Under Armour Inc., the Baltimore-based performance apparel maker, beat Wall Street analysts' expectations by posting higher than expected earnings for the first quarter of 2011. It also boosted its revenue and profit forecasts for the full year.
The company said Tuesday that it saw strength in sales of men's, women's and youth apparel lines in the first quarter, which ended March 31. In that quarter, Under Armour for the first time began selling a line of cotton T-shirts — the fabric is known as "Charged Cotton" — to target consumers who prefer cotton to synthetic workout apparel.
