If anyone thinks this warrant's it's own thread, that works, but here's a bit of a comparison between the two shirts.
CP Gear OTW
ICE DA
Both shirts similar, CP Gear uses DriFIRE material for the torso, ICE is a High Performance FR Polyester (not sure of name brand). Both use authentic CadPat.
Collar:
OTW
DA
Not much difference on the two collars, though you can notice that the DA's zipper goes a little lower, and has a dummy cord loop on the zipper. The collar on the OTW is snugger to the neck when completely closed.
Cuffs:
OTW
DA
Once again, not a huge difference, the velrco tabs are different, but nothing big.
Sleeve Pockets:
OTW
DA
Here's a little bit of difference. Velcro patch on the OTW is a lot bigger than on the DA shirt, although the DA shirt isn't lacking.
As far as the pockets, I find the DA's easier to get into because of A)the dummy cord loop, and B) the opening has less of a pleat covering the zipper, making access easier, and allowing a little more opening.
No big difference in carrying capacity between the two (you shouldn't be jamming too much stuff in there anyway).
Now, here are some features that are only found in the ICE DA shirt;
Reinforced elbows have Velcro closed slots for foam pads:
Pen slots on both sleeves (2 per):
Once again, these haven't been worn overseas yet (getting packed into my AB right now), and these are initial impressions from trying out and wearing with my full battle-rattle.
Both shirts wear very comfortably (OTW a little more comfortable out of the bag due to the driFIRE material, but not noticeably more than the DA shirt after some wear) under Body Armour.
I like that the DA shirt has dummy cord loops on all zippers (an obviously easy do-it-yourself fix you can perform on the OTW).
Price difference between the two is about 30$ Can. I'm not going to tout either over the other, but as I said, for the price, and the extra little features, I personally lean towards the ICE DA shirt. (I will wear both)
