I've recently used some clothing that I like very much for their respective practicality, and thought I'd pass on what I like about them:
Arborwear Tech Pants.
Unlike most synthetic "trail pants", which tend to be made of thin material more suitable for hot weather or hiking on trails, I was glad to find a pair of pants that have their emphasis on toughness. They are cargo-style with big pockets, double-fronted material on the thighs, and gussetted crotch. The material is soft and quiet, and not at all "swishy" like some nylon pants. Comes in several practical solid colors - grey, brown, etc. Another plus: they come in lots of waist and inseam sizes like blue jeans do, so if you're hard to fit (like me), you should be able to get the size you need. Somewhat pricey at $70, but in my opinion worth it. Two thumbs up.
Cabela's Worsterlon shirt.
Got one on sale at Cabela's for 19 bucks - usually, they're around $30. Again, a very tough, warm, long-sleeved shirt, made of synthetic (quick drying) material. A very nice alternative to a wool shirt.
