The chest strap arrangement of claim 1, wherein the region of greater cross sectional thickness is located at an inner wall of the at least one substantially horizontal slot of the at least one of the first buckle and the second buckle. 3. The chest strap arrangement of claim 1, wherein the cross sectional thickness of the at least one of the first buckle and the second buckle increases in a direction towards the outer end area. 4. The chest strap arrangement of claim 1, wherein the inner end area of at least one of the first buckle and the second buckle comprises a first attaching structure, the chest strap further comprising a second attaching structure engaged with the second portion of the strap member and configured to operatively interact with the first attaching structure. 5. The chest strap arrangement of claim 1, further comprising a frame member having at least one opening and positioned adjacent a rear surface of at least one of the first buckle and the second buckle, wherein at least one of the first torso strap and the second torso strap extends through the at least one opening of the frame. 6. A chest strap arrangement for an attachable arrangement removably attachable to a user and having a first torso strap and a second torso strap, the chest strap arrangement comprising: a strap member with a first portion and a second portion;a first buckle having an inner end area and an outer end area, and at least one substantially horizontal slot extending through at least a portion of the outer end area through which the first torso strap extends, wherein the first buckle is directly or indirectly engaged with the first portion of the strap member; anda second buckle having an inner end area and an outer end area, and at least one substantially horizontal slot extending through at least a portion of the outer end area through which the second torso strap extends, wherein the second buckle is directly or indirectly engageable with the second portion of the strap member;wherein the inner end area of the second buckle comprises a first attaching structure, the chest strap further comprising a second attaching structure engaged with the second portion of the strap member and configured to operatively interact with the first attaching structure, andwherein the second attaching structure is disposed at an end of the strap member;wherein at least one of the first buckle and the second buckle has an inner wall with a sloped portion extending in a direction substantially parallel to the at least one substantially horizontal slot such that the cross sectional thickness of at least a portion of the outer end area of the at least one of the first buckle and the second buckle is greater than the cross sectional thickness of at least a portion of the inner end area of the at least one of the first buckle and the second buckle. 7. The chest strap arrangement of claim 6, wherein the first attaching structure and the second attaching structure are releasably engageable. 8. The chest strap arrangement of claim 6, wherein the first attaching structure comprises a substantially vertical slot, and the second attaching structure comprises a plate member, which, when inserted through the substantially vertical slot at least partially bears against a surface of the second buckle. 9. The chest strap arrangement of claim 8, wherein the slot is formed by a first slot portion connected to and vertically misaligned with a second slot portion, thereby forming a shaped slot. 10. The chest strap arrangement of claim 6, wherein the first attaching structure comprises a shaped projection, and the second attaching structure comprises a receiving member having a body and defining an insertion slot configured to at least partially receive the shaped projection therein, thereby engaging the first attaching structure and the second attaching structure. 11. The chest strap arrangement of claim 10, wherein the receiving member comprises an actuatable release mechanism configured to releasably engage the shaped projection at least partially within the insertion slot. 12. The chest strap arrangement of claim 11, wherein the release mechanism is actuated by at least one actuation member positioned on the body of the receiving member for releasing the shaped projection from the receiving member. 13. The chest strap arrangement of claim 6, further comprising a frame member having at least one opening and positioned adjacent a rear surface of at least one of the first buckle and the second buckle, wherein at least one of the first torso strap and the second torso strap extends through the at least one opening of the frame. 14. A chest strap arrangement for an attachable arrangement removably attachable to a user and having a first torso strap and a second torso strap, the chest strap arrangement comprising: at least one strap member;a first buckle having an inner end area and an outer end area, and at least one substantially horizontal slot extending through at least a portion of the outer end area through which the first torso strap extends, wherein the first buckle is directly or indirectly engaged with a portion of the at least one strap member;a second buckle having an inner end area and an outer end area, and at least one substantially horizontal slot extending through at least a portion of the outer end area through which the second torso strap extends, wherein the second buckle is directly or indirectly engaged with a portion of the at least one strap member; anda frame member positioned adjacent a rear surface of at least one of the first buckle and the second buckle;wherein at least one of the first buckle and the second buckle has an inner wall with a sloped portion extending in a direction substantially parallel to the at least one substantially horizontal slot such that the cross sectional thickness of at least a portion of the outer end area of the at least one of the first buckle and the second buckle is greater than the cross sectional thickness of at least a portion of the inner end area of the at least one of the first buckle and the second buckle. 15.
