Shopper will this be good eith the 3.7 spare-air? Is the mouth piece cover and lanyard come with the holster or tank??
CLARENCE S There are a number of typos in your question, but I will try to answer what I think you are asking... I believe the holster you are looking at is for the 300 only. The 170 is about 1/2 the height of the 300, and has a different holster part no. A mouth piece cover and a lanyard do come with holster package. They also come with the original spare air retail package if you bought your spare air that way. The holster listed separately is intended as a replacement for a lost or damaged holster or as an upgrade for folks who have an older style holster. Spare Air has supplied a number of different holsters over the years.
MIKE E It works great I have mine strapped to the side of my tank Velcro works great two years of use mounted upside down lanyard is a very thin cable I used a gear keeper works much better mouth piece comes with holster and lanyard
BRYAN H Yes, this is a good solution to the original holster falling apart. I have two spare airs, and I bought two of this item. It's a big upgrade from the original holster. You'll like it. The mouth piece cover, straps, lanyard etc. all come with the holster. The tank only has the regulator and mouth piece attached to it.
