The tubes are small and don't cover a large surface area. It would be enough just to keep my body temp from going too hot. As parts come in and things get put together I will post updates, etc. Excited to get this working

Slight change of plans.
Going to make a shirt out of sport mesh rather then risk ruining my Under Armour shirt.
I have lots left over from my ghillie build, plus it will be much cooler being mesh.

Picked up some packing foam sheets and an emergency blanket. Going to use some left over OD green fabric from my gillie build and make an insulated pouch for the bladder to keep more cold in and my body heat and outside heat, well, out.

also FYI you don't need to run a whole suit of cooling, the more surface area you try to cover, the faster it will lose effectiveness. You really just need to run it up and down your spine for the best effect!
Also, insulate everything possible, tubes and pumps, and also lightly insulate the tubes near your skin since (depending on your mix) they might be able to freeze your skin.

I would even say upper back and neck is sufficient.

^ Good idea.

This cooling system will definitely come in handy when going toe to toe against intergalactic thermal-visioned hunters.

The beauty of running the front and back on separate pumps is that they will be wired with their own switches. I can run them both or just the back or front depending on weather and how I am feeling body heat wise.

Great idea bud, used these during fire fighter training. Slightly different setup, but dead useful. I stress caution on rapid body cooling, its as real a risk as heat exhaustion.

Didn't realize they were $300+. I saw this one from Fly Racing (they make MX gear) for $40.

You can prob find it from revzilla or Canadas Motorcycle or something similar (I'm sure there's like 3 or 4 different companies that make something like this)

EDIT: Apparently Fieldsheer makes one as well called the Iceberg Vest, and I'm sure Icon and them have something as well.

The ones you mention are evaporation vests. Those dont use active cooling like I am building.

I see, yeah they are evaporation vests that rely on latent heat of evaporation as opposed to what you're doing which is what I'd equate to being like a computer heat sink/Water cooling loop.

Bingo!

Pumps showed up and I forgot my hose and attachments at home (Currently at the cottage). Tested them out just in the sink and they throw quite a bit of water

I need to get them connected to the hose to make sure they have enough power to push the water through 6-7 feet of hose each (pumps are rated for 2 meters of lift).

Update:

Cooling system is complete to run. Still need to make an insulated pouch and tube housing.
Worked great! At first the sensation was like someone was pouring cold water down my front and back.

Switch on front my chest rig to turn on/off the 2 pumps.

Pump and battery housing on back of Water bladder pack.

Return water tubes to bladder.

Front of cooling shirt (Inside out to show tubes).

Back of cooling shirt (Inside out to show tubes).

Water Supply tubes in and out of shirt.

Quick connectors I will be using.

Material to make insulated pouch and tube covering (Foam, emergency blanket and left over material from my ghillie build.)
