Sibley Fly Canvas 400 Sand

The All Season Fly’s are manufactured from Tentex® PC39. The fabric is made from ring-spun yarn, woven in a very dense twill weave (duck woven) and is extremely strong and durable due to the applied coating, while remaining very comfortable in all weather conditions and throughout all seasons. Suitable for intensive / professional use.

The All Season Fly’s are treated with a German-made, oil-based coating to be UV resistant, fade resistant, water repellent, fire-resistant, and mould and rot resistant while maintaining breathability. What you don't see does make a difference: the coating is incorporated deep into the fibres before production, which significantly extends the life and performance of the canvas, without losing its breathability. The Fly’s are also fire-retardant according to CPAI-84

Double Roof Protection - Acts as a protective second roof for your Sibley Bell Tent, keeping rain, snow, dirt, bird droppings, and falling leaves off the canvas while still allowing your tent to breathe. Essential when camping under trees.

Designed for intensive and professional use - The All Season Fly is where premium craftsmanship meets high-end functionality: a rugged all-season double roof protecting your tents against all elements. 

Extends the lifespan of your tent and keeps it looking like new.

Insulating Properties - Creates a dead-air space between the canvas and the fly, helping regulate temperature inside your tent. Keeps it cooler in hot sun and reduces heat loss in cold conditions — ideal for extreme climates.

UV Protection - Blocks up to 95% of harmful UV rays, preventing sun damage and slowing down the natural erosion of your canvas’s protective treatments. 

Standalone Shelter Option - Can be pitched on its own as a bell-tent-shaped shade or rain shelter. Use a compatible Sibley pole set and extra stakes, or repurpose your existing Sibley hardware for a lightweight lounge setup.

Washable & Retreatable - Easy to clean and re-treated with our CanvasCare maintenance products, ensuring long-term performance.

Wood-Burning Stove: 

This type of double roof is suitable for use with a wood-burning stove.
