Equinox Guard has a thin inner liner to act as a bug shield, outsider tucks over your boot shoes and the inner liner you pull your socks over. I’ve never had any issues regarding bugs while wearing my EG’s.
Durability and breathability are there, too. I own several pairs and landscape professionally in Equinox Guards, Kuiu Tiburons, Wrangler ATG’s and Carhart pants.
Overall the Sitka EG are my favorite, followed by Kuiu Tiburons, then Carhart’s with Wrangler ATG’s at the end of the pack.
I have crawled through blue rug juniper beds that were 3-4’ in height, removing briars for 6 hours and the Sitka EG’s didn’t rip, tear or even pull. They’re significantly more durable than I anticipated.
