining camouflage material, the apparatus comprising:

a frame comprising a front surface and a back surface, the frame configured to distribute pressure across the back surface from camouflage material retained against the front surface;

at least one retention device coupled to the frame, the at least one retention device configured to retain camouflage material against the front surface of the frame, the at least one retention device comprising an elastic band, the elastic band comprising a front layer and a back layer, the front layer permanently fixed to the back layer in at least two positions to form one or more loops between the at least two positions, wherein at least one of the one or more loops is positioned entirely in front of the frame;

an array of extension members extending from the back surface of the frame, the extension members protruding from the back surface of the frame at a height sufficient to allow airflow between the frame and a wearer; and

at least one vent opening formed in the frame, the vent opening comprising a channel extending between the front surface and the back surface of the frame.

2. The apparatus of claim 1 , wherein the frame is sufficiently flexible to conform to a part of a wearer's body.

3. The apparatus of claim 2 , wherein the frame is sufficiently stiff to resist indentation due to pressure from camouflage material.

4. The apparatus of claim 1 , wherein the frame is integrated with an article of apparel.

5. The apparatus of claim 1 , wherein the frame comprises two transverse portions and a longitudinal portion, the longitudinal portion extending between the two transverse portions, and the at least one retention device comprises two elastic bands, each elastic band comprising a middle portion coupled to one of the two transverse portions of the frame, and end portions extending beyond the frame for fastening around an object.

6. The apparatus of claim 1 , wherein the frame comprises three sides and the at least one retention device comprises an elastic band extending along the three sides to form a triangle.

7. The apparatus of claim 1 , wherein the back surface comprises an array of recesses.

8. The apparatus of claim 1 , wherein the camouflage material comprises natural plant material.

9. The apparatus of claim 1 , wherein the camouflage material comprises artificial plant material.

10. The apparatus of claim 9 , wherein the artificial plant material comprises a collector for one or more of solar energy, motion energy, and water.

11. The apparatus of claim 1 , further comprising a clip configured to attach the frame to a webbing strap.

12. The apparatus of claim 11 , wherein the clip comprises a triangular portion rotatably engageable with a triangular opening in the frame.

13. A system for retaining camouflage material, the system comprising:

at least one frame comprising a front surface and a back surface, the frame configured to distribute pressure across the back surface from camouflage material retained against the front surface; and

two elastic bands, each elastic band comprising a middle portion coupled to the frame for retaining camouflage material against the front surface of the frame and end portions extending beyond the frame for fastening around an object, wherein at least one of the elastic bands comprises a front layer and a back layer, the front layer permanently fixed to the back layer in at least two positions to form one or more loops between the at least two positions, wherein at least one of the one or more loops is positioned entirely in front of the frame,

wherein the frame is sufficiently flexible to conform to a part of a wearer's body.

14. The system of claim 13 , further comprising at least two additional elastic bands, a color of the at least two additional elastic bands differing from a color of the two elastic bands coupled to the frame.

15. A method for retaining camouflage material, the method comprising:

providing a frame comprising a front surface and a back surface, the frame configured to distribute pressure across the back surface from camouflage material retained against the front surface;

providing at least one retention device coupled to the frame, the at least one retention device comprising two elastic bands, each elastic band comprising a middle portion coupled to the frame for retaining camouflage material against the front surface of the frame and end portions extending beyond the frame for fastening around an object, wherein at least one of the elastic bands comprises a front layer and a back layer, the front layer permanently fixed to the back layer in at least two positions to form one or more loops between the at least two positions, wherein at least one of the one or more loops is positioned entirely in front of the frame;

providing at least one vent opening formed in the frame, the vent opening comprising a channel extending between the front surface and the back surface of the frame;

using the retention device to retain camouflage material against the front surface of the frame; and

wearing the frame.

16. The method of claim 15 , further comprising adapting to new surroundings by replacing the camouflage material with new camouflage material.
