A onsie or full suit helps keep your body heat circulating around the suit, a parka and pants gives you cold kidneys. The Aldi onsies cost about $110 less than the Hepworth onepiece Freezer Suits that Geoff sells. The Hepworth suits are also available retail through some workwear stores. I haven't used the Aldi onsies just the hepworth's.
Has anyone used the aldi onsies standing/walking on grass in a heavy dew? They look like they'd absorb water around the feet. In a dry observatory, they look like they'll work fine.
I used a Hepworth freezer suit and Neos explorer over boots (purchased separately for about US120 from NEOS in the USA) in the arctic. Underneath, I only wore a pair of tracksuit pants and a tee shirt. One night in north Norway (latitude I wore it for 6 hours at -12 to -14C watching aurora without a warm up break. Then on Svalbard (latitude +78) Then I watched a solar eclipse for 3 hrs with the temperature around -23C. I was completely comfortable the whole time. Even had to unzip and let out some heat from time to time. Others wearing very thick down parkas and insulated pants were freezing. I do have a warm metabolism, I wear a tee shirt when others are wearing fleece.
Around Canberra during the winter - down to -5C I usually have to keep it unzipped unless it's windy. I haven't used the overboots around the ACT. Maybe this winter. Hepworth Suits are a top product and they work really well. They are also resistant to moisture. The only downside is that they are bulky to wear and to store. By way of context, I have a warm metabolism & good circulation, my feet and hands usually remain warm in the cold unless I get dangerously cold - hypothermic. If you are cold, it's harder to concentrate.
I have no association with Hepworth or Geoff other than being a happy customer.
