Pardon my French but how in the ham sandwich can a jacket insulated with air keep you warm in cold weather?
I'm curious to see if they actually work.... might just make and expensive camp pillow.Quote:

It says it has insulation, the amount of air just determines the loft of said insulation. I'm kinda curious as it is like an inflatable sleeping pad...if you don't inflate it properly and all the way it has less insulating capacity.Quote:

No actual temp ratings. I am skeptical.Quote:
AS WARM AS YOU WANT TO BE
5 pumps give you an initial blast of insulation that will suffice for normal activity on slightly chilly days.
10 pumps will get you started in harsher conditions.
15-20+ pumps will protect you in the cruelest of colds, like when you’re on the lift waiting to take that extra end-of-the-day run.
NOTE: Pump calculations are baseline references using a medium-sized garment. Personal preference and garment size will result in a variation of the number of pumps required.
What's a chilly day?
What are harsher conditions?
What is cruel cold?
Its effectiveness would be very modest, due to internal air convection. That's why an inflatable pad with no internal down (or other air-movement-restrictions) has a very modest R value (like R=2.0 for a 2" thick inflatable air pad) vs. R7 or so with an inflatable pad of same thickness with internal down.Quote:

Well since I have no experience with this product I can't recommend it however if you're interested in trying out this type of product/technology the cheapest point of entry I could find was a 460.00 vest (green/size small) on Amazon

Sorry meant $60.00 vestQuote:

They might make a nice super-light life jacket?
As for adjustable warmth, that's what zippers are for.
I'm wondering if it comes with a repair kit?:eek:
Go ahead and fill with helium...definitely lighten up your load...

A gimmicky solution to a nonexistent problem.
That’s what the Michelin hikes in.
