Not to get way too in the weeds, but GSM isnt really the best metric for quality (or warmth). I’m just a noob in all of this, but the starting staple length of the fibers, the processing (combing vs just carding), spinning (open ended vs ring spun), fiber diameter, ply, and twist, and knitting technique come into play. Then for some fabrics, you have treatments added after the fact, so you could have a 300 GSM fabric with 75 GSM of wax on top. You could even have multiple layers of fabric in the final garment.
I’d mostly just try to look at the GSM to compare between offerings by the same brand.

















I’m actually a big fan of both of those creators. One thing that’s struck me from their work is that not enough companies who are doing things the “right” way are actually taking credit for it.
There might be a couple of statements about the material, but not much. I think partially they want to make sure they have flexibility as supply chain issues come and go, but it provides cover for PE to come in and hollow out a product and keep selling it under the good name.
If they told you all of the little details that drive the cost and lead to the quality, the moment those things start disappearing from the postings, you would know something is wrong. Like a canary in the coal mine.
