Dumlup-Lubra is a ceremonial as well as a functional helmet jointed to the Adi tribe of Arunachal Pradesh and displays its fine craft as well as the warrior tradition of that tribe. The oval-shaped helmet is made up of split, thick cane strips which are finely arranged to give both strength and beauty.
The exterior of the helmet is embellished with thick cane strips arranged decoratively. Among these strips, five thick canes extend toward the rim, forming the stands of the helmet. The entire helmet was lacquered black for a fine finish and protection. The front of the helmet has been adorned with two boar tusks, while the silhouette carries a hornbill's beak: a reflection of the tribal reverence of nature and all its creations. The beak has been ornamented with dried bird hair and skin, emphasizing the intricacy as well as the symbolical nature of the design of this helmet. Worn especially for ceremonies, it also served the purpose of protection and was a symbol of pride and status of an esteemed warrior in the tribe.

An inner surface of a bark strap is presumably tied to ensure firmer wearing during the rituals or processions. The outer surface is completed with more cane stems as shown in its structure and design. However the really different aspect of this helmet is its decoration: a layer of animal fur and a prominent animal tusk adorning the front. This denotes power and protection as well as tribal symbolism. The rim is reinforced at the top by a thick cane stem and it adds more to the durability and finish of the helmet. Putting these things together—cane, bark, fur, and tusk—shows how deeply into nature, the Adi tribe has been rooted and it also indicates how much they have relied on the forest for available resources.
