Tess Mono Part by Ellen Wille
Tess Mono Part by Ellen Wille: A Polished Straight Bob with a Secure Fit
Clean lines never go out of style. Tess Mono Part by Ellen Wille is a polished, mid-length straight bob with a natural monofilament part and an extended lace front, and it's built with Ellen Wille's new Secure Fit silicone-coated wefts for confident, all-day comfort.
Tess launches on November 2, 2026, as one of three new Secure Fit styles in Ellen Wille's Hair Power Collection, alongside Demi Mono and Elle Mono. It's the straight, sleek option of the three.
A Sleek, Swingy Bob
Tess has smooth, straight lengths and a clean, classic shape. The crown measures about 8 inches, the sides 7.25 inches and the nape 4 inches, with a 4-inch front. The result is a neat, swingy bob that looks put-together from every angle, polished enough for work and easy enough for every day.
What "Secure Fit" Means
The headline feature of this launch is Ellen Wille's new Secure Fit silicone coating on the wefts. Instead of relying on tension alone, the coated wefts grip gently where the cap meets your head, giving a reliable, non-slip hold that stays put through a busy day. It's designed for comfort as much as security, so the cap feels settled without feeling tight.
Mono Part and Extended Lace Front
Tess has a monofilament part: hand-tied hair on a sheer, scalp-like base right where the part shows most, so it looks natural up close. The extended lace front reaches a little further back than a standard lace front for a believable hairline, and the wefted back and sides keep the cap light and breathable.
Heat Friendly Fiber
Tess Mono Part is made with Ellen Wille's Heat Friendly synthetic fiber. It holds its sleek shape out of the box, and you can add a gentle bend or smooth the ends with low-heat tools. At just 3.3 oz, it's the lightest of the three new styles.

Caring for Tess Mono Part
Wash Tess Mono Part every 10 to 14 wears in cool water with a shampoo and conditioner made for synthetic fiber. Blot gently with a towel, never wring, and let it air dry on a wig stand so it keeps its shape. Detangle only when dry, working from the ends upward with a wide-tooth comb. Because the fiber is Heat Friendly, you can refresh the style with low-heat tools once it's completely dry; use a heat protectant made for synthetic fiber and keep the setting low. Our Wig Fiber Guide has the full details.
Frequently Asked Questions
What is a mono part?
A mono part is a strip of hand-tied monofilament along the part line. It looks like natural scalp where the part shows, while the rest of the cap stays light. A full mono top, like those on Demi Mono and Elle Mono, extends that natural look across the whole crown for more freedom in where you part.
Who is Tess Mono Part best suited for?
Anyone who wants a classic, sleek bob with a natural-looking part and hairline. It's a lightweight, low-maintenance choice for everyday wear, including for thinning hair or hair loss.
