Some good recommendations above, BUT camo is for hunters.
Sure I own some, but Camo is for hunters in the vast majority of field scenarios. Technical mountain-hunting upper-end hunting apparel and gear companies have been making gear for 5-10 years, and some do a fine job of producing some genuinely quality pieces of equipment. But for my money (and often for much less of it!), I go with companies that have been making technical mountain-hunting upper-end backpacking apparel and gear companies for 10-50 years. Many of these companies have been refining their gear for decades, under pressure from gram-counters to improve their weight and other critical specs. Solid colors, sure there might be some neon ones to pick through, but frankly - even some of those work well in the field. Packs are the one item that I still have more faith in a company like Stone Glacier or Kifaru, most backpacking applications aren't designed to carry heavy heavy loads.
Some companies to check out are Stoic (their merino gear is quality and cheap and from 50-70% cheaper than companies like First Lite; their Hadron puffy is freaking awesome as well), Marmot (their PreCip gear is an excellent fly-weight option that is a FRACTION of the high dollar camo options), Helly Hansen gear can NOT be topped for more dreadful wet weather conditions, Target carries Champion C9 Golf pants (less than $30, indestructible poly/nylon mixture, less than 10 ounces for my M size, and available in flat colors like khaki and slate), I could list many more.
Good places to look...The Clymb, Steep and Cheap, Backcountry.com, frequently check the Deals thread on BackpackingLight.com, Sierra Trading Post can still cough up a good deal every now and then on base layers and wool blend socks (not as good as it used to be though).
