Viking XT250 Undersuit

Viking XT250 Undersuit


The ultimate base layer for dry suits. Designed to be worn under another undersuit, or on its own underneath a neoprene dry suit.

  • Provides astonishing warmth without contributing to bulk or buoyancy
  • Flat seams for next to skin comfort
  • Set consists of top and leggings

Originally developed for NASA, the XT250 fabric traps a very thin layer of air next to the skin, keeping the wearer drier and more comfortable.

Even when wet, the XT250 retains a significant degree of its thermal performance, so that the diver can continue his dive in relative comfort.
