The Rab Infinity 500 is a light down sleeping bag stuffed with the highest quality 850 fill European goose down. It is ideally suited to winter Alpine use, British winter mountaineering or any other situation where high levels of warmth must be combined with good packability and low weight.

The Infinity series feature Petex Quantum GL outers; which offer the best weight to durability ratio of any Pertex fabric available. Combine this with 500g of 850 fill, high spec goose down and you've got one of the very best bags in terms of warmth to weight ratio.

Rab have fitted the Infinity with a trapezoidal vertical baffle system with 'Flowgate technology', which has been uniquely customised to provide supremely efficient warmth by keeping the down equally distributed throughout the bag. The proportionally assigned differential cut means the down can loft to its full potential quickly and visibly 'rises' when you take it out of its stuff sac. The super light Pertex Quantum GL fabric also allows the down to hug the body, providing minimum 'dead-space' and thus keeping you warmer.
