tl;dr (ish): Firstly, sunscreen is king for staying cool over buffs and sun gloves. This assumes one is using sun screen on exposed skin. In direct sunlight in extreme heat pure white colors are king, avoid grays, greens, black, and anything dark. Lighter and warmer colors absorb less energy from sunlight. The loosest fitting oversizing you can learn to live with is always, ALWAYS cooler, and also prevent over-stretching the fabric causing loss in UPF value. In really extreme heat midday, going to ultra breathable shirts like the UPF 15-20 Echo isn't really cooler than a UPF 50 Crater Lake, assuming both the same color, due to a sort of greenhouse effect of light coming through thinner fabrics. The pure white Outdoor Research Echo oversized and the Mountain Hardwear Crater Lake Fogbank white are the coolest wearing I have experienced in extreme sunlight dry heat. Lastly, v-cut hoods are superior to scooba hoods assuming the user has applied sun screen to exposed skin. Mesh trucker-style hats compliment sun hoodies the best.

Color:

I've purchased most of the highest rated sun hoodies, and when I do, I often get the exact same size and model in different colors. I also use my sun hoodies for work and on cooler days I switch to a darker or green color to keep the temp just right under the sun. It's an absolute fact without really any gray area that pure white is king for staying cool. End of story. Even the slightest light gray builds up excess heat. Adding darker colors to fabric can increase UPF ratings, but is always inferior to just using more fabric in pure white. My thicker UPF 50 hoodies in white are vastly better under direct hot sun than my Echo hoodies in gray color tones even though they breath much better airflow wise.

White is tough to keep clean if you are thru-hiking. But it does clean up perfectly with one soak in oxi-clean. Since not everyone is thru-hiking, this isn't an issue for most cases. A white shirt will stay plenty clean on a week long trip, at least clean enough to still be superior in cooling to gray shirts.

Loose Fitting:

This is another variable that is just not at all debatable. The only argument for not wanting to oversize as much as possible is if you hate the feeling of extra clothing hanging around your body. It just feels strange at first, but the brain will get used to it, especially for anyone who was a kid in the 90's. You want perfectly fitting cloths for maxing warmth in the cold, and the opposite is true for the heat. Gotta go super loose. The body movement in loose clothes pumps air in and out regardless of how breathable the fabric is, so UPF 50 thicker shirts like the Crater Lake can still pump air like a champ when loose and flapping around. There is also the factor of when a breeze hits the shirt it causes it to flutter like a flag and this fluttering also pumps air in and out, quite rapidly. None of that happens with a shirt that is closer to normal size with no extra flapping. Along with airflow, loose shirts also don't stretch as much in places like the shoulders and retain the UPF rating better. Stretching the fabric quickly and instantly reduces UPF UV blocking, since there is literally less fabric covering the same area.

Greenhouse Effect:

At a certain point in extreme heat in direct extreme midday sunlight where the UPF 15 shirts like the Echo loose their temp advantage with their ability to breath better. The added amount of light coming into the fabric gets trapped inside and converted into absorbed heat that is now trapped for a little bit inside. A pure white UPF 50 shirt like the Crater Lake has worse airflow than the Echo but feels much cooler on the shoulders and head and anywhere flat facing the sun directly. The reduced light transmission on the Crater Lake compensates for the lesser airflow, and the two shirt end up overall about the same temp for the user, but one is providing much more UV protection. If the Crater Lake or any UPF 50 shirt has any color pigment and is not pure white, then it will likely never compete with a white Echo or even light gray or light yellow Echo. I can't wear my green Crater Lake past 75* F without feeling a bit cooked, but my white one in the same size is super good enough at 95+* F.

V-Cut vs Scuba:

I think the perfect hood for keeping cool is the v cut style that is open all the way down to the collar. I add a button or snap to the v cut hoods to convert them to more scuba hoods when not needing to keep as cool and just block more skin from UV. The v-cut does require more sun screen to compensate but the temp difference is massive. This is one reason why I think the Crater Lake Fogbank white color hoodie in the Women's model is superior to just about anything, assuming you can get it to fit loosely if you are a man. It has the v-cut hood vs the men's with a scuba type hood. As a big dude, I barely get enough flappage going with the XXXL, but it works. Arm length being short on women's might be the biggest issue for guys trying to fit in them, and the added draw cord and pocket are silly added weight that need to cut off for UL.

If you passed 3rd grade art class, you also have the skills to likely cut things with scissors. Scuba hoodies can be cut into v-cuts in less than 5 seconds. Then add a button if desired to put it back into scuba mode when needed. For the Echo, at least, I can attest that the fabric doesn't unravel itself if just left bare cut. It stays together pretty well on its own.

I go through lots of nitrile gloves for salmon fishing. I like the Gorilla Grip 6 mil from Home Depot. According to hospitals and first responders, the prices for raw supplies for making them is going to go up many fold, thus increasing costs and reducing supply, which is already starting to happen. (Thanks to Obama recently bombing oil-controlling countries /s)

There could be covid levels of supply shortages coming this year for gloves, so maybe stock up now before the retailers start seeing the tsunami coming over the horizon.

You can tell easily by the vegetation. It's clearly still the growing season there and they have not mentioned snow once. The things they were talking about is how the section of river is 100% done and they have to fill back in the hole before thinking of the next move up stream. For the amount of gold they have, it's possible there is much more coming depending on what they can do with getting things going above this current spot. They're not even thinking much of the next spot until the current one is cleaned up, as it is in the way of getting up high in the river.

I could be wrong, but these folks have proven they work until they can't work any longer.

That's not even taking into account the pay pile they have to work through which will easily double the gold total, at the least.

If they have enough time to do so much work on filming, I don't see them taking new people on which cuts down profit takes for the crew. If they can work out an efficient system for 4 people to go there and bang out 100-200+ ounces a year, then it's probably a solid operation at that point without having to hit the motherlode, although that would still be much welcome, haha.
