Wm is the best - Western Mountaineering Mitylite 40 Sleeping Bag 850 Down

I've owned the Terralite for 2 years and still, somehow, manage to feel a sense of primoridal joy every time I climb into it. It's temperature rating is true; I stay comfy at 25 degrees while the wind howls outside my mountain tent. Believe this: The Terralite is warmer than my 0-degree rate NF bag!! (The double exclamation point is intended.) I've purchased the Mitylite for summer use in the Canadian Boundary Waters, where the temperature occasionally strays to around freezing but is usually in the 50s at night. I have not yet slept in the Mitylight, but I've inspected it closely and like what I see. Gosh, it folds up small and light! Thank you, Western Mountaineering.
