Super 120s wool occupies the coveted middle ground in luxury suiting. With fiber diameters averaging 17.5 microns, it offers a noticeably softer hand than Super 100s while retaining enough structural integrity for regular professional wear. It is the fabric of choice for clients who have graduated beyond their first quality suit and want something that feels distinctly more refined without sacrificing practicality.
The fiber's fineness produces a fabric with a gentle luster and fluid drape that sets it apart from coarser grades. When a client runs their hand across Super 120s cloth, the difference is immediately apparent. The fabric feels alive, responding to touch with a softness that communicates quality before the suit is even constructed. Italian mills like Cerruti, Zegna, and Loro Piana have made Super 120s a cornerstone of their collections.
For tailors, Super 120s represents an excellent upselling opportunity. Clients who already own a solid Super 100s wardrobe are natural candidates for the refinement that 120s provides, particularly for suits intended for important meetings, presentations, or social events where appearance matters most.
The 120s Sweet Spot
In the hierarchy of Super numbers, 120s represents a sweet spot that many experienced tailors consider the best all-around luxury grade. Below 120s, the difference from standard wools is subtle. Above 120s, durability begins to decline more noticeably with each step up. At 17.5 microns, the fibers are fine enough to produce genuine luxury softness while maintaining the tensile strength needed for a suit that will be worn regularly. This is why many of the world's best-dressed men, from finance executives to diplomats, gravitate toward 120s for their go-to suits.
Construction Considerations for Tailors
Super 120s requires slightly more care during construction than coarser grades. The finer fibers mean the cloth is more susceptible to needle damage, so tailors should use appropriate needle sizes and ensure their machines are well-maintained. Hand-stitching is gentler on the fabric and is recommended for critical areas like lapels and collar attachment. The fabric responds beautifully to a full canvas construction, where the natural drape of the wool works in harmony with the horsehair canvas to create a chest that rolls gracefully. Fused constructions are possible but do not showcase the fabric's natural movement as effectively.
Drape and Movement
The defining characteristic of Super 120s is its drape. Where Super 100s hangs with a certain crispness, 120s flows. The fabric follows the body's contours more closely, creating a silhouette that looks sculpted rather than structured. This fluid quality is particularly evident in motion, where the jacket moves with the wearer rather than holding a rigid shape. For this reason, Super 120s is especially flattering in contemporary slim-cut styles that rely on the body's natural shape rather than heavy padding and structure.
Comparing Mills and Bunches
The quality of Super 120s varies significantly between mills. Italian mills generally produce fabrics with a silkier finish, achieved through extensive finishing processes including multiple rounds of shearing, pressing, and decating. English mills tend to produce a slightly crisper hand with more body. Both approaches have merit and appeal to different clientele. Zegna's Trofeo line, Loro Piana's Four Seasons, and Scabal's Royal collections are benchmarks in the category. Tailors should maintain relationships with multiple suppliers to offer clients the specific character they prefer.

Super 120s Wool FAQ
Not at all. While Super 120s is softer than Super 100s, it is still a robust worsted wool suitable for regular professional wear. The key is proper care: rotate your suits, use quality hangers, and allow rest days between wearings. Many professionals wear Super 120s suits 2-3 times per week for years without issue.
Typically 20-40% more expensive for comparable quality. A suit length of Super 120s from a reputable mill might cost $150-300 more than the equivalent Super 100s. The difference reflects the rarer, finer fibers required and the more intensive finishing processes. For many clients, the upgrade in feel and appearance is well worth the premium.
Yes, in lighter weights (7-8 oz). The finer fibers actually breathe reasonably well, and several mills produce dedicated summer-weight Super 120s fabrics. However, for very hot climates, a tropical wool like fresco or a linen blend may be more comfortable. Super 120s really excels in spring and autumn temperatures.
