THE FORTIS LAYERING SYSTEM
Build warmth, weather protection and breathability for real-session carp fishing.
1. BASE LAYER
moisture control, odour, comfort
Your next-to-skin layer pulls sweat off the body to keep you dry and regulate temperature. It’s the foundation that prevents clamminess so every other layer works better.
2. INSULATION LAYER
heat retention, breathability, loft
This traps heat without bulky weight and still breathes when you’re active. Wear it over your base and under a shell to hold warmth through lulls and long sits.
3. PROTECTIVE LAYER
rain/wind protection, breathability, fit
Your outer shell blocks wind, rain, and spray while allowing moisture to escape. It’s the hard-wearing shield that keeps the whole system performing in real weather.
THE PRINCIPLES OF LAYERING
The Fortis Layering System helps carp anglers match base, insulation and protection for any session. From fast-moving stalking day sessions to static overnighters, use our collections, fabric tech and sizing tips to tune in the comfort you need without the bulk.
Good layering controls moisture next to skin, traps heat efficiently and blocks wind and rain—so you can cast, move and target your quarry in real weather conditions.
FAQ's
What is the Fortis layering system?
It’s a three-layer approach—Base, Insulation, and Protection—built for real carp sessions. Start with a moisture-moving Elements Base Layer Top, add Marine Liner or Trail Hoodie insulation for warmth, and finish with an Marine or Trail shell to block wind and rain.
Should I wear Tundra fleece under a Marine Jacket?
Yes. The Tundra Fleece provides the heat, while the Marine Jacket blocks weather. Pick a lighter Trail Hoodie or Trail Waterproof Jacket for mobile angling. Pick a heavier Tundra suite for colder sessions.
Trail vs Marine—what’s the difference?
Trail is a lighter, more affordable, packable shell ideal for active days and changeable showers. Marine is your maximum-protection outer—jacket and trousers—for prolonged rain, strong wind and exposed banks.
Do waterproof ratings and breathability really matter?
They do. Our membranes and DWR finishes keep rain out while allowing sweat to escape, so you don’t get wet from the inside when walking the bank, casting or pushing the barrow round the lake. At Fortis, breathability is our main priority!
How should I size for layering?
Choose a true-to-size base, a comfortable (not baggy) mid-layer, and ensure your shell fits over both without pulling at the shoulders or elbows. Check our size guide if you’re between sizes.
Care tips to keep performance high
Avoid fabric softeners on technical layers, wash as per the label, and periodically re-proof shells to refresh water beading. Brush off mud before washing for best results.
