Even though I weigh considerably more than their upper limit on packed trails it's not a problem, and the dense, late-season snow off-trail only lets me sink about 4-5".

For everyone else, these snowshoes share the design features and performance of MSR's severe-terrain "Ascent" line, but in a lighter, simplified form that's perfect for established trails and day hiking both on and off trail in rolling terrain.
The first thing you notice is how the frames are made of notched aluminum bar instead of aluminum tubing.
