Hello, I'm new here to the forums and thought i'd throw up my current gear list here to get some input. Since we are "snowed in" here in Metro Detroit I have some time on my hands (probably one of the only perks of working in education).
I have backpacked for some time and recently got married and introduced my wife into the sport. Though I've had experience, my gear list was quite old, dating about ten years back to when I went to Philmont. So, we recently have acquired some new gear by selling some old gear and it has worked out quite nice. We took our honeymoon last June to Pictured Rocks National Lakeshore hiking all 42 miles and it was a blast. At first, we didn't buy much new gear but since we both enjoy it so much we have invested in some key pieces this winter that will lighten our load for sure. I got rid of my older Kelty Super Tioga and and am in current search for a new bag. We both replaced our 4 pound sleeping bags with new ones, those 2 pound self inflating army surplus sleeping mats were replaced as well! And a new tent acquired here on BPL! (thank you!)
This current gear list is set up for a solo hike with what we have. Obviously, if the two of us were hiking there is shared weight like the tent and such but this would be set up for multi-day backpacking solo.
Any recommendation of losing some weight is greatly appreciated.
So here it is!
Pack:
Kelty Lakota 65
56oz or 3 pounds 8oz
This is my wife's pack:

Sleep system:
REI Flash Sleeping Bag (Men's Long) w/ stuff sack 1 pound 12.6oz
REI Flash Sleeping Pad (long) w/ stuff sack 1 pound 1.5 oz
Therm-A-Rest Stuffable Pillow 1oz
47.1oz or 2.9 pounds

Next is the cooking system:
Vargo Titanium Pot with bag and lid 5.3oz
Whisperlite Universal with windshield and repair kit 14.4oz
Flint and Steel 1oz
Plastic Spoon and Fork 1.1oz
Lighter .5oz
Fuel Canister (Full) 6.7oz
29oz or 1.8 pounds
Here I haven't yet decided if I need the top and the bag for the pot. It nests nicely with my Nalgene. Lighter is redundant but than again it only weights .5 oz. I also have not decided if I need the windshield and all out on a trip, probably not…

Water Storage and Filtration:
Katedyn Hiker Pro (with all the tubes, sponge, cleaning kit, and nalgene adapter cap) 14.1oz
Nalgene cantene 3oz
Nalgene 1L 6.3oz
Aqua Tablets 2.2oz
25.9 oz or 1.6 pounds
I'm thinking I need a water bladder. I have one, but its old and am going to replace it soon so I didn't list it here.

Shelter:
Shangri-La 3 Fly 1 pound 8.4oz
Shangri-La 3 Nest 2 pounds
6 MSR groundhog stakes 3.5 oz
MYOG coupler 1.3oz
61.2oz or 3.8 pounds
Here I've replaced the main pole with my own way of coupling two hiking poles together. These hiking poles are real old. Anyone remember Galyan's?! yup! going on 11 years old!

Hygiene and First Aid:
I can probably slim this down but it is a very capable first aid kit (includes patches for goretex and sleeping pad)
First aid kit 11.6oz
Trowel 2.1oz
Pack Towel 1oz
14.7oz or .9 pounds

Lighting/fire/tools
Fenix E11 flashlight 1.9oz
Leatherman Juice 4.5oz
Firemaking kit 3.7oz
10.1oz or .6 pounds
The multitool is heavy but capable as well. I haven't figured out the fire making stuff yet. It doesn't make sense to me b/c I have no other fire preparation tools listed. I would have to bring my folding saw and survival knife. I might just leave that out. I could potentially lose a half pound tripping the fire kit and Leatherman.
Fire kit contains trioxine, some fat wood, small container of vaseline and cotton balls.

Rain Gear/insulation:
Patagonia Rain Jacket 13.4oz
Columbia Rain Pants 12oz
Gregory Rain Cover (not pictured) 4.7oz
Patagonia nano puff (not pictured) 11oz
41.1oz or 2.6 pounds
I was actually surprised on how much these weigh. I just bought the jacket so it won't be replaced for sometime. My wife has a set of Froggtogg rain gear I always make fun of until i saw the weight…

Clothes:
Orange Athletic Shirt: 5.2oz
White Athletic Shirt: 5.4 oz
Socks x2 (Cabela's and Smartwool) 7oz
North Face button up 9.3oz
Galyans convertible pants 12.4oz
Shemagh (not pictured) 5.5oz
OR Hat (not pictured) 1.7oz
Underwear x2 (wicking underarmor) 6.2oz
52.7oz or 3.3 pounds

Total is:
337.8oz or 21 pounds
