The Snow Suit gives +20 fam weight that decreases over time, losing 1 every 4 combats, down to a floor of +5. It can also be "decorated", which gives you a choice of the following (stolen from Star18 on the official forums):
-wearing the nose may give +item (im not sure it could give meat) and drops the carrot occasionally that can turn into a spleen item that gave me 4 adv for the cost of 3 spleen.
-wearing the goatee gives minor health back
-wearing the hat gives minor Mp back
-wearing the eyebrows makes ur familar attack with physical damage(my 20lb fam attacked for 6)
-wearing the smirk makes ur familiar attack with cold damage (my 20lb fam attacked for 2)
The extra drop rate will need to be spaded, the rest seem pretty marginal. The nose makes the following item drop after combat:
--------------------
6151 carrot nose 129603339 snowcarrot.gif usable t,d 5
# carrot nose
--------------------
Using the carrot nose gave me this item:
--------------------
6154 carrot juice 168944703 shot.gif usable t,d 5
# carrot juice
--------------------
Carrot Juice appears to be a spleen item, but my spleen is already full.
