I've been putting my kit back together slowly over the last little bit. There's definitely area and season appropriate gear. Since my back and shoulders are a bit beat up nowadays, I'm learning the benefits of going lighter. Multi-function gear is always good. The most important things: stay dry, stay warm, stay hydrated and well fed, TAKE CARE OF YOUR FEET!!!...The army's answer for everything: Drink water, change your socks.
Most of my kit is milsurp or old issue gear I still have lying around. Its heavy, but its bomb-proof. I'm trying to find some good weight compromises now. I bought a digital fish scale from Gander Mountain to weigh all my gear. I'm trying to get my base between 20-25lbs for a week-long loadout. I'm sitting at about 30lbs right now, but my ol' ruck is 8.6lbs on its own. With all the heat and humidity (I don't do cold weather well and only get outdoorsy in the warmer months) I prefer external frame packs. Been looking at a Kelty 3950, it would drop a little over 3lbs off my base weight just from switching packs.
As for gear, I'm slowly swapping in civvie stuff. Sweatwicking clothes and convertible nylon cargo pants (that way I don't have to carry an extra pair of shorts). I usually stick to UnderArmor and Northface. An aluminum alcohol stove (been eyeing the Trangia 28). I've got the usgi MSS bags (I love those things) and pack the patrol bag and gortex cover. My tent consists of USGI poncho, bungee and para cord, and a few aluminum stakes. I always carry a Kershaw Blur pocket knife, Leatherman Wave, and Surefire E1L Outdoorsman flashlight even in my everyday wear. I back those up camping with a cold steel SF shovel and a 5.5" kabar. The blades aren't really necessary for trailwork, but very much needed if you're gonna off-trail or into less maintained areas. You can never have enough 550cord or 100mph tape

.
My camping list is so similar to the old packing lists for going out into the field, its funny. Just gotta swap to lighter gear and I ditched the combat related equipment.
On the knives, I really recommend the coldsteel shovel. Serves multi-purpose as my hatchet/machete/hammer/shovel.

I actually have 2 packs:
Good Ol' Alice. Heavily modified. Similar to the Hellcat ruck:
Share your cheap yet potentially valuable tricks.... - AR15.COM
My extended range, all season bag (or zombie apocalypse gear

) She may be a bit thick, but you can always count on her. I've seriously considered swappin' her out for a Kelty Trekker 3950 (which I would of course modify, like my pack even with my shoulders so I don't have to worry about snaggin' it on every tree limb in the forest, civvie ex. frames sit up way too high, plus better center of gravity for my tall, lanky ass). I just can't bring myself to give up that 'toss her out of the back of plane into a minefield and she'll just shrug it off' durability.
Its a little empty right now, been going through my gear and revising my loadout.
The 2nd is my 'Daypack'. A modified Camelback Mule I've had for ages. I actually have enough gear, food, and water in there that I could get lost in the woods for a couple of days and be perfectly fine. Full load-out comes in at about 15lbs. This is what you'll most often find me hiking around with.
I've actually got a lightweight sleep system in there. The same poncho hooch I mentioned earlier and a woobie (poncho liner) for warmth(plus a space saver blanket in my medical pouch to supplement). Otherwise known as a Ranger Roll.
