Fabletics XXL vs. 2X: Sizing comparison [2026]

While their size labels may look similar, Fabletics and 2Xist cater to fundamentally different customers and offer distinct approaches to fit. Fabletics primarily designs trendy, inclusive women's activewear where XXL and 2X are often used for the same size range (US 18-22), focusing on flexible, comfortable fabrics. In contrast, 2Xist is a men's brand specializing in underwear and activewear, where a 2X fits a consumer looking for a snug, supportive silhouette with specific chest and waist measurements.

Here’s everything you need to know about their sizing differences to find the right fit for you.

Fabletics XXL & 2X Sizing

Fabletics is a popular activewear brand known for its stylish designs and commitment to inclusive sizing, offering a wide range from XS to 3X. Within their sizing system, the labels XXL and 2X are often used interchangeably to represent their plus-size range, providing a supportive yet flexible fit designed to accommodate various body shapes during workouts and daily activities.

• What it is: Sizing for a women's athleisure brand that prioritizes style, comfort, and body positivity.
• Key features: Trend-driven designs, performance fabrics with significant stretch, and a focus on supportive but not overly compressive fits. Many pieces feature high-waisted leggings and medium-support tops.
• Price: Moderate, with better pricing available through their VIP membership model.
• Sizing/Fit: An XXL or 2X generally corresponds to a US size 18-20, occasionally extending to a 22. Common measurements are a 38-42 inch waist and 44-48 inch hips, though this varies slightly between product lines.
• Pros: Highly inclusive size range, fabrics are stretchy and forgiving, flattering designs for many body types, consistent sizing across most collections.
• Cons: Sizing can sometimes feel generous, those between sizes may need to size down for a more compressive fit. The use of both XXL and 2X can be confusing on the website.

This sizing is ideal for women looking for stylish, functional activewear with a comfortable, forgiving fit that moves with the body without feeling restrictive.

Fabletics Sizing vs. 2Xist Sizing Comparison

Sizing Philosophy & Target Audience

The most significant difference comes down to the target audience. Fabletics designs clothing predominantly for women. Their sizing philosophy is built on inclusivity and flexibility, using stretchy materials to accommodate a wide array of female body types comfortably. The labels XXL and 2X are part of this approach, catering to the plus-size market with a fashionable, less-constrictive fit.

2Xist exclusively designs for men. Their sizing philosophy is rooted in precision, support, and a contoured fit that enhances the male physique. A 2X size from 2Xist is engineered based on specific chest and waist measurements to provide a snug, secure feel that's ideal for both athletic performance and everyday wear under clothing.

Size Charts & Measurements

On paper, the measurements look very different because they measure different things. A Fabletics 2X generally aligns with a US women's size 18-20, targeting a waist of approximately 38-42 inches and hips of 44-48 inches. Their charts focus on bust, waist, and hip circumferences.

A 2Xist 2X is based on standard US men's sizing. It typically corresponds to a chest measurement of 44-46 inches. The brand's size charts provide guides for waist and inseam for pants and shorts, but the foundational measurement for tops is the chest.

Fit & Comfort

The resulting fit and feel are worlds apart. A Fabletics piece in size 2X is designed to stretch and move with you, prioritizing comfort and flexibility. It hugs your curves supportively but rarely feels compressive unless it's from their specific high-compression line. The fit is generous and true to standard retail sizing.

A 2Xist garment in a 2X size, by contrast, is built to be form-fitting. Customers often note that the brand's activewear and underwear fit like a second skin, which is ideal for layering and preventing chafing. While comfortable, it is a distinctly snug fit, and those who prefer more room are often advised to size up.

Which One Should You Choose?

The right brand and fit depend almost entirely on who you are shopping for.

Choose Fabletics if:

• You are a woman looking for inclusive, stylish activewear.
• You prefer a comfortable, flexible fit with plenty of stretch.
• You wear a US women's size 18-22 and are looking for leggings, sports bras, and tops.
• You enjoy trend-driven styles and vibrant colors in your workout wardrobe.

Choose 2Xist if:

• You are a man seeking high-quality underwear, loungewear, or activewear.
• You prioritize a snug, supportive, and body-contouring fit.
• Your chest measurement is around 44-46 inches.
• You value durable materials and a classic, minimalist aesthetic over trendy designs.
