OL-THERMAL UNDERWEAR SYSTEM

UNIVERSAL-THERM and XTREME-THERM

 

Thermal isolation underwear system for dry suit

The UNIVERSAL-THERM is the ultimate base layer for use under a dry suit.

The XTREME-THERM’s two layers of high insulation, low bulk fabric, ensure exceptional levels of thermal protection.

Features

UNIVERSAL-THERM:

  • 3 pcs thermal underwear for dry suits made of spun synthetic fleece.
  • Made using Polartec® Powerstretch® which was originally developed for NASA, the UNIVERSAL -THERM traps a layer of air - a much better insulator than water - next to the skin, keeping the wearer drier and more comfortable.
  • The unisex range is designed to be worn under another Undersuit or on its own under a Trilaminat dry suit even in warmer conditions and provides astonishing warmth without contributing to bulk or buoyancy.

XTREME-THERM:

  • The XTREME -THERM’s two layers of high insulation, low bulk fabric, ensure exceptional levels of thermal protection.
  • Constructed with comfort and utility in mind, the minimalist design provides outstanding performance under dry suits.
  • In a layering system (in combination with the UNIVERSAL –THERM as base layer ), the XTREME -THERM is also suited for use underneath membrane and Trilaminat suits under extreme (-2° to 10° C) low water conditions.
  • Its special FST (Flat Seam Technology) was developed for outer-limits to avoid any irritation by using in tactical and long term operations.
