The new golden-brown-with-brown-piping sleeper suits are much nicer than the old grey ones, which were nice enough. The new ones have a bit of lycra in the fabric, so they are stretchy, and it's a richer fabric that feels warmer on the skin.

FYI, the sizes are still very generous. On my last SQ 001, the load was very light, and they only had small and large size suits. I knew large would be a tent because in the past I've taken mediums, so I gave the small a try this time. It fit perfectly on me (6', 170 lb, fit guy). So you might get away with a size smaller than they offer you at first.
