You might have trekked the mountain paths or the thick forests. You might have had to scramble up the rocky mountains. Or may be crossed a fast running stream. At the end of the day, you are dead tired. All you are thinking of now is the cozy warm comforts of your sleeping bag. And you know that you have to get up early the next day for yet another arduous trek ahead no less exciting. The sleeping bag simply becomes your heavenly bliss.
But does the sleeping bag that you have with you give you all that you desire? Of course, a synthetic fill bag is much cheaper than a down fill bag. It is easier to clean a synthetic bag. But it is the insulation that is critical where you are now. It is the ground on which you decide to lay down to sleep decides how much insulation you need. If it is a wooden floor, it is warmer than a cement floor which is cold. A hut or an open space brings in all the chill wind rather than a protected camping tent.
The synthetic bag offers good insulation. The insulation also lasts longer. The down bags offer more warmth than the synthetic fill ones and are best suited for winter. These are also lighter. The down bags are good for taking along on a long expedition. But if the weather is wet, the down fill bags lose their insulation. You must take good care of the down filled bags so that they are not damaged even though they are more durable and long lasting. The synthetic bags are less expensive.
The rectangular sleeping bag is more spacious than the mummy shaped bag. But the insulation of the mummy bags is better than the rectangle bags. While the mummy shaped bags are rolled, tied and packed into a sack, the rectangular bags can be folded and secured using straps or chords. The helium marmot bag is ideal for long treks, particularly up into the mountains.
Choose your sleeping bag keeping the weather, the environment and the duration of your travel. Check whether it is dry or wet climate. You will not regret this.
