      Initial impressions are good. I wanted something lightweight and comfortable to hold my nods. This does that well.

      I Was Impressed by the Ease of Setting Up Helmet

      Posted by Troy Bostick on 24th Mar 2022

      I was impressed that the helmet shipped with pads already installed in the helmet and was fortunate that they fit. However, if they don't fit you - they can be easily swapped out by using the Velcro...

      Does its job well

      Posted by Steve on 23rd Nov 2021

      Got it in the mail, and it fits my head well. Pretty good price for the quality and I can mount my Wilcox G24 mount with a PVS14 on the end solidly. No complaints here.

      Shipping was fast, the bump was great. Have it set up with pvs14 currently and been using it a few hours every night. Everything works as expected and retention system works well.

      First time buyer more than satisfied

      Posted by John on 15th Aug 2021

      Helmet came in promptly and packaged well. Included a nice cover that I was not expecting. My first time ordering from this company but for sure will not be my last. Thank you for a good transaction and a great deal as well.
