APEXINNO A3 Ultra-Light Head Strap for Meta Quest 3/Quest 3S Accessories,3.17oz Adjustable Comfort Strap,Most Comfortable for Lying Down

Thanks! Thats good advice. So, just so I understand, with the GC F3 , and having those "removeable light blocking attachments" on the sides removed, so the air vents are open, you still have fogging problems? But if you remove the nose piece, you no longer have fogging problems? Good call on the Halo strap, I already have something similar (elite battery strap) for my Quest 2, but I have got the quest 3 explictly for a long (months) travel work trip, so I can keep fit. Going for a lightweight, small packdown solution. Have ordered this strap - its basically a clone of the Apple Vision Pro headstrap (https://www.amazon.com/dp/B0FXFFMJVK?ref=ppx_yo2ov_dt_b_fed_asin_title)
