LeMieux Merino+ Half Lined GP/Jump Numnah Black/Black. The LeMieux Merino+ Half Lined Numnah is half lined with pure Australian Merino Lambswool that has been removed from its skin and integrated with a unique backing fabric that can expand and contract whilst retaining its inbuilt strength. The unique backing fabric aids wicking and moisture control, minimises temperature variations and the density of the Merino+ wool moulds to the horse's back without adding too much bulk. Merino+ overcomes the common issues associated with traditional lambskin pads as it will not dry out and become brittle and can withstand the rigors of regular washing and daily use.

The LeMieux Numnah offers Merino+ Lambswool under the seat area to prevent pressure points while allowing the rider to maintain a close leg contact. The LeMieux Half Lined Numnah features a clear spine and a sweeping swan neck that relieves pressure, allows airflow and helps keep the numnah secure. The LeMieux Half Lined Numnah features the signature girth protection areas and double Velcro fastenings to ensure easy fitting. Available in Medium (16-17) and Large (17. 5â€ -18â€ ).
