The significant difference between both styles is the cut and also form of the bags. The mummy bag is extra restricting. You can think about it like your own individual cocoon where you can go to bed in the evening as a caterpillar as well as wake up the next early morning as a butterfly. You're completed tight with not a lot of area to relocate. The rectangle-shaped bed on the other hand gets its name from its rectangle-shaped form as well as lets you relocate your legs.
Rectangular sleeping bags are the initial and also most typical form you'll see on the market. I directly don't think there is much of a visible difference in between the fillings nonetheless synthetic fibers will certainly not soak up water and will certainly keep you warmer also if the bag is a little bit wet. A damp down resting bag is very hard to dry out as well as is taken into consideration even worse than having no sleeping bag at all.
Tapered resting bags grow narrower towards the feet, providing you with a close fit. The closeness of these bags produce more warmth inside whilst resting, nevertheless, the lack of free space limits motion and also might not suit many individuals. They are additionally smaller sized compared to rectangular ones as well as can be rolled up extra compactly, making them much easier to bring whilst on treking journeys.
