Insulated Suits

One-piece down suits are the ultimate in protective gear for extreme expeditions like Everest or the Poles. Many people favour the versatility of the split system (jacket & pants), particularly if they are using the same kit for different kinds of expeditions. But as a secure system for a big expedition one-piece down suits are hard to beat. If you are uncertain which you favour, the arguments for each system can be seen in the FAQs section of our Gear Adviser website (under "one-piece suits").
