Actually the bag is quite nice, although a puzzle to get setup at first.
It has two layers - silver metalized cloth outside and black inside.
When I first used it, I loaded all my film with it, color, B/W and IR
outside on a table in a campground.   When I got back from the trip and
processed it, some of the IR was badly fogged - even under the film
holder rails.  I then loaded a holder with unexposed Tmax on one side
and HIE on the other.  I took the bag and sat in full sunlight on the
back porch.  In the bag I pulled both slides and rotated the holder for
10 minutes.  When I processed the film, the Tmax was completley clear
and the HIE completely exposed.

The bag I uses is made by Tundra - an el cheapo at $20 but works fine
for HIE - so much for 'better is more expensive'.
