If you're going where the mercury in your thermometer will freeze, you'll be wanting more than your average sleeping bag. Rated for a good night's sleep at minus 50 degrees centigrade (even Polar Bears catch a cold at those sort of temps) the Redline Regular Down Sleeping Bag is Mountain Equipment's ultimate warm place to get some shut-eye.
Specified for the extremes of polar exploration and winter or high altitude mountaineering they've thrown every bit of high tech, high spec product, and design into it. From the whopping 1350 grams of ultra fluffy 850, Fill Power Codex certified down fill, to the complex combination of trapezoid and V-shaped baffling that keep the down locked in the optimum locations to keep you warm. Encapsulated in the game changer fabric Drilite Loft with its 1500 HH water repellent outer you can be confident the down won't be spoilt by melting snow or condensation overnight.
Besides the clever baffles, there's also EXL and ground level seams. The EXL is an elasticated inner layer that keeps the bag closer to your body, increasing thermal efficiency by a couple of degrees with no extra weight. The ground level seams rather than conventional side seams make the top layer extend down the sides to avoid cold arm syndrome.
EN ratings that define temperature specifications can't handle the Redline, it's just too warm! So Mountain Equipment state the average bloke with base layer clothing and a liner will be toasty even at minus 50. Be careful, if you're this warm you might find a Yeti snuggled up next to you in the morning.
The expedition fit is a tapered shape with additional room around your upper body to accommodate extra clothing and kit you don't want to freeze solid overnight. The foot of the bag has a 'shark fin' shape that's ergonomically designed to fit around your feet in their most relaxed and natural position.
Your feet are warm, but what about your head? No less than 8 baffles control the down around here. Also, the Gemini collar with down draft tubes keeps shoulders and neck warm and prevents warm air being forced out past your face if you move around in your sleep.
