Aleaxander: Here's what I posted on youtube. Most of which is redundant to BPL members who have already drunk the UL Kool-aid:
Great video and nice introduction to UL backpacking and how it doesn't have to be expensive. I'm sure you have no end of tweaks and adjustments you could do but here are few small ones that come to mind: wrap 18 inches each of duct tape, leukotape and electrical tape around your water bottle(s) – it keeps it convenient and slightly reinforces the water bottles and makes them less slippery. I'm a Swiss Army Classic guy (21 grams, $5 on eBay for TSA-seized ones) which is both cheaper and lighter than your Buck knife and gives you scissors, nail file and tweezers. That's a lot of Vaseline – I'd repackage some into a repurposed hotel shampoo container or better yet, a professional-sample size of antibiotic ointment (mostly helpful for keeping a cut moisturized as it heals). I've had bad luck with vinyl ponchos in thunderstorms if the temperature drops – they get very brittle. Probably fine in the SE in the Summer. At higher elevations, I'd instead bring a second Hefty trash bag as a cheap poncho.
I assume the lightweight sleeping bag is in conjunction with wearing your clothes inside the bag on a colder night. Just like some people aren't ready to go to a tarp (and you've given them full bug and rain protection with that tent), it takes people a while to get their head around a quilt instead of a sleeping bag. Thrift stores have bed-sized polyester quilts that can be cut down into 2 solo quilts. $10-15 plus needle&thread (or red-neck DIY it with duct tape) for two quilts! saving you weight and volume and cost.
What I like most about your selection of really cheap but functional items is that it gets people started on the right path (light, simple) and then, if they really like it, they can upgrade one item at a time (probably first going to a 1 to 1.5-pound UL pack or maybe transitioning from tent to tarp) because having only $20-40 in each item, they wouldn't be so invested in the original gear. I see a lot of people hesitate to change from the traditional bag or tent or tent that they sunk $200-300 into when they realized there are far lighter options.
