All you need is a rested buff, 1 hp food and 2 stamina + frost resistance potion.

Then just run up and recover your body. And do not stop. You can jump over rocks to avoid any chasing wolfs as you are much faster with no armor.
You could also take a portal materials up and place them on top of some rocks, grab your items, run back into portal and re-equip.

I realy hope you are not trying to recover your items at night tho.
