OTHER FEATURES
Neck baffles reduce the effect of convection drastically,
stopping warm air escaping when shifting in the bag. The complexity
and weight of the baffles depends on the intended use and temperature
range of the bag. Some ultra light bags don't feature a neck baffle
and depend instead on just the draw cord around the face.
Zips add weight to the bag, both due to their own weight and the
weight of the baffling and anti snag tape, seams etc. By losing
the zip, or reducing its length you can save a great deal of weight.
The drawbacks are the bag is harder to vent, but this isn't a problem
on 'summer' weight bags.
