Full Mental LOKI Jacket

I tested my Loki Levity Jacket's carrying capacity on this climb. I had NO PACK, only my jackets convertible lumbar / daypack "N-Pac" design. Without a separate pack I was able to carry; 2 liters of water 1 micro fleece top 1 loki softshell pant 4 energy bars, 1 camera 1 multi tool 1 small roll duct tape 1 tincture tea tree antisceptic 1 bottle sunscreen I saved the weight of a day pack on the backpack in. The N-PAC worked great on this climb. Do more with less. Is that why its called a "lesson"?
