Royal Thai Army when on guard duty, a similar helmet but with plumes is used when in the full dress uniform with the plumes in uniform facings (similar to the bearskin). White Wolseley helmets are worn by mounted Presidential Guard members in Harare, Zimbabwe, during the State Opening of the first session of Parliament each year. Civilian and commercial uses The pith helmet has had a limited comeback in recent years, with their now novel appearance and genuine functionality making the headdress increasingly popular for gardening, hiking, safari and other outdoor activities. Today's helmets are generally available in four basic types (see below). These have changed little since the early 1900s, except that for easier adjustment the inner headband utilises hook-and-loop fasteners (e.g., Velcro) instead of the earlier brass pins. They can also be soaked in water to keep the wearer's head cool in hot weather and feature an adjustable chinstrap towards the front. (i) French pith helmet. This is the most functional of the helmets, with its wide brim providing more sun protection than the more narrow-brimmed variations. This helmet is mostly made in Vietnam, where the design was inherited from French colonial patterns. (ii) Indian pith helmet. The Indian model is almost exactly the same as the French one, but with a slightly narrower brim and a squarer dome. It shares with other helmets the ventilation "button" atop the dome. (iii) African pith helmet, or safari helmet, is a variation mainly used in savanna or jungle regions of Africa. It is generally a khaki-grey colour, with the same dimensions and shape as the Indian helmet described above. (iv) Wolseley pith helmet. This variation of the helmet was named after (but not designed by) Field Marshal The 1st Viscount Wolseley, an Anglo-Irish military commander, and widely used by the British Army and Colonial civil service from 1900.
