We have designed this product for use in air rather than in combination
with a Weezle Undersuit. The Argon is filled with the same filling as an
Extreme+ Undersuit but with a ‘Ripstop’ Paratex outer and zipper fastening. This
comes in grey and black with a black lining. The collar has been made smaller
but is not removable and the two outer and one inner pocket all have the
security of a zip. The size range remains the same from Ex Small to Ex Ex Large.
