User Review: Sierra Designs Lightning 2
had the SD cliplight for eight years and loved it, so was eager to try out this roomier "lightweight" option. big disappointment.
the vestibule is terribly designed. in poor weather, you cannot zip back the vestibule to vent while cooking because it extends over the inner tent and rain pours in. you also cannot undo it halfway, because it flops inside (soaking wet) and won't reach its attachment point. vestibule doors need to clear the tent body while open.
the velcro attachments to the fly/poles are awkward, slow and dumb.
agree that this is NOT a tent for the high mountains. the fly sits high and WILL let weather in.
further, this is not really a lightweight tent. at five plus pounds, its quite heavy for what it offers.
i would place this tent in the mediocre middle, along with (i suspect) many of the other so-called light three season tents. for fairweather mellow backpacking, it's likely fine.
