Drysuit Sizing Guide: Why Fit Consultation Matters Before Ordering

A drysuit is not a universal-size product. Fit affects comfort, mobility, seal performance, thermal layering and safety. For diving, rescue and cold-water professional work, ordering by a simple standard size can lead to poor movement, seal issues or insufficient room for insulation.

This is why TOB Outdoors Canada asks customers to contact us before ordering from our drysuit collection. A short fit review helps match the suit to the user and the intended application.

Measurements to Prepare

Before contacting us, prepare your height, weight, chest, waist, hip and foot size. If the drysuit will be used with thick thermal base layers, mention that as well. For professional or rescue applications, describe the expected environment and task type.

Why Standard Size Assumptions Can Be Risky

A drysuit that is too tight can restrict movement and reduce space for insulation. A suit that is too loose may feel bulky, interfere with equipment or create fit issues around seals. The right fit balances mobility, comfort and the dry barrier needed for the task.

Consider Undergarments and Footwear

Cold-water users often wear thermal layers under the suit. These layers affect chest, waist, hip and leg fit. Footwear and integrated boot sizing also matter, especially for divers and rescue users working in cold environments.

Application Matters

Technical divers, rescue teams and cold-water professionals may need different mobility and durability priorities. Tell us whether the suit is for diving, rescue training, rescue operations or professional underwater work.
