Unlike the regular T-51b power armor found in Fort Constantine, the winterized version lacks rust, features a snow-camouflaged paint job with US livery, and has 45 damage resistance as opposed to the regular version's 50.
The armor is fitted with a back-mounted TX-28 MicroFusion Pack which generates an output power of 60,000 Watts to power the HiFlo hydraulic systems built into the frame of the suit. Made of a poly-laminate composite, the outer shell of the T-51b is lightweight and capable of absorbing over 2500 Joules of kinetic impact. The 10-micron-thick silver ablative coating can reflect laser and other radiation emissions without damage to the composite subsurface, and the eyeslit for the helmet is made of bulletproof glass to protect the wearer from any projectiles.
The armor has a US Army logo and flag decal below the valve on the back. It also has 2 stars on the front of the shoulder plates, and has the serial code DiV:5128417 USA Army on the left side of its breast plate.
The winterized T-51b is not available to the Lone Wanderer during the simulation. They get it after finishing the add-on.
There is no need to receive the Power Armor Training perk before obtaining the suit as once the quest is finished by opening the VSS armory, the perk is automatically granted.
The armor outside the simulation has a slightly darker color and has black gloves instead of yellow.
The armor has an extremely high damage resistance and an extremely low degrade rate.
The picture of the helmet when in the inventory is just the picture used for the armor instead of one of the actual helmet, whether this is a glitch or just input by developers is unknown.
Even though the new U.S. flag is already seen on the flagpoles in the army camps, the back of the racked T-51b armors still shows the old US flag.
pcps3xbox360 The version given after completing the Anchorage Reclamation simulation is the "sim" version, rather than the intended "wasteland" version. Among other issues, the "sim" version has abnormally high health—close to 10 million hit points—and as a result will never become noticeably damaged. The armor can only be repaired by merchants.

pcps3xbox360 Taking this armor while doing the quest You Gotta Shoot 'Em in the Head (the helmet excluded) the game confuses this for the T-51b power armor from Fort Constantine and completes the mission. This also rewards with the achievement or trophy respectively. Mr. Crowley will no longer speak to you after getting the armor, other than the remark about stealing what was rightfully his. One way to avoid this is to keep the winterized version in storage (e.g. in the locker in the Megaton house or Tenpenny Tower suite) while completing the quest, or hand over the keys and beat Crowley to the armor.

xbox360 Sometimes, when equipping the power armor (the helmet has not been confirmed) the power armor will appear invisible, leaving only the arms visible, but it will still have the 45 DR of the suit. Un-equipping and then re-equipping the power armor can fix this. [verified]
ps3 When the power helmet is equipped and chinese stealth armor is worn, your body may become entirely invisible (do not mistake for chinese stealth'invisibility powers") and your helmet will look like it is floating yet you can still move and fight. To fix this take off the helmet and your character will be fixed. [verified]
