Numnahs and saddle pads are relatively low-risk second-hand purchases, but there are still a few things worth checking before you hand over your cash:

• Padding thickness - give the pad a good squeeze. If the padding has gone flat and thin, it's past its best. A numnah that's lost its cushioning isn't doing its job anymore, no matter how clean it looks.
• Velcro tabs - most modern numnahs use velcro to attach to the saddle. Check the velcro still grips firmly. Worn-out velcro means the pad will slip during riding, which defeats the purpose entirely.
• Girth strap loops - the loops that your girth straps pass through need to be intact and securely stitched. Torn or missing loops are a nuisance and can cause the pad to bunch up under the saddle.
• Stains and discolouration - this is mostly cosmetic. Sweat stains are normal on used pads and often wash out. If you're buying for everyday schooling rather than shows, a few marks shouldn't put you off, especially at a lower price.

Overall, numnahs offer fantastic value on the second-hand market. Because they're so affordable to begin with, sellers often price them very reasonably. It's not unusual to pick up a quality pad for the price of a bag of carrots and a coffee.
