    I didn’t want to toss my old REI Half Dome, so finding this rainfly was a lifesaver. Fit was spot-on.

  2. Katherine Nelson (verified owner) –

    Weather turned rough on our trip, but this rainfly held up great. Probably the best tent rainfly for backpacking I’ve used.

  3. Melissa Phelps (verified owner) –

    Solid upgrade for a worn-out fly. Easy to pack, feels light, and works great with my old tent setup. Highly recommend buying if your original went missing.
