The Mythic 200 is a super-lightweight sleeping bag filled with high quality Rab Fluorocarbon free Hydrophobic, 900 fill European goose down and uses very light Pertex Quantum GL fabrics.

The Mythics are now the best performing range of sleeping bags that Rab produce in terms of warmth-to-weight.

The trapezoidal chevron baffle system is used to provide very efficient warmth and the best possible use for the 900 fill hydrophobic goose down that is used. The superlight Pertex Quantum GL fabric allows the down to hug the body providing maximum levels of warmth and minimum ‘dead-space’ in the bag.

The Mythic 200 is an ideal companion for anyone who wants maximum warmth for minimum weight whether for lightweight backpacking and adventure racing mountain marathons.

Rab says:

The pinnacle of innovation, the Mythic 200 Sleeping bag is an ultra lightweight down sleeping bag with the best warmth to weight ratio in the Rab range. Designed for mountain activists looking to reduce weight while moving through the mountains, for use in warmer conditions where weight and packsize are crucial to success, such as long multi day routes or summer trekking.

Since our beginnings when Rab Carrington hand stitched the first sleeping bag to bear his name, Rab design has drawn on experience from years spent in the mountains. The Mythic Sleeping Bag continues that tradition, once again pushing the boundaries in innovation and design.

Weighing in at just 475g the Mythic contains 200g of the highest fill power ethically sourced European Goose Down. Achieving an exceptional warmth to weight ratio, this bag retains all the features you need to stay warm and protected in a mountain environment. The tapered mummy shape with angled foot box gives a generous fit for the weight. Weight saving baffle construction prevents down shift, while the chambers are angled downwards in chevrons keeping the down over the centre of the body to ensure core warmth throughout the night. Each bag is hand filled in Derbyshire using Hydrophobic down developed in conjunction with Nikwax®.

The internal collar is ergonomically designed, and collar, hood, and internal baffles have drawcords which can be cinched in for extra warmth. Designed with a quarter length YKK main zip with glow in the dark puller, while the bonded zip guard works as a draught excluder.

Super lightweight trims and features reduce weight, and the dry bag compression stuffsack provides protection from the elements and a smaller packsize while on the move.

Every element of the Mythic 200 is designed to deliver optimum warmth for minimum weight, allowing you to withstand the challenges of moving fast and light in alpine environments.

I've used the Rab's Mythic for quite a few nights and it definitely lives up to its rating, I tend to sleep cold but had no problems keeping warm without any other clothing, on a decent sleeping mat.

Reducing the weight of the sleeping bag ‘shell’ is exactly what RAB have done with the Mythic sleeping bag range, and they’ve managed to do it with very little compromise on features. I’m very glad they didn’t give in to the temptation of a ‘sewn through’ construction which can cause cold spots.

The zip is interesting – it comes apart at the bottom, I’m pretty sure this is aimed at multi-day climbers but I undid the zip to attend to a call of nature and the parts separated at the bottom, it was a frustrating struggle to get them together and zipped up again.

I liked the cordlocks on the hood and shoulder baffle, these are easy to use, there is an anti-snag baffle along the main zip which worked about as well as on other bags. Space-wise I found it perfectly adequate. There aren’t many bags around achieving such good results at such low weight, and some that do compromise more on features than the Mythic bags.
