MSR has introduced the Snow/Sand Stakes in two sizes, along with a hammer. The tent’s guylines are attached to the notch on the wide, spade-like portion of the stake, allowing it to stay fast in loose mediums like snow and sand.

That’s a great hammer by the way. Extremely lite; especially compared to the snow peak hammer i had before this MSR one. Not that anyone asked for my review.
