I was given something similar to this when I lived in Japan. All the professionals seem to use them, so it was the first thing I bought for myself when I returned. I am in the garden every (no rainy) day and its the best garden implement I have ever owned.
However, your choice of secateurs is a good one.
I struggle because I have a giant noggin. Finally found a hat that fits (just). It was a bit expensive for my liking but it’s decent quality and the coverage is awesome. https://www.amazon.com.au/Coolibar-Mens-Shapeable-Wide-Brim/dp/B01F2F4RVK/ref=mp_s_a_1_6?crid=2C86QZM3QXIJH&keywords=coolibar+hat&qid=1666404710&qu=eyJxc2MiOiIzLjE5IiwicXNhIjoiMy4zNyIsInFzcCI6IjIuNTIifQ%3D%3D&sprefix=coolibar%2Caps...
Mosquito dunks also work amazingly against fungus gnats: https://www.amazon.com.au/Mosquito-Summit-Dunks-6/dp/B00LET25AE/ref=mp_s_a_1_3?adgrpid=83871262301&gclid=Cj0KCQjwhsmaBhCvARIsAIbEbH45viBcdZjnCR8bFVjq7y8sEjcYxAEpr20iYlog_IGQWjCL3uOgmmgaAgATEALw_wcB&hvadid=606526915634&hvdev=m&hvloc...
I seriously used these once and never had a problem again!
