Bushwalkers tend to use gaiters more as they go on more trips. Gaiters are generally not needed on easy to moderate walks. On harder walks, in wetter and muddier conditions and particularly off-track walks, gaiters are very desirable.
The advantages of gaiters are:
- Footwear, socks, trouser and leg are protected from scrub, sticks, dirt, pebbles, mud and other debris.
- Prevents debris getting into footwear.
- Easy to clean and remove biological material.
- Provides some resistance to snake bites (see below), leeches and ticks.
- Can be used in tent vestibules to cover dirt or mud.
Some disadvantages of gaiters include:
- Some gaiters are not very breathable; sweat accumulates.
- Can hide leeches and ticks. User must be careful to check underneath gaiters for hitch-hikers at breaks.
- More time needed to change footwear for river crossings.
- More time needed to get ready in the morning or after lunch breaks if gaiters are taken off, which is a good idea because sweat accumulates.
Bushwalking gaiters do not protect against snake bites. While thicker knee-length gaiters afford better protection than any other option, they do not guarantee non-penetration by a snake, and snake bites should still be treated even if there is no visible wound. Also, given the tendency for gaiters to collect mud, seeds and spores, users must take biosecurity issues seriously and properly clean gaiters after every trip.
