Touch fastener products

1. A touch fastener comprising:

an elongated base having multiple segments connected by articulable joints, each segment having upper and lower surfaces and a plurality of touch fastener elements extending from the lower surface of the base;

a flexible barrier extending across at least one articulable joint between adjacent base segments; and

a magnetically attractable material disposed along a center region of the upper surface of the base.

2. The touch fastener of claim 1 , wherein the base defines a pair of first and second notches in opposite longitudinal edges of the base at the articulable joint.

3. The touch fastener of claim 2 , wherein the barrier defines a slit in through a longitudinal edge of the flexible barrier and aligned with one of the notches at the articulable joint.

4. The touch fastener of claim 1 , further comprising multiple discrete barrier segments, each barrier segment extending across at least one respective articulable joint.

5. The touch fastener of claim 1 , further comprising a flexible compressible gasket secured to the lower surface of the base.

6. A touch fastener comprising an elongated base having upper and lower surfaces, a plurality of touch fastener elements extending from the lower surface of the base, and a magnetically attractable material disposed along a center region of the upper surface of the base, wherein the base defines a series of spaced apart pairs of opposite notches in its longitudinal edges and forming respective articulable base joints, adjacent pairs of notches defining respective base segments therebetween;

wherein the notches are each sized with respect to an overall width of the base such that, when one of the articulable joints is flexed to close one of its corresponding notches, the other of its corresponding notches opens only to a longitudinal gap dimension less than about 0.5 millimeter.

7. The touch fastener of claim 6 , further comprising a flexible barrier extending across at least one articulable joint between adjacent base segments.

8. The touch fastener of claim 6 , wherein the base defines a pair of first and second notches in opposite longitudinal edges of the base at the articulable joint.

9. The touch fastener of claim 6 , further comprising a barrier extending across at least one articulable joint between adjacent base segments, the barrier defines a slit in through a longitudinal edge of the flexible barrier and aligned with one of the notches at the articulable joint.

10. The touch fastener of claim 6 , further comprising multiple discrete barrier segments, each barrier segment extending across at least one respective articulable joint.

11. A touch fastener comprising:

an elongated base having multiple segments connected by articulable joints, each segment having upper and lower surfaces and a plurality of touch fastener elements extending from the lower surface of the base; and

a flexible barrier extending across at least one articulable joint between adjacent base segments;

wherein the base defines a pair of first and second notches in opposite longitudinal edges of the base at the articulable joint, and the barrier defines a slit in through a longitudinal edge of the flexible barrier and aligned with one of the notches at the articulable joint.

12. A touch fastener comprising:
