The protagonist in this one wakes aboard the wreckage of the space-going equivalent of a 747 or the like. That is, it's a commuter spaceship of some sort. The ship has crash-landed on some unknown planet or planetoid with a very thin atmosphere and (IIRC) a rather unpleasant climate. It's very difficult for the protagonist, and he realizes immediately he needs to acquire some sort of environmental protection.
Survival being the first order of business, the protagonist acquires a "survival suit" from underneath one of the seats. I remember the suit being described as sort of a lightweight emergency suit in case of the ship having an explosive decompression event while in space. The protagonist comments that it wasn't nearly as effective as an actual space suit, but it would at least insulate him from the weather (can't remember if it is too cold, or too hot) and make breathing a little bit easier.
There's a bit of exploration of the planet around him, but IIRC, his efforts are limited until he finds an actual space suit. I think he locates the cockpit of the spacecraft, which (again, IIRC) was torn free from the rest of the vessel in the crash. However the space suit is found, it represents a turning point of sorts in his fortunes. With the atmospheric pressurization capabilities of a full space suit, he's able to engage in normal physical activity again. I believe it is at this time he removes the bodies of the other passengers from the vessel to give them a burial of sorts, and to keep his own shelter (the wreck of the ship) habitable.
I do not recall the ending of the story, other than I remember it being a happy one. There may be an element of Robinson Crusoe to the tale, with the protagonist discovering and befriend a native of the planet, which helps him survive until rescue. Or the rescue may have been more straightforward. I really can't remember for sure.
I'm almost positive I read this in an anthology, rather than a sci-fi magazine or periodical. I think the story is a rather old one. Certainly no later than the 1970s, and likely to be considerably older. I can't narrow it down beyond that, unfortunately.
