- Stick measure — from withers to base of tail along the back
- Upper width — chest opening at the front of the blanket
- Bottom width — drop length from spine to lower edge

If between sizes, size up — a blanket that's too tight rubs at the chest and shoulders. The blanket should sit clear of the wither, cover the full back to the base of the tail, and the front buckles should fasten without straining.
The Nena UV is HV Polo's combined sun and fly turnout rug — a two-fabric build designed for horses who live out in bright weather and need both UV protection and fly cover in one sheet.
The top layer is a UPF50+ fabric that reflects the sun's rays rather than absorbing them, helping keep coat colour from bleaching and stopping the horse overheating in direct sunlight. The bottom half drops to a lightweight breathable mesh, which keeps airflow moving and gives the fly protection without trapping heat. A soft polyester lining runs through the chest and over the mane area to stop rubbing on the coat.
The neck piece detaches, the belly flap is adjustable, and there's an extra-long tail flap for full hindquarter cover when the horse is grazing or moving around the field.
Main material: 100% Polyester
Closure: Velcro and buckles
