Drek, if you decide on ESS. The
best price in
Canada. I just got one the past summer. They have all styles of ESS.
Note: This is a real tactical store, I've been there in person to purchase my ESS turbo fans. Plus I wear glasses and also purchased the prescription insert. Great product. My whole team uses them now.
After a summer day of fog in my JTs, ESS turbo fan and ESS crossbow was my solution.
Great store,
