Collection note: No year is stated; the page only shows a 'New' tag. Level is null because the page gives no playing level. 'Player Typology: Technical Striker' describes a playing style, and the description says 'Ideal for competitive players' and 'take their game to the highest level', which are not level labels. Weight min and max are calculated from 365 g +/- 10g. Balance is given only as 270 mm, with no word for it. There is no Touch or Feel spec line. The core firmness comes from the Benefits text ('medium-hardness EVA rubber'), and 'medium-hardness' could also be read as medium-hard. The word 'Soft' in the model name refers to the Soft Carbon surface, not the core.
How our estimates work
These ratings are calculations from published specifications, not measured playing results or our play tests.
Not published for this racket: balance. Each missing input counts as the neutral midpoint, so treat these ratings as less certain than for a racket with all five.
- Power 68 = shape (diamond) 45/45 + balance (not published) 17.5/35 + weight (365g) 10/20 = 72.5 points, placed on the 10 to 90 scale
- Control 26 = shape (diamond) 0/60 + balance (not published) 20/40 = 20 points, placed on the 10 to 90 scale
- Handling 50 = balance (not published) 25/50 + weight (365g) 25/50 = 50 points, placed on the 10 to 90 scale
- Forgiveness 24 = shape (diamond) 0/45 + firmness (medium) 17.5/35 + face material (carbon) 0/20 = 17.5 points, placed on the 10 to 90 scale
- Comfort 40 = firmness (medium) 20/40 + face material (carbon) 0/25 + balance (not published) 10/20 + weight (365g) 7.5/15 = 37.5 points, placed on the 10 to 90 scale

Shops sell this model as their 2027 racket (seen as “Babolat Viper Soft Juan Lebron 3.1 2027” in the SPORTLET - Sport di racchetta product feed, 1 November 2026). Babolat’s own page prints no model year, so the year is the shops’ label, not the maker’s.
