You do not need much in the way of cold weather clothing. The water proof pants are the most important. I got mine for ARCTIC at REI for around 60 to 75. I am sure Ngaire can provide good info in this area. You may have most of what you need. It gets toward the cold side in Houston in the winter. The one item I am going to take I did not take on ARCTIC is a balaclava to keep my ears warm. It is actually quite warm on the ship. On arctic it was shirt sleeve weather. Brayden wore basketball shorts many days when playing hearts. Oh to be a teenager again.
