There’s more to warmth than stuffing a jacket full of insulation. Fishing demands comfort while active and while still. The right insulation keeps heat in without overwhelming you when rigs need tying or a fish suddenly changes your plan.
Warmth comes from breathability
A jacket that traps too much heat makes you sweat. That moisture cools your body and steals warmth fast once you slow down. Breathable insulation lets excess heat escape so you stay comfortable for the entire session.
Primaloft®: Lightweight warmth for mobile anglers
Originally developed for the US military, Primaloft® balances heat, packability and breathability better than traditional insulation. It traps warmth efficiently without bulk so you can stalk edges, climb banks and move freely.
- ✅ Warm even when compressed or wet
- ✅ Breathable to reduce mid-session chills
- ✅ Lightweight for all-day comfort
Snugpak Softie®: Proven performance for extreme cold
Softie® insulation is designed for brutal temperatures and known for its dependable loft and heat retention. If you fish long, cold nights or winter campaigns, Softie® keeps your core stable even as conditions deteriorate.
- ✅ Serious insulation for bitter nights
- ✅ Retains heat even under sustained moisture
- ✅ Trusted by forces and expedition users
Down vs Synthetic?
Down is warm but struggles when wet. Synthetics like Primaloft® and Softie® keep working through damp weather and high humidity — ideal for UK carp sessions.
Fit matters just as much
If movement feels restricted, you stop moving. Less movement means less heat. Pick a cut designed for angling positions: kneeling, casting, netting and waiting.
Layer smart
An insulated jacket should work as part of a system. A breathable waterproof over the top and a good base beneath keeps heat balanced.
