Being new to the UL behavior pattern, I recently bought a digital scale, and have been amazed as I go thru gear and weigh and note the weights of so much "not light" gear.
I just weighed an insulated plastic mug, one that was given to me by the Serta Bed company, and I was amazed to see it weighed 4.4 oz, and it was just under 400ml.... Well, that $30 Ti mug weighed 4.2 oz... so I was like, damn, saving money and liking the mug all at once!
I love my tea in the evening as well. I am looking forward to "discovering" new light stuff that is already there!
