If you are buying him a driver or fairway wood the best thing to do is ask him, because I cannot tell you what loft is ideal for his ball flight or what he prefers. You could have a quick look in his bag and see what loft he uses and then get a replacement.
If he doesn't know you could get him custom fit at your local Golf shop, this is an inexpensive process but has clear benefits.

Height and Distance
Loft refers to the angle of the golf club's face from the vertical axis. The loft of a club imparts varying degrees of backspin on the ball, making it fly higher and shorter, as in irons and wedges, or lower and longer, as in woods and drivers. The standard sand wedge has a loft ranging from 52 degrees to more than 60; drivers usually have a loft of around 9-10 degrees.

Loft
This is a 3 hybrid, usually with 20-22 degrees of loft.
The number relates to the loft of the club and the length of the shaft. For example a 3 iron has the lowest loft and longest shaft. A 7 irons has more loft and a shorter shaft than the 3 iron.
