GSI Outdoor Backpacker Mug
Bought this based on excellent reviews and. they were spot on. Light, easy to clean, distinctive. On review suggested the polypropylene mug might fall out of the insulated neoprene sleeve. Didn't have that problem, but wrapped two rubber bands inside it to make it more secure.
