Both Tonal sports bras cost under $55, but they differ in color range and support. Here's how to pick between the Sara Airweight and Monah Rigor.
Quick Answer
Choose the Sara Airweight Bra if you want a lightweight, low-profile bra with two color options and a smooth silhouette under clothing. Choose the Monah Rigor Bra if you prefer a classic black performance bra with a slightly lower price and a fit built for focused training. Both come in XS–XL, so your decision really comes down to color preference and how much coverage you want.
What Sets These Two Tonal Bras Apart
The Sara Airweight Bra and Monah Rigor Bra are both part of Tonal's Performance Shop, and both land in the same price range—$54.94 and $53.30 respectively. The Airweight is designed to feel light and nearly invisible under clothing, with a smooth, low-profile construction. The Rigor is a collaboration between Tonal and Splits59, built for performance-focused activities with a classic black look. Neither bra is better in every situation; they simply prioritize different things.
Color, Sizing, and Fit Details
The Sara Airweight comes in Black or Dark Cherry, while the Monah Rigor is only available in black. Both offer sizes XS through XL. The Airweight's lightweight design is meant to help you move freely during workouts, and its supportive fit works across a variety of performance activities. The Rigor is engineered for active wear and combines style with support for a confident workout. If you like having a color option beyond black, the Airweight is your pick. If you prefer a timeless black bra and want to save about a dollar, the Rigor makes sense.
How to Choose Based on Your Training
Think about what you wear over your bra and how you train. If you often layer a tank or tee and want a bra that disappears underneath, the Airweight's low-profile construction is a practical advantage. If you train hard and want a bra that feels substantial and performance-oriented, the Rigor's Splits59 collaboration and classic black design may appeal more. Neither product listing specifies impact level or fabric details, so if you need that information, check the product page or reach out to Tonal support before ordering.
