£440.00 £495.00

The Criterion Prime 700 is a 4 to 5 season Down Sleeping Bag is designed for winter trekking and winter Alpinism.

    The BEST Polish GOOSE DOWN with … the BEST Japanese PERTEX fabric
    The Criterion Prime 700 is a 4 to 5 season Down Sleeping Bag is designed for winter trekking and winter Alpinism.
    With a comfort temperature rating of -18°C you can camp out all year and also in alpine conditions.
    Its weight is 1210 grams, which is low considering the low comfort temperature.
    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.
    Colour: Graphite outer / Red inner 
    Construction: Trapezoid top, Boxwall base
    Fabric: Pertex Quantum Ripstop, 52g/m², Made in Japan by Mitsui Bussan Textile Co.

    Collected in accordance with Downpass ethical standards
    Fill weight: 700g
    Fill power: 850 
    Comfort temperature rating: -18°C, 
    Criterion offer a single comfort temperature, which is the temperature limit at which they feel will allow the most comfortable night’s sleep.
    Average weight of sleeping bag: 1210g
    Stuff sack size: 17 x 17 x 36cm, weight 23g
    Maximum width: 80cm shoulders, 52cm foot
    Maximum user height: 190cm, 6´3"
    Differential fill and differential cut, 60% fill in the top / 40% in the base
    Box foot - comfortable, trapezium shape, for all feet positions , 
    Cowl hood with one hand operated drawcordInsulated neck baffle with velcro fastener and elasticated, one hand operated drawcord
    Full length, two-way YKK zip plus velcro fastener
    Anti-snag, full length zip baffle, down-filled to prevent cold spots
    Inside pocket and hanging loops
    Supplied with compact, fully-featured stuff sack and breathable, mesh storage bag
    The Criterion stuff sack is specially designed for easy, one handed stuffing.
    It has just the right diameter to enable the sleeping bag to be inserted one handed without it being able to “escape”.
    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 Boxwall and
    Stitched Through Baffles, shell stitching is not directly opposite inner bag stitching. Angled side walls contain the down and reduces
    migration within the baffle reducing cold spots. There are less baffles than in a V shaped design, this means less weight, but at the cost
    of some thermal efficiency. Body heat is trapped within the baffle keeping the temperature stable and comfortable.
    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
    Separate Zip Baffle and Neck Collar
    Used in Criterion 3 to 4 season Prime sleeping bags. The separate zip and neck collar system, offers a full-length zip baffle, with a fully independent and adjustable down-filled upper and lower neck collar with Velcro fastening and differential fill. The zip baffle and collar fill power is 870
    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
