For the T-shirt I used both Grok and Gemini Deep Research. I basically just told them I was looking for an alternative to the Asket Lightweight T-Shirt that was more in line with its 2022 pricing of $50 (already on the high end of what I was willing to pay). They both called out that the defining features were Supima cotton and 120gsm density, and each independently recommended the Buck Mason Classic Pima Tee (with the only notable differences on paper being a slightly thicker 140gsm and anecdotal reports of inconsistent sizing). They each gave a few backup recs, but those were mostly not available or less aligned with requirements, so I just went for the BM and it met expectations.

For the shorts I used only Grok. Explained that I was looking for a similar fit and poly/elastane blend to an old Under Armour pair. Initially it incorrectly claimed that the same shorts were still for sale. Went back and forth with it surfacing a few options that weren't relevant and hallucinating specific claimed comparisons to the original pair in reviews that didn't actually exist. Ultimately it landed on another UA pair that was identical on paper other than a much larger stylized logo, and a cheaper one from a brand interestingly called "DEVOPS". Went with the latter and it turned out to be pretty much the same as the old pair, or at least as close as it seems I'm likely to find without a giant ad plastered on the side.
