Rab Mythic 600 Left Zip Description

  • Brand : Rab
  • Season : Not Applicable
  • Code : RAB MY600LZ
  • Packaged Weight : 1.6KG
  • The pinnacle of innovation, and designed for mountain activists looking to reduce weight, for use in very cold conditions where weight and packsize are crucial to success, such as long multi day routes involving winter bivouacs, the Mythic 600 Sleeping bag is an ultra lightweight down sleeping bag with the best warmth to weight ratio in the Rab range.  
    Weighing in at just 885g the Mythic contains 600g 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 600 is designed to deliver optimum warmth for minimum weight, allowing you to withstand the challenges of moving fast and light in alpine environments.

    EN Sleeping Bag Temperature Ratings
    EN23537 is the European standard for sleeping bags and requires a thermal manikin test which produces four temperature results — upper limit, comfort, lower limit and extreme. There is no legal obligation to use this standard though most reputable brands do, even non-European ones. There is an exemption for military sleeping bags and sleeping bags for extreme temperatures, ie a comfort range of below -25°C. 
    Upper Limit: the temperature at which a standard man can sleep without excessive perspiration. It is established with the hood and zips open and with arms outside the bag.
    Comfort: the temperature at which a standard woman can expect to sleep comfortably in a relaxed position.
    Lower Limit: the temperature at which a standard man can sleep for eight hours in a curled position without waking.
    Extreme: the minimum temperature at which a standard woman can remain for six hours without risk of death from hypothermia (though frostbite is still possible).
    For the purpose of these measurements, a "standard man" is assumed to be 25 years old, with a height of 1.73m (ie 5' 7", not very tall) and a weight of 73kg; a "standard woman" is assumed to be 25 years old, with a height of 1.60m (ie 5' 2.5") and a weight of 60kg.
    Rab Sleep Limit: This is Rab's recommended lowest temperture for a comfortable night's sleep.
