Absolutely overwhelmed with this heated gilet. I’ve looked at hundreds, tried on many equine heated gilets but the price was extortionate. I then found this one, https://amzn.to/3ZVQrGv, on Amazon. It was originally £44.95 but reduced to £28.95 on Black Friday. I’ve since purchase a couple more as Christmas presents for horsey friends. Without altering the zippers the gilet is a size 10-12 but it has four hidden zippers so can expand to a larger side.

I never take this gilet off. I have two batteries which I alternate between – so one could be on charge. I purchased the batteries off Amazon for £6.99. https://amzn.to/3PmwEuF
