The new Backdoor 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 4-person family tent features a dark, understated design 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.

Zoe ★★★★★ Aug 14, 2026

Took this out in a heavy downpour last weekend and the siliconized flysheet shed water like nothing I've seen before. The PFAS-free C0 treatment held up perfectly, no beading issues at all. Honestly impressed for a four-season tent.

Stella Y. ★★★★★ Aug 13, 2026

The flysheet feels noticeably lighter and crisper than my old tent's, and the neon red actually pops beautifully against snow. Set it up in a gusty alpine pass and the siliconized fabric shed moisture like nothing I've used before.

Harper ★★★★★ Aug 11, 2026

The siliconized flysheet feels noticeably tougher than my old tent's, and the neon red makes it stupidly easy to spot at dusk. Set it up in gusty weather last weekend and the 4-season build held rock-solid all night.
