N'hay Gear - Hay Sling
The humble Hay Sling is the one piece of kit you didn't know you needed until you have one.
Use it for taking hay out and keeping yourself rather clean of course. Its also great to bring rugs in and out to or from your horse. It collects firewood very well and can wrap up a hot mess of bridle, saddle blanket and lead ropes for carting to gear up easily.
I'm sure you will find even more uses. Just get one. Or three. You'll be so glad you did.
