Profiling
The profiling method of construction
is used within the Softie and Softie Elite range of Sleeping bags.
Profiling is our name for the development of a 'no stitch through'
system of the sleeping bag construction. It is perhaps the most
revolutionary development in the manufacture of sleeping bags
to date.
Traditionally, all synthetic sleeping bags have to be quilted,
that is the outer or the inner fabric stitched in the insulation
to give it stability and prevent it from moving, when compressed
or washed.
Whilst developing new resins to enhance the softness of our
bags, together with Jacob Hardi, we came across a special blend
which gave a remarkable degree of strength to the structure of
the fibres, so strong in fact, that the fibre would support itself
in the bag, allowing us to remove all the stitch lines and the
cold spots that occur at each constriction of the insulation.
Stitching also restricts the re-loft, the recovery of the sleeping
bag when unpacked. The sewn line holds back the fabric and the
filling. We estimate that the profiling we have increased the
loft of our bags by 30%, providing a significant increase in
warmth without actually adding anything to the weight or the
pack size.
A word of warning, many other sleeping bags may look profiled
but check to make sure that they are not poor imitations using
loose covers to mask inner quilting.
