2. A pad according to claim 1 wherein the grooves (13) extend across the side edges of the core.

3. A pad according to claim 1 or 2 which is profiled in three dimensions so as to have front to rear
curvature as well as sidewards curvature (Fig. 6).

4. A pad according to claim 1, 2 or 3 wherein the core is provided with an insert (12) of lower density foam in that surface which in use contacts a user's body.

5. A pad according to any preceding claim wherein the core is provided with a fabric cover.

6. A pad according to claim 1 wherein the core (10) has four regions:

(i) a broad end region (A) which is relatively

intended to be attached to a rucksack;

(ii) continuing therefrom, a region (B) of slight sideways curvature provided with a plurality of grooves (13) in one or both surfaces;

(iii) continuing therefrom, a region (c) more
pronounced sideways curvature provided with an insert (12) of lower density in its front surface and with further transverse grooves

8. A pad according to claim 7 wherein an insert of lower density foam is provided in the central region in the concave surface which in use contacts a user's body.

9. A rucksack comprising a fabric sack (22), a supportive frame comprising at least one substantially rigid vertical member (21) mounted at the rear of sack, a harness comprising shoulder pads (10, 20) mounted on said frame and associated straps (23, 25), a lumbar pad (27), and a hip belt (28, 29), characterised in that the shoulder pads (10, 20) are joined together symmetrically in the scapular region (15) and each comprises an elongate moulded foam plastics core formed with a plurality of transverse grooves in at least that surface which in use contacts the user's body.
