When you see clothing made of merino wool, you probably don't think of wearing it in the summer. But according to the company, it's actually the most comfortable fiber you can wear in the heat because it breathes better than synthetics. The Twizel Henley, part of Ibex Outdoor Clothing's new line of merino apparel for men, is a great-looking shirt that's perfect for a day out on the boat. It doesn't retain odor, because its fabric naturally regulates the body's temperature on a hot summer day by absorbing moisture vapor given off, also preventing that sticky, clammy feeling.  It even gives UV protection, naturally shielding your skin from the sun. Most merino clothing requires special care, but this shirt from Ibex is machine-washable - and even after throwing it in  the dryer, it will hold its original shape because of merino's natural stretch  quality. The shirt comes in six colors  and retails for $79. (800) 773-9647, www.ibex.com.
