I had both a cirriform min (long) in silpoly and the splitwing. I sold the Cirriform. The splitwing is the best shaped tarp out there (for me...) Here's why
- I'm 6'4" and sleep on my stomach. I'm basically 7ft long once I'm in a sleeping bag. The splitwing and cirriform both handled this okay. BUT...
- I can sit up in the splitwing. Because the height is flexible due to the front wings I pitch it with a 49" trekking pole at the front and still have enough side coverage to not worry about wind blown rain. The cirriform design does not allow me to sit up in it unless I pitch it about 8-10" off the ground.
- Splitwing 10D sil/sil fabric is magical. It dries really fast (I once dried it out in 5 minutes during a 10mph breeze on a summit by holding the front wings and flying it like a kite), doesn't need to be seam sealed, and packs to the size of an apple. The 30D reinforcements are superbly designed and make a huge difference.
- Splitwing design goes up fast. I always pack it so the back end goes in last to the bag. Regardless of whether it's super windy or rainy I can get it up in 90 seconds. Shake out the back of the tarp, leave the rest in the bag. Stake the back two corners, wrap the rear middle line around my trekking pole and stake it out so the back wall is vertical. I also put the tip of the rear trekking pole through a loop on the rear middle stakeout point. Then pull the rest of it out of the bag while walking forward, jam the front pole in, pull out the front lines and stake them. Pull the two front corners taut and you're done. I set it up in a hailstorm right below Mather pass on the PCT in 90 seconds. Tossed my stuff inside and I was dry while the other hikers cuddled a boulder trying to stay dry getting pounded by pea gravel sized hail.
- Splitwing with Paria 1.3mm guylines and Lawson line on the front/rear apex is 250g in stuff sack. The vestibule is 60g extra but I rigged my ULA rain skirt to be a vestibule and it works great. With an extra extra long Borah DCF bivy (147g) I'm at ~400g for a (tiny!) double wall shelter. The cirriform I had was 375g.
- The cirriform with side entry sounds great, because that's my biggest complaint about A-frame type tarps, but in reality that side entry point zipper is under a lot of tension and it seems like a bad idea to really cinch that down. With the splitwing I put insane amounts of tension on my guyline stakeouts and never worry about it. The cirriform entry point also needs to be switched from one loop to the other to shift from side to front entry which is difficult to do with it under tension.
- Splitwing stakeout points are perfect. Due to having 4 along each side, plus a fifth midway up the side of the a-frame, you can stake out the splitwing to handle any weather. And due to the closed foot, I'm never worried about wind blown rain. I typically carry 6 ruta locura carbon fiber stakes and 6 8.5" lawson titanium skewers. That combo allows for pitching in any type of terrain really well. I used the Splitwing plus ULA rainskirt along a 500 mile section hike this year on the PCT (Sierras) mid July to mid August. It rained every day for half those days (monsoon season baby!) and I was really happy with my choice. I was going to use an 8x6 custom built poncho tarp but believe it or not the weight difference is about 100g between the poncho tarp and the splitwing plus dedicated rainjacket and rainskirt. That 10d sil nylon fabric in the splitwing really is incredible. I've also used the splitwing for about 9 months prior to that section hike. It's been durable. Now there are some downsides with the splitwing.
- I could totally cook in the pitched tarp, and did numerous times, but not with anything setup. I'd usually pitch the tarp, toss my stuff in, cook dinner, then setup my bivy and bag. It's not super spacious when you're sitting up. During one driving rainstorm that dumped a half inch overnight the dry area was almost exactly the size of my bivy. It will keep you dry, and your backpack, but not much else.
- There's no way it's a two person shelter, unless you're not expecting any wind, you're both short, and you're really good friends/partners who sleep on their backs. It's wide enough at the front, but the rear is a fixed 36" wide. As a one person shelter it's great.
- I wish it were about 6" longer and 6" wider at the rear. Probably because I'm 6'4" as mentioned.
- I'd love it if it wasn't front entry, but that's the tradeoff. I generally get into bed and never get out until the morning. So twice a day I wish it was different but I practice yoga, I'm nice and flexible. I've never tested the mesh interior, but the attachment points for it are well thought out and it's probably a nice inner if you're shorter. The vestibule I think is well worth the money but you can rig something out of your rain skirt like I did, or even just a jacket if you're not needing absolute 360 degree protection. It's also a lot less of an issue if you're shorter since you can burrow down towards the closed foot more. It's silnylon so it does stretch a little while wet. But it's never been enough for me to adjust the pitch to compensate. I just stretch it tight when pitching and it does fine.
