AV Chazelle Suit

Introducing the Chazelle: a new mid-weight oversuit crafted from 500 denier Cordura by Aventure Verticale of France.

Designed with comfort and flexibility in mind, the Chazelle offers more breathability and slightly less waterproofing than AV’s other new model, the Kriska—whether that’s a benefit or a drawback depends on your specific needs underground. The striking yellow color ensures you’ll stand out, even in the darkest environments.

All of AV’s new suits share a common spec: durable reinforcements at the knees, seat, and forearms in contrasting black Cordura, complete with drain holes to prevent water buildup. Storage is well thought-out with a single external chest pocket on the left, outfitted with internal gear loops to secure small essentials, plus an additional internal pocket on the lower right side—perfect for stashing items away from your chest-mounted gear. A fleece-lined collar adds a touch of warmth and softness.

Aventure Verticale recommends the Chazelle for dry, warm cave environments. That said, Cordura performs well in many situations—even in colder caves without excessive water exposure, especially if you manage your layering properly. Sometimes it’s better to stay cool and dry rather than overheat in a highly waterproof suit.

About the New Fit:

AV has overhauled their sizing system. The Chazelle is available in three cuts: Regular, Tall, and Curvy. You’ll find links to the updated size charts below, and we’re happy to help with fit questions if needed.

If you’ve worn previous AV suits:

• Regular is close to the original Titan cut, but with a slightly shorter torso.

• Tall has a longer torso, plus extended arms and legs—ideal for cavers with long limbs or anyone who needs more vertical space.

• Curvy replaces the former women’s Titan range, with thoughtful improvements. It offers more room in the hips and thighs, a narrower shoulder, and longer arms—all proportioned more practically. A medium in the Curvy range now matches a medium in Regular, eliminating the need to size up by multiple steps like in the past.
