![I tested Caeleb Dressels new tech suit — heres what the data says
Caeleb Dressel left Speedo to co-design a tech suit with a brand most people have never heard of. I flew to Tenerife to test the DeBoer Dressel Speed 1.0 — against the Mizuno GX Sonic VI NV (my benchmark), DeBoers own Cove, and a prototype thats not out yet.
Two days of sprints in T3s flume system with Pablo Marcos at ProEnduranceLab. We measured VO2, blood lactate, muscle oxygenation (Moxy NIRS) and heart rate at constant pace — with stroke rate as the control variable to make sure its the suit doing the work, not me swimming differently.
This is NOT a review. Its a first-look at the data: objective numbers, side-by-side comparisons, and my first impressions of a suit designed by one of the greatest sprinters in history.
🔬 WHAT WE TESTED
→ DeBoer Dressel Speed 1.0 (Caeleb Dressels co-designed race suit — launched March 2025)
→ Mizuno GX Sonic VI NV (benchmark)
→ DeBoer Cove (DeBoers original race suit)
→ [PROTOTYPE] — youll have to watch next video
📊 KEY METRICS
→ Heart rate | Blood lactate | Muscle O2 saturation | Energy expenditure | Stroke rate
