Jetpack details:

Take your Shell-Shock/Tectonic Stem to a new Paradigm.  Choose from a long or short mouthpiece extension and/or lengthen your hot end for a cooler temperature experience.  Plus it just looks damn cool!

**please note that the design of the tectonic incorporates two airflow ports to fine tune your experience.  Those airports can be closed but are not 100% sealed from fresh air even when fully closed a small amount of air will be introduced.  You can really get it almost completely tight but some have struggled with this.

Fantastic stem that taught me how to love dynavap.

I always heard how much of a heavy performer these style of devices are, but never seemed to achieve adequate results till now. I thoroughly enjoy using this thing, the second set of air ports can be swapped out if you purchase the jetpack attachments. I highly recommend getting both from Vgoodiez! Received a hot end extension that actually fit my tectonic without even asking for it! I was not aware the fitting of the extension was a common issue, so it really was a good save on their end. Absolutely satisfied.

Worth a Buy

Provides cooler vapor than your stock 'M. Ability to fully close, open airports. You can have 2 opened aiports on the stem or adjust to where only 1 is opened or have both closed(which is how I have mine usually). The mouthpiece does a good job at cooling the vapor- but if you find it too airy they do also have the Jet Pack attachment set that comes with 2 additional mouthpieces.

Final thoughts are that it is a nice stem and was well worth the money.

Great Buy!

This is an awesome stem! I love the fact that you can change out the 510 drip tip to personalize it to your taste. Thanks for the sale!

Great stem

Great service and fast shipping!!
