Designed with a generous “expedition fit,” they accommodate layered down clothing for high-altitude bivouacs and extended time in extreme conditions, with sizes available in Small\/Medium and Medium\/Large.\u003c\/p\u003e\n\u003cp\u003eRated to an uncompromising -40°C, these bags are crafted to deliver life-preserving warmth when conditions turn truly hostile. Every detail is optimised for performance in severe cold: Hydronaute XT laminated membrane fabric shields against spindrift and external moisture while efficiently venting internal vapour; vertical chest baffles stabilise insulation to eliminate cold spots; and a close-fitting, down-filled hood with Hydronaute XT lining guards your head and keeps critical insulation dry.\u003c\/p\u003e\n\u003cp\u003eA spacious foot-\u003cmeta charset=\"utf-8\"\u003ebox design with Hydronaute XT lining ensures your down stays protected from snow-covered socks or booties, while Mont’s innovative Cordless Collar System wraps the shoulders in exceptional warmth without the discomfort of traditional drawcords. Interlocking down-filled draught tubes run the length of the zip, sealing out the cold and locking in heat when the temperature plummets.\u003c\/p\u003e\n\u003cp\u003eWhen you’re pushing toward the summit or riding out a storm at altitude, the Expedition 8000 XT is built to keep you warm, dry and alive.\u003c\/p\u003e\n\u003cp\u003eComfort Temperature Rating for warm sleepers: -40°C, \u003cmeta charset=\"utf-8\"\u003ecold sleepers: -30°C.

Guaranteed to maintain greater warmth \u0026amp; comfort than coated fabrics, Hydronaute XT is the best protection for down sleeping bags \u0026amp; clothing in cold to extreme conditions. Waterproof to 20,000mm, highly breathable 48,000g\/m2\/24hrs: If not removed promptly, water vapour from your body will gather on the down \u0026amp; reduce its ability to trap warmth. Hydronaute XT fabric expels 20L of water vapour per square metre per 24 hours for drier down, greater loft \u0026amp; maximum warmth. Warmth Sealed In: With a 100% windproof rating, even Arctic blasts will not penetrate Hydronaute XT fabric, keeping warm air trapped inside.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRADIAL ARC BAFFLE\u003c\/strong\u003e: The Radial Arc Baffle System is a significant design innovation that improves the thermal efficiency of a Mont sleeping bag. Radial Arc baffles curve naturally around your body rather than compressing the down around your body.\u003cbr\u003eWhen a down baffle (chamber) is bent, ripples in the fabric occur, which will create cold spots and compress down. The radial Arc Baffle System reduces distortion and increases warmth and loft\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCORDLESS COLLAR SYSTEM\u003c\/strong\u003e: A cordless Collar System provides superior insulation around your shoulders and neck without the need for uncomfortable and fiddly draw cords. The Cordless Collar can be wrapped snugly around your neck and shoulders, or in warmer conditions, can be secured inside the sleeping bag to increase ventilation. The Cordless Collar is a unique Mont design and can be found on Brindabella, Spindrift and Expedition 8000 sleeping bags.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTUCK STITCHING\u003c\/strong\u003e: Tuck stitching is a construction method that conceals the stitch inside the sleeping bag, thereby protecting it from abrasion and snagging. This is in comparison to top-stitched seams, where each stitch is exposed, which is commonly found in other sleeping bag brands. Tuck-stitched seams are also more water-resistant than top-stitched seams, again because the seam is concealed internally. Tuck stitching attaches the lock-knit baffle to a small fold in the shell material.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTOASTER POCKET\u003c\/strong\u003e: is for slow-release, air-activated heat packs: your toes and feet will never be cold again. \u003c\/p\u003e\n\u003cp\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/BDQupEnAxN4?si=E1LQH3twqgIs-qDL\" height=\"315\" width=\"560\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMore Help?\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eFor further assistance on choosing your down sleeping bag, we have an article explaining fill power, the pros and cons of down over synthetic insulation and more info on caring for your bag available to view \u003cspan\u003ehere: \u003c\/span\u003e\u003ca title=\"Article: A guide to down sleeping bags...down explained\" href=\"https:\/\/rockrun.com\/blogs\/the-flash-rock-run-blog\/a-guide-to-down-sleeping-bags-buying-guide\"\u003eA Guide to Down Sleeping Bags\u003c\/a\u003e\u003cspan\u003e.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDown distribution: 55% canopy 45% base\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eLarge boxfoot section accommodates the wearing of inner boots or down booties\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eCross block baffles on torso prevent down shift between canopy \u0026amp; base\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eRadial Arc Baffle System on horizontal baffles maximises baffle loft height \u0026amp; warmth\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eDifferential cut reduces compression \u0026amp; cold spots\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eBox walled chambers for warmth\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eTwin interlocking down-filled draught tubes along zip retain heat\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eDurable laminated Nylon anti-snag shield along zip\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eContoured hood with down-filled muff\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eUnique Cordless Collar System wraps efficiently around shoulders without the need for fiddly and uncomfortable drawcords\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eDrawcords across chest and at top of hood\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eRecessed drawcords provide comfortable, warmth retaining closures\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eTuck stitched seams: a construction method that conceals the stitch inside the sleeping bag thereby protecting it from abrasion and snagging.
