Wetsuit

when using the wet suit with other low end attire you can get 30% or more radiation protection. which could serve as an early game hazmat suit which will protect you in most rad towns
be careful it wont protect you from every rad town

Its body and leg clothing at the same time.So opens more slots for shoes, bandama and gloves. Making it an intresting choice for a full equipment, even if it lacks any defensive stats, you can get something from your extra slots.

The wet-suit can achieve 100% head melee protection, by using it with a riot helmet and bandana. It can also achieve 85% melee resistance in the chest by using a hide poncho and sheet gloves, making it a very effective outfit for early game melee fights

This is your best choice for snow terrain and freezing water. Together with miner's hat, bandana mask, tactical gloves, boots and hide poncho, wood armor pants, you get to 53% protection against cold, or together with jacket can get you to 55% protection against cold, which can help you survive in all snow conditions day and night, while being immune to getting wet (which is especially useful in freezing water).
It also provides enough radiation protection that together with radtea you can run all rad towns. In the above combination with jacket you get to 33% rad resist, or together with hide poncho and wood armor pants you get to 41% rad resist. If you replace miner's hat with Riot Helmet, you will have 53% cold protection and 44% rad protection, but you will loose the night's light advantage for a small unnecessary rad protection and physical (animal, explosion, melee) protection.

it seems the melee resistance also applies to the head, you can wear this with a riot helmet and bandana to achieve 100% melee resistance (for your head only).
