Micro-Grid Fleece Sleeping Bag & Quilt Liner
Add 10 to 15°F to any bag or quilt without buying a new one. Soft micro-grid fleece at 17 oz, machine washable, and sewn in Pennsylvania. Trail tested, couch approved.
Not every night calls for a technical sleep system. The Micro-Grid Fleece Liner is JRB's everyday option — soft, warm, and simple. Layer it inside any JRB quilt or sleeping bag to add 10–15°F of warmth, or shake it out on its own as a fleece camping blanket when the full setup is more than you need. No backpacking price tag. No moisture-wicking claims. Just fleece that feels good and holds heat.
What makes it different
Most fleece liners are an afterthought — mass-produced overseas and sized for generic sleeping bags. The Micro-Grid is cut to fit JRB quilts specifically, so it layers cleanly without bunching or shifting. The micro-grid pattern adds loft and softness without the bulk of heavier polar fleece, and at 17 oz it packs down small enough to toss in a day bag without a second thought. Five colors, all sewn in Pennsylvania.
How to use it
- As a quilt liner: Layers inside any JRB quilt to drop the temperature rating 10–15°F — great for pushing a 3-season quilt into shoulder-season territory
- As a sleeping bag liner: Adds 10–15°F to any sleeping bag, extending your system into colder nights without buying a new bag
- As a standalone camping blanket: Warm enough on its own for mild nights at the campsite or around the fire
- At home: Soft enough for the couch. Washable enough to actually use it there. Trail Tested. Couch Approved.
