At Gerry’s Fishing, we highly recommend the Sonik Bank-Tek Thermal Bed Cover as one of the most versatile additions to your sleep system. Whether you need an extra layer of insulation for mid-winter sessions or a lightweight, waterproof “summer blanket” for sleeping under the stars, this cover delivers. Constructed from Sonik’s high-performance Cloudbase+™ fabric, it offers an impressive 16,000mm hydrostatic head (HH), ensuring your bedchair remains completely dry even if you’re sleeping in an open-fronted shelter or under the stars during a heavy dew.
The cover is lined with soft micro-fleece and filled with silicone-treated hollow fibre, providing instant warmth and comfort. One of its standout tactical features is the integrated fold-out mosquito head net, which provides 360-degree protection from insects during those calm, warm summer nights without needing to zip yourself into a heavy bivvy.
The Bank-Tek Thermal Cover is built for high-spec weather protection and thermal efficiency:
| Feature | Specification |
| Model | Sonik Bank-Tek Thermal Bed Cover (EC0044) |
| Assembled Dimensions | L 205cm x W 115cm |
| Packed Dimensions | L 52cm x D 26cm |
| Weight | 1.95 kg |
| Outer Fabric | Cloudbase+™ (16,000mm Hydrostatic Head) |
| Lining | Micro-Fleece |
| Fill | Silicone-Treated Hollow Fibre |
| Connection | 4-Point Bed Attachment System |
16,000mm Cloudbase+™ Outer: This fabric is “ultra-waterproof,” providing a level of moisture protection usually reserved for high-end bivvies. It effectively shields your sleeping bag from condensation and rain.
Micro-Fleece & Hollow Fibre Filling: The thin layer of high-loft insulation adds approximately “one season” of warmth to your existing sleeping bag, making it a vital component for extending your fishing into the coldest months.
Integrated Mosquito Head Net: A wide, fold-out mesh panel that deploys quickly to protect your face and neck from bugs. This is a game-changer for summer “sanity” when the midges are out.
Universal Generous Sizing: At 115cm wide, it is designed to fit both Standard and Wide bedchairs comfortably, ensuring full coverage and eliminating cold drafts.
Four Bed Connection Points: The cover features specialized attachment points to secure it to your bedchair frame. This prevents the cover from sliding off in the night, even if you are a “restless” sleeper.
Silicone-Treated Fill: The hollow fibre insulation is treated with silicone to ensure it maintains its loft and thermal properties even after repeated compression in its stuff sack.
The “Summer Only” Solution: In the height of summer, this cover can replace a bulky sleeping bag entirely. Its micro-fleece lining feels great against the skin, while the waterproof outer keeps you protected from the morning damp.
Condensation Shield: If you fish in a small bivvy or brolly system, condensation can often dampen the foot of your sleeping bag. This cover acts as a sacrificial, waterproof barrier, keeping your primary bag bone-dry.
Lightweight Transport: At just under 2kg and with a compact packed size, it adds negligible weight to your barrow but significant comfort to your session.
Gerry’s Pro Tip: To get the best night’s sleep in summer, use the 4-point connection system on just one side of your bed. This allows you to use the cover like a traditional duvet, making it easy to “kick off” if you get too warm, while the mosquito net stays perfectly positioned over your head
