Genuine Royal Navy No.3 Dress Trousers – Black – Various Sizes

Genuine Royal Navy issue No.3 dress trousers, available in a range of authentic military sizes and conditions.

These smart black trousers form part of Royal Navy No.3 dress/work uniform and are genuine British military surplus rather than commercially produced reproductions. Current surplus retailers describe them as genuine Royal Navy No.3 dress/work trousers, with typical features including side pockets, a rear pocket, zip fly and belt loops.

Their simple black military cut makes them suitable not only for service-related collections and uniform requirements, but also for formal wear, cadet use, ceremonial purposes and anyone looking for durable genuine military clothing.

Choose your condition

New / Unissued 

New military-surplus stock showing no meaningful evidence of previous service wear.

Minor storage marks, creasing or packaging-related characteristics may occasionally be present as a consequence of military storage.

Grade 1 

Previously issued or used but remaining in good, clean and serviceable condition.

Grade 1 examples may display light evidence of previous service, including:

• minor cosmetic marks;
• light fading;
• signs of previous laundering;
• service or ownership markings; or
• light general wear.

Comparable retailers currently describe Grade 1 Royal Navy No.3 trousers as good used/serviceable stock, generally without significant rips, tears, holes or stains.

Every pair supplied by The Old Kitbag is individually checked against the advertised grade before dispatch.

Understanding Royal Navy trouser sizing

Royal Navy trousers use the familiar British military three-number sizing system.

For example:

80/84/100

means approximately:

80 cm – Inside leg
84 cm – Waist
100 cm – Seat

So the sizing format is:

Inside Leg / Waist / Seat

Current Royal Navy No.3 surplus sellers also list these trousers using leg/waist/seat measurements in centimetres.

We recommend selecting your trousers using the actual MOD measurements rather than relying on Small, Medium or Large conversions.
