Frequently Asked Questions
Q: What's the difference between SGE 400/3 and SGE 400/3BB? A: The SGE 400/3 has a silicone face seal. The SGE 400/3BB has a butyl rubber face seal, which provides superior resistance to chemical warfare agents (nerve agents, mustard gas) and meets stricter CBRN requirements. The 400/3BB is also slightly lighter. If you need maximum chemical protection, consider the 400/3BB version in our NBC Protective Kit.
Q: Why is butyl rubber better than silicone? A: Butyl rubber is impervious to nerve agents (sarin, VX), mustard gas, and other chemical warfare agents. Silicone provides good protection but doesn't meet the same military CBRN standards. Butyl rubber also has 200x better vapor resistance than natural rubber.
Q: What filters work with this mask? A: Any 40mm NATO threaded filter (EN148-1 / DIN 3183). We recommend our Multipurpose CBRN 40mm Filter ($54.95).
Q: Is this the same mask in the Tactical NBC Protective Kit? A: Yes. The Tactical NBC Protective Kit ($495.99) includes the SGE 400/3BB mask plus a filter, Tychem chemical suit, butyl gloves, overboots, and carry bag.

Great Ball
Size: 6 Inch, Color: Red
Our Little Goldendoodle Loves this ball & I like that it has so many straps to grab so I'm not getting the slimy part. It does not come already inflated so make sure you or a neighbor have an air compressor to blow it up because even though it came with a little pump I can't imagine how many weeks I'd have been pumping that without noticing any difference.

Virtually indestructible
Size: 8 Inch, Color: Red
Long lasting ball for a large dog. Bought the first one a few years ago. Its been outside all this time, still full of air and was virtually impossible for my large dog to destroy it. The weather affected the surface so ordered a new one. This has outlasted all the other balls.

Great toy for larger dogs
Size: 8 Inch, Color: Pink
This is holding up pretty well with my Great Pyrenees pup. She was able to pull all of the tags off-but the ball is intact for several weeks!

So much fun
Size: 8 Inch, Color: Pink
Best money ever spent hours of fun. We have 3 dogs. They all love to play with this toy. We got the size 3 large is what we ordered. I'm not going to lie I thought it would be bigger when I ordered it. Two of our dogs are large breeds and the other is medium. It's not too big for the medium to play with it. It comes with a ball pump included so convenient. The little tabs are very durable. I can't recommend this enough. This has no squeaking or any sounds. It's nice that you can play with your four legged companion or you can have them play tug or just enjoy pushing the ball around. It is very versatile in play and stimulation.
