The Mythic is one of the lightest and most packable sleeping bags available at this point in time. The combination of the ultra high quality 900 fill power down and lightweight 7 denier outer provide a sleeping bag which will pack down to almost nothing while being able to accompany you down to -1°C. 

The most important aspect of the Mythic is the exceptionally high quality insulation. The 900 fill-power down is a jump up from Rab's previously used insulation and even that of other brands. The quality of this insulation means the Mythic will pack up far smaller than most sleeping bags, is far lighter and requires less insulation to equal the same warmth as cheaper alternatives. This is then treated with a nikwax coating to allow the down to soak up less water and stay warmer if the bag does happen to get wet (although we would strongly recommend always keeping a down bag dry). As if the quality wasn't enough to persuade you, the down is all R.D.S certified, meaning it comes from birds which have not been live plucked and have lived a free-range existence. Not only is the down ethicly sourced and of the highest quality, but Rab also incorporate clever baffle techniques to optimse warmth and pack size. Trapezoid baffles feature throughout the bag as they leave less cold spots and will pack smaller than standard rectangular baffles. 

Further optimising the Mythic's high warmth-to-weight ratio is the super light outer fabric. Pertex Quantum 7 denier is used throughout the entire bag, providing a highly stitched surface which stops down escaping but still optimises pack size and breathability. It's perfect for mountain activities due to it's high durability but low weight and small pack size. 

An angled footbox allows you to sleep on your back with your feet pointed upwards without discomfort, while a glow in the dark zip puller makes it easier for those early morning excursions or late night trips out. A cotton storage sack is included to safely store the bag when not in use, and a drybag compression stuff sack is provided to pack the Mythic down as small as possible when out in the mountains. 

The Mythic is just a brilliant mountain orientated sleeping bag. It's exceptionally lightweight, packable, warm and features some of the best sleeping bag knowledge in the world. After all, Rab's first product was a sleeping bag.

The product I bought was competitively priced. The video demonstration of the product assisted me in my decision to purchase the item and was very informative, as it showed all of the features and the fit. I chose "click and collect" which was an efficient and quick process. I would definitely shop here again.
