The Current
A wetsuit that closes can still be too restrictive. Check normal breathing, shoulder movement, torso length and panel placement. You deserve a suit that works with your proportions rather than a joke about squeezing into the wrong size.
Wetsuit bunching behind the knees can come from extra leg length, low knee panels or incomplete donning. Seat the suit correctly before judging it; persistent thick folds call for a different cut or a professional alteration assessment.
A wetsuit should be snug without restricting normal breathing or the movements needed for your dive. Check panel placement, torso length and the exact model's measurements before deciding whether the suit is too small or simply not fully pulled into position.
Choose a wetsuit or drysuit around the full dive plan: water temperature, duration, surface conditions, layering, fit and training. A drysuit adds buoyancy-management skills; a thicker wetsuit is not automatically the right answer.
A wetsuit mobility check should include normal breathing, shoulder reach, bending and the equipment skills your setup requires. Seat the suit fully first. The observations in a fitting session describe your movement, not a universal performance result for the model.
