There are lighter pyramid shelters available for summer use, but if stormworthiness is important to you, take a look at a silnylon Mountain Laurel Designs Supermid Shelter. We’re happy to see the Supermid resist the urge to use lighter silnylon fabrics – the 20d silnylon used in it can be tensioned very high, and that makes it a good shelter in high winds and heavy snows. Lots of exterior guyline tieout points as well. One of our top picks for winter camping.
