Description
The 1P Cirriform SW
When you arrive in camp after a long day, a shelter you don't have to think about makes a difference. The Cirriform SW is built around that. The floor, mesh, and fly are one integrated piece. No inner to clip in or adjust. Just pitch the fly, and you're done.
The SW is back!
The Cirriform SW has been a long time coming. We made an earlier version in Dyneema® composite fabric, and it was one of our favorite shelters we've ever offered. The original design wasn't compatible with silpoly, so when we phased out DCF, the SW got shelved. We're excited to reintroduce the SW with our new silpoly design. It's the same shelter at heart: one integrated piece, simple to pitch, more spacious than the DW.
Dual Entry
The Cirriform has two ways in, and each serves a different purpose. The side entry is the everyday option, easy to get in and out whenever you need to. The front entry is there for when weather moves in, keeping the sleeping area covered while you come and go. Switching between them is as simple as moving a clip.
Two builds, same shelter
The Cirriform SW comes in two builds. The Standard uses a heavier-coated fly (~8000mm HH), 0.6 oz mesh, and a Sil/PU floor (~4000 HH) for better puncture resistance. The Light uses a standard-coated fly (~1800mm HH), a recycled Sil/Sil floor (~2000mm), and 0.5 oz mesh for a lower packaged weight. The only visible difference is the floor color: black for Standard, brown for Light.
Notes/FAQ:
- What about condensation? Condensation can happen with any shelter. Sometimes it's unavoidable, but single-wall shelters are inherently more prone to condensation than double-wall shelters. Two things are going on: without a buffer between you and the fly, the relative humidity of the air in contact with the inside of the fly tends to be slightly higher, which increases the chance of condensation forming. That same lack of buffer also increases the likelihood of inadvertently contacting a wet wall (think of the DW as having an early warning system). The good news is that the Cirriform provides enough vertical distance under the fly that you're unlikely to bump into a wet wall from simply tossing and turning in your sleep, unlike many mid-style or side-entry single-wall shelters. It's also easier to manage condensation with a chamois cloth since you have direct access and can easily wipe down a wet wall. For more tips, see our condensation page.
- What conditions is the SW best suited for? We recommend the SW for three-season type of use. It handles rain and wind well, but we don't recommend pitching it on significantly accumulated snow (a few inches should be fine). The problem with pitching on snow is that if the floor sinks into the snow under your weight, it will pull on the rain fly and risk damage - it ain't no hammock.
- Do I need a groundsheet? Not required. The floor is durable enough that most hikers skip it, but using one on rough ground will extend the floor's life.
- Do I need to seal the seams? Tarp seams should be sealed using a sealer for silicone coated fabrics (we recommend Seam Grip +SIL by Gear Aid). Optional seam sealing service available. Floor seams are factory-taped and don't require sealing.
Fly made in Vietnam. Floor and mesh assembled in Montana.

Pitching
How to pitch
Stake out the corners of the tarp first. Raise the poles at the peaks and stake them out. Tension the lines evenly for a taut pitch. The mesh and floor are built in, so once the fly is set, you're done. It packs and pitches as a single unit.
When zipping up the shelter, THE FLY CLOSED FIRST, then zip the netting to avoid undue stress on the netting zipper.
To open the zipper from the inside, pull the yellow cord to avoid needing to reach into the corner.
The videos below show how to pitch the Tarp and the DW. The pitching process is essentially the same, except you don't have to clip in or adjust the inner.

Comfortable Ergonomic Chair for Long Workdays
Color: Black, Color: Black
I’ve been using this chair for my home office, and it’s been a great addition to my workspace. The seat cushion is thick and comfortable, even after several hours of sitting, and the mesh back keeps good airflow throughout the day. I especially like the adjustable headrest, which provides extra neck support when leaning back during breaks. Assembly was straightforward, the chair feels sturdy, and the wheels roll smoothly on my floor. The all-black design also gives it a professional look that fits well in any office setup. Overall, it’s a comfortable and affordable ergonomic chair that offers excellent value for the price.

Sturdy but uncomfortable
Color: Black
The seat itself is sturdy and easy to put together, I’ve now had the product for 8 months and had no issues wear/tear despite nearly daily use, but… it’s not comfy, at all. The seat cushion has a texture to it that scrapes at my legs if I don’t have an extra pillow on it or am wearing shorts. Additionally, the seat pillow is just kind of hard. It doesn’t give very much at all, so if I sit on it for more than an hour or two at a time my butt starts to get really sore. It works as a budget option, but invest in a good seat pillow if you plan to sit in it for any length of time.

A chair that does the job
Color: Black, Color: Black
I’m really happy with this chair overall. I wanted something comfortable, sturdy, breathable, and spacious enough for long hours at my desk when I work from home, and this chair delivered. I’d easily give this chair five stars because it exceeded my expectations in comfort, quality, and overall value.
Comfort and Support
The mesh back keeps it cool and comfortable during extended use. One of my favorite features is the adjustable lumbar support. You can manually position it exactly where your lower back needs support, and it fits the curve of my back perfectly. It provides great support without feeling too firm or uncomfortable.
Build Quality and Design
The chair itself feels solid and well-built. It doesn’t creak or make noise when shifting around, which makes it feel stable and high-quality. The seat is roomy and comfortable, and the overall design looks clean and modern.
Easy Assembly
It also came with an instruction manual that was extremely simple to follow, and assembly was very easy. I was able to put the chair together by myself in about 20 minutes without any help.
Armrest Functionality
I also like the armrests. They aren’t adjustable by height, but they do flip all the way up, which is surprisingly convenient. You can easily slide the chair under a desk or use it as an armless chair when needed.
Packaging and Presentation
Another thing worth mentioning is the packaging. Everything arrived extremely well-packed. Every individual part of the chair was wrapped securely, including bubble wrap protection for the components. The hardware and accessories were neatly organized, and the chair even came with the necessary tools for assembly in case you don’t own a drill or tool set. The presentation and packaging were excellent and showed real attention to detail.
Overall Impression
Overall, this is a fantastic office chair for the price: comfortable, supportive, sturdy, easy to assemble, and packaged exceptionally well. I’d absolutely recommend it and would confidently give it a five-star rating.

Very Straightforward and Easy to Use
Reload type: One Time Reload
I have used this several times, and it has always been a smooth and convenient experience.
The biggest advantage is how intuitive the process is. Reloading the balance is simple, quick, and easy to understand without unnecessary steps or confusion.
It is especially useful for managing spending, setting a shopping budget, or keeping funds ready for future purchases. Instead of entering payment details every time, having balance available makes checkout faster and more convenient.
I also appreciate how quickly the funds are applied, allowing immediate use once the reload is completed.
This is one of those simple Amazon features that works exactly the way it should.
Overall, easy, efficient, and user-friendly. I have been very satisfied with it. Five stars.

Easy and simple: Exact Step-by-Step Guide to Reloading Your Balance

I found reloading my Amazon gift card balance much easier than expected. The process was simple and took about 5 minutes at most. Here are the exact steps to do it:
Login: In the Amazon app or on Amazon.com, log in to your account.
Menu: Tap the 3 lines on the bottom right corner of your screen (next to Rufus, Amazon's AI).
Find Category: In the section highlighted "Shop by category," tap on Gifting & Registry (3rd option down in that section) and a drop-down menu will appear.
Select Gift Cards: On the drop-down menu, tap Gift Cards (first option).
Choose Your Action: "The Gift Card Shop" will appear. There you will have three options: "Redeem a gift card," "View your balance," and "Reload."
Start Reload: To add funds, tap Reload.
Select Type: Scroll down to "Add funds directly to your Amazon Gift Card balance" and tap which reload type you want (one-time, low balance auto-reload, or scheduled auto-reload).
Enter Amount: Choose your reload amount. The default is $25, but you can type in your own amount as well (the minimum amount is $5.00).
Finish: Tap the orange "Buy Now" tab.
***I used the Amazon app using the u i OneUI version 8.0 these Amazon app on Android version 16 (Baklava) on a Samsung Galaxy S25 Ultra. Others may have a slight variation of the menu setup on the Amazon app.***
