Very true. It is not a thermal liner. And what a detailed description of the thermal liner . Don't you think the Tornado Pro is a better purchase compared to the Helios/ Helios Prime ?
You get so many added features with it as compared to the Helios, while both have Knox armors
-Thermal Liner (The one that you mentioned- Raw cotton-silk, etc)
-CE Approved Back Protectors (Your spine is much protected when compared to the Helios as it does not come with a CE Approved armor)
-Original Dupont Cordura Reinforment at Impact zones giving higher abrassion resisitance
-Mesh thickness is better

Helios: 7.8k
Helios Prime: 8.5k
Tornado Pro: 7.4k

So you end up paying more for having less features. Rynox imo (out of experience) has good after sales service as compared to Spartan (Here is why). Neither is Spartan a brand like and Alpinestar/ Dainese etc so why pay more ?

Just my opinion, which I felt may help make a wise choice.

True. I own a Spartan Helios, bought it two years ago. Lost my rain liner so called up support but he said only one word 'NO' and hung up while I was talking. Then few times they didn't even pick up. Horrible after sales support.

Today I ordered a Rynox Tornado Pro after trying on my friend's RTP. I hope Rynox's after sales support is better.
