The choice primarily is a query of insulation varieties. Two classes prevail: artificial and down. Artificial baggage, just like the NEMO Forte, are bulkier and total heavier when in comparison with a down-filled bag on the identical temperature score. In addition they are usually cheaper and keep heat when moist (not like down).
Down-filled baggage, just like the Western Mountaineering Alpinlite, are inclined to price extra and be extra delicate to abrasion and tearing as feathers can leak out, diminishing insulation. The benefit of down-filled baggage is that they pack extraordinarily small and might present extra heat with much less materials and due to this fact, much less weight.
