Apacs Lethal 63 Badminton String

The Apacs Lethal 63 is a thin 0.63 mm badminton string built for repulsion, feel and a crisp hitting sound. The thin gauge bites the shuttle for sharper attacking shots and a lively response, which is why it suits players who want power and control over maximum string life.

Quick answer

A 0.63 mm multifilament repulsion string, 10 m set, China-made. Great feel and hitting sound for attacking players. Being thin, it trades some durability, so it is not the choice if you break strings often.

Specifications

Who it's for

• Attacking players who want repulsion and a sharp, crisp sound off the string bed.
• Players who value feel and control and are happy to restring more often to keep it.
• Anyone wanting a budget alternative to thin-gauge premium strings like Yonex BG66 Ultimax.

Who should skip it

• Frequent string-breakers and hard hitters who want durability. A thicker string such as the Apacs Lethal 66 lasts longer.
• Players who prioritise string life over feel. Thin gauge always trades some durability for response.

Lethal 63 vs Lethal 66

Same Lethal family, different priorities. The Lethal 63 (0.63 mm) is thinner, so it gives more repulsion, feel and sound, with shorter string life. The Lethal 66 (0.66 mm) is slightly thicker, so it lasts longer while still hitting well. Pick the 63 for feel and power, the 66 for durability.

FAQ

What gauge is the Apacs Lethal 63?
0.63 mm, which is a thin gauge. Thinner strings give more repulsion and feel but wear out faster than thick ones.

Is the Lethal 63 durable?
It is a feel-and-repulsion string, not a durability string.

What tension should I string it at?
Tension is personal. Most players sit around 24 to 28 lbs. Higher tension gives more control; lower tension gives more repulsion.
