At Eastern Mountain Sports we've always worked hard to offer our customers amazing value for money. We do this by carefully designing our own brand products and then having them manufactured to our exacting standards, often in the same factories as other more expensive brands. We then cut out the middleman, selling direct to our customers through our own stores and websites and pass the savings on to you.
Often we offer this exceptional value through multi-buys or special purchases. Sometimes we also show a "comparable price" which is the price our buying and sourcing teams believe a product of comparable quality would be offered at full retail price by other leading brands. It is not intended to reflect a former price at which the product has sold.
