The Short Answer: Pick by Coverage and Compression
The Compression Plus Tank and Compression Plus Top share the same 20% stronger compression than TomboyX's original compression styles, but they differ in shape and coverage. The Tank is a full-length scoop-neck style with Power Mesh lining and a clean-finished hem, designed to stay put and layer under shirts or wear alone. The Top offers full coverage with a scoop neck, a stay-put chestband, and Power Mesh lining in front and back for smoothing. Both come in inclusive sizing XS–6X, are OEKO-TEX® certified, and use the same fabric blend: 50% recycled nylon, 29% nylon, 21% elastane, with a 75% recycled polyester / 25% elastane lining.
If you want a longer base layer that doubles as a standalone top, the Tank is the clearer choice. If you prefer a classic compression top with a secure chestband and full torso coverage, the Top fits that role. Neither is a binder; both are compression tops, so choose based on the silhouette you find easiest to wear.
Key Specs That Affect Your Decision
- Compression Plus Tank - Black: Full-length tank with scoop neckline and Power Mesh lining; clean finished at hem. The longer length and finished hem make it easier to tuck or wear untucked without rolling, and the scoop neck layers neatly under shirts.
Compression Plus Tank - Black - Compression Plus Top: Scoop neck with Power Mesh lining in front and back; signature stay-put silky soft chestband. The front-and-back lining plus chestband provides smoothing and a secure feel, which matters if you want consistent coverage across the chest and back.
Compression Plus Top - Compression Plus Tank - Black: Fit note: If you love the original Compression Tank, expect 20% more compression; size up for a similar fit and feel. Existing fans of the original Tank should adjust sizing to avoid an unexpectedly tighter fit.
- Compression Plus Top: Fit note: If you love the original Compression Top, expect 20% more compression. The same sizing caution applies if you are upgrading from the original Top; the Plus version is intentionally stronger.
Tank vs Top: How They Differ in Wear
- Length and coverage: The Tank is full-length, reaching further down the torso, while the Top offers full coverage with a scoop neck and chestband. Choose the Tank if you want more length for tucking or wearing alone; choose the Top if you prefer a classic cut that stays close to the body.
- Layering: Both are designed to layer smoothly under clothing. The Tank's scoop neckline and clean hem help it sit flat under shirts, while the Top's chestband and front-and-back Power Mesh lining add structure that may feel more secure under looser tops.
- Standalone wear: The Tank can be worn on its own as a full-length top. The Top is also suitable for wearing alone, but its compression top silhouette may read more like a base layer depending on styling.
- Compression feel: Both provide the same 20% stronger compression than the original styles. The Top's chestband may give a more focused feel across the chest, while the Tank's even compression is designed not to ride up.
Sizing Advice: Start With the Size-Up Rule
Because both styles are Compression Plus, the catalog explicitly advises sizing up if you want a fit similar to the original Compression Tank or Top. If you are new to TomboyX compression, start with your usual size in the Plus line, but be aware that it will feel firmer than the original. The size range covers XS–6X, and the Top also offers 3XS and 2XS in Black, so smaller sizes are available if needed.
If you are between sizes or prefer less compression, sizing up is the safer choice. The fabric blend includes 21% elastane, which provides stretch, but the intended fit is compressive. Keep in mind that the Tank and Top have different silhouettes; the size-up rule applies to both, but your preference for length and chestband feel should guide your final pick.
Materials and Care: What the Catalog Confirms
Both products share the same material composition: 50% recycled nylon, 29% nylon, 21% elastane, with a lining of 75% recycled polyester and 25% elastane. They are OEKO-TEX® certified and described as breathable for all-day wear. The Tank has a clean-finished hem, while the Top features a silky soft chestband.
The supplied information does not include specific washing or drying instructions for either style. To preserve the fabric and fit, follow the care label on your garment. As a general practice, wash compression garments gently and avoid fabric softeners, but confirm with the label before acting.
Making Your Choice
If you want a longer, full-length layer that can be worn alone or tucked, the Compression Plus Tank is the practical pick. If you prefer a compression top with a secure chestband and front-and-back smoothing, the Compression Plus Top is the better match. Both deliver the same stronger compression and inclusive sizing, so your decision comes down to coverage style and how you plan to wear it. Remember to size up if you want a feel closer to the original TomboyX compression pieces.
