Need Personal BCD Fitting Help? Visit International Diving Centre in Vancouver to try on Aqua Lung BCDs in person, or call our expert dive team for personalized sizing advice.
Choosing the correct size for your Aqua Lung BCD is essential for optimal weight distribution, trim, and underwater comfort. Whether you are selecting a classic jacket BCD (Pro HD, Wave), a premium back-inflation model (Axiom, Dimension), a women's specific fit (Soul), or a lightweight modular harness (Rogue, Outlaw), use the dual-unit (imperial/metric) measurement tables below to find your exact size.
Wrapture™ Harness & Exposure Suit Adjustment Tips
Aqua Lung BCDs featuring the Wrapture™ Harness System wrap comfortably around your torso to transfer tank weight directly to your hips. When diving in Canadian cold water, measure yourself wearing your primary exposure protection (7mm wetsuit or drysuit). Aqua Lung’s extended adjustment webbing allows you to easily fine-tune your fit between thick cold-water undergarments and thin tropical wetsuits.

How to Measure for Your Aqua Lung BCD
- Waist: Measure around your natural waistline (above the hip bone, near the navel) where the main cummerbund rests.
- Over the Shoulder: Measure vertically from the top of your waistline in front, up over your shoulder, and down to the top of your waistline in back.
- Between Sizes? If your waist and height span two size brackets, select the larger size if diving primarily with thick cold-water suits/undergarments, or the smaller size for thin warm-water suits.
