Very good cover, it fits well my Nexus Helmet.
Fits the N49 helmet perfectly. Also put a large size one of these on my 3M L110 (Combat II) helmet (.308 rated) and fits that virtually perfectly. I do not own night vision (yet), but the rear pouch will be extremely useful for battery packs and counter-weights. Also made of solid cordura nylon - not the mesh you can see through - which offers better physical protection of the helmet.
This helmet cover fits perfectly, and was easy to install. It performs all the functions you would want it to.
Initially I was planning on using a different cover for my 3M ULW that was designed for the Ops-Core SF/Maritime helmet, but after some searching on YouTube I saw that Agilite released these at Shot Show. I was hesitant at first with shipping from overseas but was pleased to receive the product in just a couple of weeks with no issues. The stitching is of good quality and the external velcro holds up well. The cover comes with Velcro stickers for the internal Velcro to stick too, helping to prevent the cover from shifting. I found this inner Velcro to not be very effective, but the way the rails attach to the helmet assists in keeping the cover in place. The bungee on top does a great job retaining my IR strobe, and the rear pouch helps tuck away the excess. I do wish the rear pouch had elastic spots designed specifically for CR123 and AA batteries but they still retain batteries well nonetheless. All in all it’s a quality product that has held up in multiple field training exercises.
