Learn about the 1P Cirriform DW
At the end of a long day, setting up your shelter should feel straightforward and sure - fast to pitch, solid in wind and rain, and dependable as the light fades.

Refined by Experience
Every curve, angle, and stitch of the Cirriform DW has been shaped by years of real trail use - by YAMA and by thru-hikers who've relied on it through wind, rain, and long miles. It's not about chasing the lowest weight; it's about making thoughtful choices that enhance performance, stability, and ease of use.

Durable, Lightweight Materials
The Cirriform DW is made from durable, recycled 20D Silpoly - a lightweight fabric chosen for its reliable performance in outdoor environments.

Silpoly absorbs less water than silnylon, reducing added weight, and lower sag ensures the tarp stays taut through the night.

Required items (not included):
The items needed to pitch your shelter will vary depending on your approach.
- Front Pole: About 44" - 45" (~111 - 114 cm) when pairing with the Bug Shelter or 39" - 42" (~99 - 107cm) when pairing with the Bivy
- Rear Pole: At least 31" (~79cm) when pairing with the Bug Shelter or at least 26" (~66cm) when pairing with the Bivy
- Stakes: 6 (8 for better wind stability)
- Rigging: If you plan to pitch the inner on its own (not under the Cirriform), you will need additional guyline or our Stand-alone rigging kit. If using tent poles or trekking poles without baskets, you may also need two of our guyline grommets (not needed with stand-alone kit).
Notes/FAQ:
- Do I need a groundsheet? A groundsheet is not required, but using one will help extend the life of any floor.
- 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.
Pitching
How to pitch
Start by staking out the corners of the tarp to establish your base. Raise the poles at the peaks and stake them to form the shelter's shape. Adjust and tension the lines evenly for a tight, balanced pitch. Once the outer is secure, attach the inner by clipping the corners and apexes to the tarp. When breaking camp, leave the inner and outer connected so your shelter is ready for a quick, seamless setup next time.

Baby bumps and bodyguards
Format: Kindle
Dark, emotional, and unexpectedly tender, Not Ready is an omegaverse romance that delivers found family feels, fierce protectiveness, and a very pregnant heroine who refuses to break. Vale’s on the run from a stalker, but lands in the arms of three private security alphas, cue the swoony tension, fake marriage twist, and slow-burn heat.
It’s a little gritty, a little soft, and a whole lot addictive. If you love protective alphas, high stakes, and heroines with quiet strength, this one’s a must-read.

Strong Omegaverse Comfort and a Attention Grabbing Plot
Format: Kindle
Jillian West never misses when it comes to Omegaverse, and Not Ready is no exception. This story was the perfect blend of cozy comfort and emotional depth while still delivering a strong plot.
Vale is such a powerful heroine, she is strong, capable, and determined but I love that she still allows her pack to love and take care of her. It’s that balance of independence and vulnerability that makes her so relatable.
The relationship dynamics were amazing: Bishop is steadfast and completely head over heels, Mercy is skeptical but protective in his own way, and Holt is the hesitant one whose slow fall is so satisfying to watch unfold.
The romance hits that sweet spot between insta-love and cautious build, keeping me hooked the entire way through. And that ending. Oh my god, the cliffhanger! I need the next book in this duet immediately.

Interesting
Format: Kindle
So I will say I enjoyed the story, for sure had its moments where it dragged but it was a great story. I really liked that omegas picked their alphas/make the pack. Normally the Alphas make it and the omega fits in with them which is great but I enjoyed this new version where all the power basically went to the omega. It was a nice change of pace. I can admit some of the weird bedroom stuff with her being pregnant was odd, it’s really not hard to do stuff when pregnant (I know I’ve had two and it’s normal and even encouraged at the end especially if you want the baby out). But I like the story as a whole and will read the second, I do hope the next one isn’t dragged bc it stopped being action or tense after she met her alphas and I don’t think it was brought up or properly done when they tried to do it. More sweet after she left.

I’m a little disappointed.
Format: Kindle
I usually like Jillian West’s books but this one was missing a lot for me. The pregnancy didn’t come across as real. She’s on her feet for 12 hour days but is perfectly healthy at 8 months pregnant? Yet the week she moves in all of a sudden she’s not? She is planning on actually running during one of the plot buildups. But at 8 months pregnant that’s incredibly hard to do. The lack of breathing ability and lung space, the change in body center, mass, and gravity. All of it prohibits running, unless you’re an athlete this didn’t come off as at all realistic.
I didn’t feel any connection with the alphas. There wasn’t any emotional connection. It could be because of the tense it was written in. But I didn’t get any deep feelings out of this. It came across as checking off boxes. Even the spicy scenes weren’t really believable for me. I wanted to see them fall for her, and it just kind of all fizzled. Even Bishop.
One thing I did really like was the ending. I did not see it coming and I’m interested in reading book two because of it. But on the whole this book was mostly disappointing for me.
