Which version of the weezle undersuit should I buy?

This depends on the type of diving you do, the type of dry suit you use, and how sensitive you are to the cold. The thermal properties of the Compact undersuit & Extreme undersuit exceed those of traditional undersuits. In contrast, the Extreme Plus undersuit breaks the boundaries of undersuit manufacture and is suitable for ice diving.

Although the Extreme and Extreme Plus undersuits are slightly bulkier, they remain more flexible than most undersuits, ensuring that movement is not restricted.
