The new Kirra Castlerock builds on its proven predecessor and marks another step forward in our material development. For the first time, the Flysheet a siliconized fabric with PFAS-free C0 water repellency. The C0 treatment allows water to bead up and roll off without harmful fluorochemicals. The silicone coating on the outside ensures longer-lasting water repellency, while the PU coating on the inside guarantees complete waterproofing. At the same time, the silicone layer increases tear and tensile strength, thereby improving durability and cold resistance. The 2-person tent has a dark, understated appearance for a low-profile presence in nature. The 4-season version also features a neon red frame for better visibility in snow and emergency situations.

Steven ★★★★★ Aug 14, 2026

First time using a siliconized flysheet and the water just beads off instantly, even in that steady drizzle we had last weekend. The PFAS-free coating is a nice peace-of-mind bonus, though I'll have to see how it holds up over a few seasons.

Emily ★★★★★ Aug 13, 2026

The neon red really pops against the castlerock gray, and the PFAS-free coating held up through a full night of rain without a single drip inside. Set-up was quicker than I expected for a 4-season shelter, and the siliconized flysheet packs down smaller than my old tent.

Emily ★★★★★ Aug 12, 2026

The flysheet feels noticeably lighter and more supple than my old tent, and that silicone coating sheds water like nothing I've used before. I pitched it on a windy ridge and the neon red definitely makes it easy to spot from a distance.
