Climalite Pullover. These look good and I am thinking of one. At about 200 gms it looks excellent. http://sleepingbags-cumulus.eu/uk/categories/jackets/climalite-pullover-599389?gid=55&vid=1 The price is excellent. My query is on sizing. Wondering if anyone has one and info on sizing please? I have emailed them and am waiting but have seen some suggestions on the down version of snugness in the arm pit region due to possible sizing anomalies? I want to avoid too large a size and swimming in it. Ta.
