Was looking for a sub 1kg bag for backpacking but the budget didn't stretch too far. The Thylacine specs appeared to offer a quality bag withtop end features. It's roomy as a semi-rec, but can be tightened to mummy-like dimensions to increase it's warmth. Have had it down to 2degC with only a merino layer longjohn and socks underneath and was comfy. Can recommend.
