The triangular bandage has been a first aid staple for over a century because it genuinely does more than any other single item in the kit. Arm sling, broad arm sling, improvised tourniquet, dressing holder, splint securing, limb immobilisation, head bandage — the same piece of fabric does all of it, depending on how it is folded and applied. If there is one item that earns its place in every kit regardless of size or application, this is it.

This Cotton Calico Triangular Bandage is made from washable, non-stretch cotton calico — stronger and more durable than non-woven disposable versions, and reusable after washing. At 110 x 110 x 155cm it is the full standard size, with enough fabric to work properly across adult limbs without improvisation.

• Full-size 110 x 110 x 155cm — works properly across adult limbs Size matters with a triangular bandage. An undersized bandage cannot form a proper arm sling for an adult without modification — the corners do not reach and the support is compromised. At 110 x 110 x 155cm this is the full standard size, cut to work correctly for the techniques it is designed for without having to improvise around insufficient fabric.
• Cotton calico — washable, non-stretch, stronger than non-woven alternatives Cotton calico does not stretch under load, which matters when a bandage is being used to immobilise a limb or support an injury. Non-woven disposable triangular bandages tear under tension and cannot be washed and reused. The calico construction is washable, durable, and maintains its integrity through repeated use and laundering — the correct choice for a kit that will see real use.
• Multiple applications — sling, immobilisation, dressing holder, splint securing Arm sling and broad arm sling for upper limb injuries. Folded as a broad bandage to secure splints or hold dressings in place. Used in snake bite pressure immobilisation as a supplementary bandage over the compression bandages. Improvised tourniquet in extremis. Head bandage for scalp wounds. The triangular bandage is the most versatile item in the kit — knowing how to use it correctly is a core first aid skill.
• WHS mandatory — required in every compliant workplace first aid kit Triangular bandages are a mandatory inclusion in WHS-compliant workplace first aid kits under the SafeWork Australia Code of Practice. A kit without one does not meet the standard. Reusable after washing — replace if torn, contaminated, or no longer fit for purpose. Ships from Dubbo, NSW within 2 business days.
