I am pretty much done with tinkering around with my spring/fall base weight gear lists and I am very happy with them. For rain or high chance of rain, my base is just under 8lbs, and for dry weather it is closer to 7lbs. My summer base is sub 5lbs I am also happy to report.
I had to cancel a trip I was going to take this coming weekend due to illness, so I figured what the hello, might as well do something I have been putting off for some time now.
Please note that the below list is for the coldest temps in early spring and late fall, around freezing to -2C (28F) or so. I can obviously ditch a layer if it is warmer, but figured I'd do the heaviest possible combination of clothing. Also note that a rain poncho is accounted for in my base weight (see my profile to check that out), as is a synthetic vest (in case it is extra cold at night), sleep socks, and a synthetic beanie. Final note, for deep off-trail/bushwacking adventures I will switch out the shoes for boots, weight be damned. I'd say it's about 50/50 usage of the New Balance vs. US army issue boots. Insanity, I know.
On to the list:
Underwear – 92g
Wool socks – 88g
Synth base layer bottom – 165g
" " top – 255g
Synth hiking pants – 365g
Synth sweater – 266g
Synth soft shell jacket – 460g
Hard shell jacket w/hood – 560g
Baseball cap – 77g
Wool buff – 55g
Leather gloves – 105g
Synth glove liners – 35g
Shoes (New Balance) – 714g
Total = 3237g (7.12lbs)
Which means I am wearing less than what I am carrying, even when it is really cold. I'm pleasantly surprised, actually, I was expecting it to be more, I think because the first time I weighed my base weight gear it was like 22lbs. But then again, I am not really sure what a "light" 3 season clothing worn list looks like, because I haven't really bothered with looking into it that much. I have focused the bulk of my attention getting from 22lbs base to around 7-8lbs base and still be just has comfortable and safe, which was no small task!
Any tips, suggestions, questions, and feedback are welcome. I am pretty broke at the moment, so free/cheap fixes are the most welcome, as you can probably tell by the complete lack of down clothing I own.
