Great as usual in regards to their selection. Hoping to see many items restocked again at some point but otherwise always a great place to get niche gear from. Shipping took a lil long, but maybe i need to pay attention to that notice next time (lol).
Purchased with confidence and was kept informed on the order.
I ordered an FM12 gasmask and the sizing chart included on the page was crucial for helping me chose the right size. After placing the order, I was kept informed on when the item had shipped.
Shipping is slow, but it still got to me. Product was in fantastic shape for the price you pay!

A few items were missing from order, but made right
A few items were missing from order, when contacted I was answered very promptly and the items are being shipped. I understand mistakes happen and they're going above and beyond to remedy the situation. I highly recommend them for purchasing surplus equipment/gear.
I bought an AVON FM12 gas mask from the site and received a tracking number by UPS that said “the label was created” for a solid week and a half. I was concerned and commented under an insta post about the delay and was reassured that the order was processing. Managed to get a hold of it and it was a mint respirator, no issues whatsoever. Will be buying from this site again, it has earned my trust.
It took two weeks to ship instead of the 4 days said on the website however once shipped it took less than a week to get to my house shipping cross country
The gas mask I ordered (msa advantage 1000) arrived in amazing condition with only some light yellowing on the visor.
My only complaint with this order and company is that it took a while for them to ship it.
It shipped within a week. Condition is almost new, XL is snug but fits great. I'm ordering a second one for my son

Hidden Gem website
Found this website by accident and ordered a gas mask thinking I'd give them a shot and it paid off! It shipped fast, was in awesome condition and saved me a good bit of money. I'll be ordering something else from them in the future.
I promise this isn't an AI ad, haha.
Great items, great deals, great shipping
Bought the last MSA Millennium in medium and am very happy with my purchase. It even shipped out and got to me in great time.
Was skeptical at first due to the low reviews of the site but I am very happy to say that I got a very nice item and will definitely do business with them again. Just wish I found them before the Peltors sold out! If they're ever back in stock, I'm grabbing some and more.
Very happy to support a smaller company for my collecting and cosplaying! 10/10
They were responsive related to questions and shipping was timely for my orders expect one when UPS did not pick up their packages. Got my hands on a FM12 that was in great condition. If they have anything I'm looking for in the future there's a good probability I'll order from them again.
