a hand back portion configured to cover at least metacarpal bones of the ring finger, the middle finger, and the index finger of the hand on the back side of the hand, wherein the hand back portion comprises a moldable and hardenable material;

a wrist back extending from the hand back portion and configured to cover a back of an ulna and a back of a radius of the forearm, wherein the wrist back extension comprises a moldable and hardenable material; and

a wrist side extension extending sideways from the wrist back extension, the wrist side extension comprising a moldable and hardenable material configured to wrap about the ulna from the back side to the palm side of the forearm, wherein the wrist back extension and the wrist side extension are integrally formed as a single unitary panel;

a finger retainer extending from the hand back portion and configured to receive at least one of the middle, index and ring fingers of the hand; and

a flexible wrist strap extending from the wrist side extension, the flexible wrist strap being releasably connectable to a back of the wrist back extension.

2. The batter hand guard of claim 1 , wherein the hand back portion, the wrist back extension and the wrist side extension are integrally formed as the single unitary panel.

3. The batter hand guard of claim 2 further comprising an outer encasement enclosing the single unitary panel.

4. The batter hand guard of claim 3 , wherein the outer encasement is formed from a fabric material.

5. The batter hand guard of claim 2 , wherein the wrist back extension has a first width and wherein the hand back portion has a second width greater than the first width.

6. The batter hand guard of claim 5 , wherein hand back portion comprises a bent side portion configured to cover a side of the hand between the pinky and the ulna.

7. The batter hand guard of claim 1 , wherein the wrist side extension extends beyond the hand back portion by at least 1 inch.

8. The batter hand guard of claim 1 , wherein the hand back portion and the wrist back extension have a combined length of at least 4 inches.

9. The batter hand guard of claim 1 , wherein the hand back portion has an unbent width of at least 4 inches.

10. The batter hand guard of claim 1 , wherein the wrist side extension extends from a first side portion of the wrist back extension and has a terminal edge sufficiently spaced from a second side portion of the wrist back extension to facilitate sideways insertion of the wrist joint between the terminal edge and the second side portion of the wrist back extension.

11. The batter hand guard of claim 1 , wherein the moldable and hardenable material is moldable while being positioned on the hand and subsequently hardenable while positioned on the hand.

12. The batter hand guard of claim 1 , wherein the hand back portion is configured to be disengaged from the thumb so as to not encircle the thumb, facilitating articulation of the thumb relative to the backhand portion.

13. The batter hand guard of claim 1 , wherein the wrist side extension is configured so as to terminate along an edge on a pinky side of the index finger to form a wrist opening sized to sideways receive a wrist following hardening of the wrist side extension.

14. The batter hand guard of claim 1 , wherein the hand back portion comprises a second single unitary panel of a moldable and subsequently hardenable material, the second single unitary panel being distinct from the single unitary panel.

15. The batter hand guard of claim 14 , wherein the single unitary panel and the second single unitary panel have different pre-hardening and/or post hardening characteristics.

16. A batter hand guard comprising:

a single unitary panel formed from a moldable and bendable material and having an L-shape, the single unitary panel comprising a hand back portion, a wrist back extension extending from the hand back portion, and a wrist side extension extending sideways form the wrist back extension;

an encasement about the panel;

a finger retainer connected to the encasement proximate an end of the hand back portion; and

a wrist strap extending sideways from the wrist side extension for wrapping about a wrist,

wherein wrist side extension is moldable for wrapping the wrist strap extension about a side of an anatomical wrist and is hardenable for retaining a wrapped shape corresponding to a shape of the wrist.

17. The batter hand guard of claim 16 , wherein side portions of the panel forming the hand back portion are moldable for forming a trough shape about an anatomical hand and are hardenable to retain the trough shape.

18. A batter hand guard comprising:

a protective portion having an L-shape, the protective portion comprising a hand back portion, a wrist back extension extending from the hand back portion, and a wrist side extension extending sideways form the wrist back extension;

a finger retainer connected to the hand back portion; and

a wrist strap extending sideways from the wrist side extension for wrapping about a wrist,

wherein wrist side extension is rigid along its entirety and is curved to receive a side of the wrist, the side extension having a terminal edge sufficiently spaced from the wrist back extension to facilitate sideways insertion of the wrist between the terminal edge and the wrist back extension.

19. The batter hand guard of claim 18 , wherein the L-shape of the protective portion is formed from a single unitary panel member.

20. The batter hand guard of claim 18 , wherein the wrist side extension is formed from a moldable and subsequently hardenable material.

21. The batter hand guard of claim 20 , wherein the wrist side extension is coplanar with the wrist back extension and the hand back portion prior to being molded and hardened while being wrapped about a batter's wrist.

22. The batter hand guard of claim 18 , wherein the hand back portion, the wrist back portion and the wrist side extension are integrally formed as a single unitary panel and are rigid across the entirety of the panel.

23. The batter hand guard of claim 22 , wherein, the batter hand guard does not encircle the thumb, facilitating articulation of the thumb relative to the batter hand guard.
