Help Identifying BaseLayer brand

Earth Sea Sky maybe? Been around since 1990 so the timeframe fits.

How about Thermal Tech? www.thermatech.co.nz But could be one of numerous options...

There was a brand of thermalwear that was a mix of polarfleece and polyprop, sold 20 or so years ago. Here are two photos of my friend Kay wearing the top/leggings... https://flic.kr/p/uzQack https://flic.kr/p/un4U7b Not sure if they made garments with vertical stripes… I'll check that.

OK just heard back from my friend Kay… she said they are striped; thin green and black vertical stripes with purple polarfleece on shoulders, knees etc. They were called Bees Knees, made in NZ. Factory was in Dunedin, taken over by Macpac or Fairydown. Looking at 30 years ago now.

was it alp sports selling their own branded thermals or was it bivouac by then?

I think you will find the brand was made in Dunedin as Wilderness Equipment who then sort of merged with Macpac who at the time did not make clothing to form Macpac Wilderness Equipment. They continued to used the Wilderness name and logo for a number of years (a squiggly running man). Macpac/Wilderness made Bee knees which were I think a mix of lightweight fleece and Geothermal (their branded thermal fabric - a polyester/polypropylene mix at the time). Pretty much all the local made polypro (Alp Sports and Bivouac) were and are horizontal stripes.

@Amino, I agree with @Bivouac Gary in that the thermal baselayer you're thinking of is the Macpac Wilderness Geothermal. I found them to be fantastic thermals. Compared to most of the polypro available at the time, they were thicker and warmer, not so stretchy and open as they had a a much tighter, more wind resistant weave/knitting. I still use a Geothermal long sleeve top as my bush bashing top as they are very hardwearing and most plants (except bush lawyer!) seem to slide off without catching. As an aside, when Macpac reintroduced the Geothermal brand back into their thermal range a few years back, they very quickly had to change their marketing to include that the new Geothermals (100% polyester) were not the same as the old Geothermals.

I have an ancient pair of 'Wilderness' leggings which I've been using most winter days under shorts, around the property, for years. They are now full of holes but still going strong. 'Runs' don't seem to affect their strength. I have more modern ones which only last a few years. They don't make em like they used to! lol

The bee knees were bad news if they got wet. The polarfleece holds water and would be a real drag as well.
