I think this is a tough one to get right for someone else. DH's goggles feel like an ice-cream box on my face and he thinks mine rub his nose in a funny way. Would it be better to buy her a voucher for Ellis Brigham or Snow and Rock, or do a home-made one so you can take her shopping in the new year?
If you're intent on buying something, Decathlon have a good range of reasonable ones which should be easily exchanged. And there are some really good cheapy ones in Lidl this week (£10!)
