Marmot, a company well known for their quality mountaineering products, has announced the launch of two new sleeping bags. And they claim that they're 'simply the most technologically advanced bags on the market'.
The two new sleeping bags, the Plasma 15 and the Plasma 30, are being launched this Spring and Marmot claim they'll offer the best warmth to weight ratio as well as be the 'lightest most functional bags possible'. However, this comes at a price. Retailing at £360 and £400 they might be out of the average adventurers budget.
So, what makes these new bags so remarkable? Well, firstly they have the largest fill power available, with a 900 down fill, meaning the bags will be able to offer warmth at a reduced weight. The down can also be moved around the bag by the user thanks to the 'flow gate construction', a unique idea that will allow you to push more insulation to particularly cold areas of the body. It'll be interesting to see how this works as manufacturers usually try to minimise the movement of insulation to avoid cold spots.
The bag has been manufactured using Pertex's Quantum fabric (the same fabric used by Rab's much loved Infinity down jacket), which means the bags will be strong, lightweight and packable.
The plasma 30, which has a comfort rating of 5.8ºC and an extreme of -14.4ºC, weighs in at just 694g (for the large size), and the Plasma 15, with a comfort rating of -1.7ºC and an extreme of -25.9ºC, weighs 919g (again for the large size).
Samples aren't available for these bags yet, but when they are we'll be trying to get our hands on them and report back
