, this heated liner helps create a more comfortable sleep and relaxation experience in cold conditions.
With a generous
198 × 66 cm (78.0 × 26.0 in)
size, soft cotton flannel front, durable Oxford fabric backing, and
250g/m² shaped hollow cotton insulation
, it can be used in multiple ways—as a heated sleeping bag liner, blanket, sleeping mat, or standalone layer.

5V/2A or 9V/2A power sources
, including suitable power banks, phone chargers, and emergency power supplies, giving you a convenient way to bring warmth beyond the campsite.
Targeted Heat Where You Need It
The CAMPCOZY 250 features
three built-in heating elements
positioned to provide warmth across key areas of the body.
The heating coverage is designed around the:
Shoulders
Back
Buttocks
Feet
This broad heating layout helps distribute warmth across multiple contact areas rather than concentrating heat in just one spot.
Whether you're resting in a tent, relaxing in an RV, or using the liner inside a sleeping bag, you can add an extra layer of warmth when temperatures drop.
Important:
Always follow the product's operating instructions and use a compatible USB power source. Do not leave a heated product unattended while powered on.
USB-Powered Heating for Flexible Use
You don't need a dedicated power station to use the heating function.
The CAMPCOZY 250 supports
5V/2A and 9V/2A USB power
, making it compatible with suitable portable power sources such as:
USB power banks
Compatible phone chargers
Emergency jump starters with USB output
Other compatible USB power supplies
This makes it easier to bring personal warmth to the campsite, RV, car, or home.
Portable power in. Comfortable warmth out.
Heating performance depends on the connected power source, ambient temperature, insulation, and usage conditions.
More Than a Sleeping Bag Liner
A sleeping bag liner is only one way to use the CAMPCOZY 250.
Its large rectangular design allows it to function as a:
Heated Sleeping Bag Liner
Add a layer of warmth inside a compatible sleeping bag during colder camping trips.
Heated Blanket
Open it flat and use it as a blanket while relaxing at camp, in an RV, or at home.
Heated Sleeping Mat
Place it on a compatible camp bed or sleeping surface for an additional insulated and heated layer.
Standalone Resting Mat
With the heating turned off, it can be used as a comfortable insulated mat during milder conditions.
One product. Multiple ways to stay comfortable.
Large 198 × 66 cm / 78.0 × 26.0 in Design
The generous dimensions provide plenty of coverage for sleeping or relaxing.
The wide
66 cm (26.0 in)
profile allows room to move and change sleeping positions, while the
198 cm (78.0 in)
length provides full-body coverage for many adult users.
Use it inside a sleeping bag, on a camp bed, or opened flat as a blanket or mat.
Soft Cotton Flannel on Top
The front side features
cotton flannel
, providing a soft, comfortable surface for direct contact with the body.
The cotton material is designed to balance comfort and breathability, making it suitable for extended use in camping, travel, and home environments.
Durable Oxford Fabric on the Back
The reverse side uses lightweight
90g/m² yarn-dyed Oxford fabric
, providing a durable and moisture-resistant backing for outdoor use.
It helps protect the liner when placed on camping beds, seats, or other outdoor surfaces while keeping the overall design relatively lightweight.
250g/m² Shaped Hollow Cotton Insulation
The CAMPCOZY 250 combines its heating system with
250g/m² shaped hollow cotton filling
.
The filling provides an additional insulation layer, while
parallel quilting
helps keep the insulation distributed across the product and reduces shifting during use.
This combination allows the liner to provide comfort even when the heating function is switched off.
Comfortable in More Than One Season
The CAMPCOZY 250 isn't limited to winter.
Cold Weather
Use the USB heating function to add targeted warmth when temperatures drop.
Spring & Fall
Turn off the heating function and use it as a breathable insulated mat or blanket.

Heat when you want it. A comfortable mat when you don't.
