    Polish GOOSE DOWN with … the BEST Japanese PERTEX fabric
    The Criterion Prime 400 Down Sleeping Bag can be used for a diverse range of activities including 3 season trekking, summer Alpinsim and microadventures.
    The night time temperature when you are doing these activities could well be a few degrees below freezing.
    With a comfort temperature of -7°C the Criterion Prime 400 will keep you warm during most of the year in the UK.
    The weight of 905 grams enables the sleeping bag to be carried comfortably in your rucksack, bike cylcle panniers etc.
    Made using a Pertex Quantum 52g/m² ripstop shell filled with 700g of 870 FP Diamond Grade White Polish Goose down.
    Trapeziod construction eliminates cold spots enabling a comfortable night’s sleep.
    A DWR+ treatment of the shell helps protect the down from any dampness that may occur in your tent, from condensation or wet gear.
    Criterion sleeping bags contain only Polish goose down, whose source is the non-polluted region of forests, lakes and beautiful, natural
    landscapes of North Eastern Poland.
    This is a particularly cold part of Poland, suffering long winter weeks of arctic air with temperatures once reaching as low as -36°C  
    It is to combat such severe conditions that the geese, whose natural habitat has been this region for thousands of years, have evolved their protective down to a quality which is unmatched anywhere, both for heat retention and for durability.

    Supplied with compact, fully-featured stuff sack and breathable, mesh storage bag
    The Criterion stuff sack is specially designed for easy, one handed stuffing.
    When not in use Down sleeping bags should NOT be left in their stuff sacks under compression. That will reduce their lofting ability.
    For storage, therefore, they are supplied with a Criterion storage bag
    Trapezoid Baffles are the ideal mix of the best qualities of Boxwall and V Baffles.
     - Less heat is lost through stitching than in sitched baffles
    Boxwall Baffles are the simplest answer to some of the disadvantages of stitched through baffles.
    The creation of side walls serves two purposes.
    - Firstly the down contained within the baffle is able to loft fully and insulate better, as the ends of the baffle are not being pushed together by stitching.
    - Secondly there is no stitching that goes directly from the inner to the outer shell, this markedly reduces body heat lost.
    Differential Cut, this is a manufacturing technique by which the outer surface of the top side of the sleeping bag is wider than lower (inside) surface.
    This helps the down to expand outwards from the centrally located body position thus facilitating optimum lofting

    Criterion Range Temperature Ratings
    All of the Criterion models in the table below have been independently tested for warmth by Leeds University Performance Clothing Research Group
    The results for all of the Criterion models were at least as good as stated – and were better in most cases
    To get to their stated temperature ratings the sleeping bags have been tested, to British Standard BS 4745 and ISO 5087-1, by the University of Leeds’ Performance Clothing Research Group.
    These tests gave both a TOG rating which you would be familiar with when buying a bed duvet as well as a specific temp in °C.  
    This is a starting point as laboratory tests are controlled environments, the mannequins do not move or sweat. 
    Through product testing, expeditions and tester feedback Criterion have refined the labratory ratings to the ones advertised for the sleeping bags.
    In cases where they have changed the tested rating  the temperature has been reduced to be more cautionary and safer.
