CLARIFICATION : At the request of the Spanish company Original Buff S.A., we inform readers that the headwear products we identified as “buffs” in the SGI Europe issue of Jan. 11 are not genuine Buff products. Original Buff S.A. insists that it is the only manufacturer of Buff branded headwear products. The Buff trademarks are the property of Original Buff S.A., which didn't authorize the use of the word “buff” in the article in question. For more information on Buffs products and the intellectual property rights of Original Buff S.A., readers can visit its official website, www.buff.com.
