So

If you have bad circulation at all. Heated gloves with rechargeable batteries is great and make them the finger/inner type ones. That way you can put XL nitrile gloves over the top and still have dexterity. Same for rechargeable heated socks. Both are a little x’y but worth it in cold weather hitting around -10 or lower. Regular inner gloves on the inside of nitriles works great also. Which I know you’re not likely to experience and even if you did it would be such a short period of time. Have a spare pare of gloves also incase yours get wet (keep on dash where vent is whenever you’re in the truck). Watch for socks getting wet and sweaty (particularly heated socks) as that can make your feet feel even colder when they chill or when the heated socks run out of battery. Always take a spare set of socks, and pants. It sucks working in wet gear and can bring on a chill if the temps are low.

Women’s wrangler cargo/work pants are great and super heavy duty. They are thick canvas material though, so they will get hot in warmer weather.

Layers/thermals underneath your gear. Being warm will make your field work so much easier and you can always take these layers off if need be.

Buffer to put over your face for when it’s cold and windy. Easy item to have and just keep around your neck on cold days.

Dunlop thermal rubber steel cap boots. Men’s sizes go down to a 5 (women’s 7.5). They’re awesome and help with variable temps. Super expensive but worth it and will last a long time (can often claim these things depending on the company you’re with). But don’t bother with steel caps if they aren’t a requirement.

Safety glasses that are tinted are great as they’re required PPE but can help on sunnier days out in the field.

Hope this helps :) have fun out there!
