The baby brother of the Clip Flashlight, the Lightyear shares all the same features, but in a roomy 1 person size. It's been redesigned to have more usable interior space, a taller peak height, and more gear storage all without an increase in weight (and a lower MSRP). The single door, single vestibule, and all-mesh body make it the perfect minimalist shelter for those looking to travel light and fast.

    1. Rain/condensation a problem

      This tent is all good until it either rains or you have condensation in the morning. The zippers open directly over the mesh door so and moisture cascades through the mesh onto your head or sleeping bag. A better design would have been to have the zipper open onto from the side like the old model. So I'd give the tent itself a thumbs up but the fly an emphatic thumbs down. on Sep 4th 2017

    2. Held up well in massive storm

      I used the Light Year on a three night backpacking trip across Pictured Rocks, Michigan. On night two a massive storm, rain, wind, thunder, lightening hit. The storm lasted at least 8 hours. The tent held up so well! No rain/leakage at all.
      The good: Fairly easy to set up, tear down, lightweight, the light holder thing is really cool. The tent fits in the bottom extra pouch of my backpack so I am able keep it separate from the rest of my stuff. So if it's wet it won't wet the rest of my stuff.
      The ok: I can sit up (I'm 5'2") at the very front of the tent..very, very front. My backpack fits in the very, very front..which is great, but getting in and out of the tent while the backpack in the way is kind of difficult. I have room, to lay down and have my backpack at the very front. The vestibule worked ok. I left out my raincoat, cooking gear etc. I didn't leave anything that I was worried about getting wet.
      I would buy the tent again. I realize you have to give and take when you are looking at such a lightweight tent.

    3. Excellent One Person Tent

      I was debating whether to get a bivy sack or one person tent when I bought this. I'm very glad I went with the Light Year 1. It's light weight, easy to set up, and pretty spacious inside. It's got a few cool features like the multifunction vestibule, and Night Flow. Plus, all the materials are durable and well constructed. You'll have to be a bit careful with the mesh body fabric, but the breathabily is worth it. Overall, it's a great solution for someone looking to go minimal, yet still have some comfort features. on May 3rd 2017

    5. Cozy, durable, practical

      I just received the new Light Year as a gift, and took it on one-night solo trek last week in the Savage Gulf wilderness in TN. It was an exceptionally clear, starry night, with an overnight low of about 24F.

      The setup was very simple. Simply stake out and tension the corners, insert the poles in their respective grommets, then attach the clips. It is very easy to achieve a nice taught pitch thanks to the line-lok tensioners, which also make fine-tuning adjustments simple after the tent is up. I opted to set up the fly in the awning configuration which is very easy to do, and a feature that I really like. I'm glad that SD opted to use 68-70D nylon fabrics for the floor and fly, rather than some of the low-denier fabrics used in many UL tent designs, as this should make for a more durable tent over time.

      Width- and length-wise the tent feels very roomy for a 1P. The only drawback is that the shape of the tent doesn't quite allow one to sit upright in the tent when closed. When I initially set the tent up, I did zip the fly all the way down to survey the vestibule size, which had adequate space for my pack and boots. I do believe that the tent would have decent ventilation even with the fly zipped all the way closed despite the lack of any fly vents, as there is a nice gap between the fly and the ground all the way around.

      This tent is also great for stargazing on starry nights--with the door of the fly rolled up--as the mesh canopy is angled up and over your head.

      One thing to note is that SD includes only the bare minimum number of stakes needed to set up the tent and the fly (9 stakes required all together), though there are additional stake out points where the poles attach, in addition to two buyout points on either side of the fly. You should only need to stake out these additional points if you are camping in an area with sustained high winds, however. There were intermittent, strong gusts of wind throughout my first night in the tent, and I had no issues.

      Overall, I'm very pleased, and look forward to using this tent more and more. There was clearly a lot of thought and R&D put into this latest design, and I am satisfied with its pack weight and size (3.5 lbs on my scale with the footprint included).
