Thermarest Lumbar Pillow

Long drives, overnight flights, and hard canoe seats all share one thing in common, and the Therm-a-Rest Lumbar Pillow addresses it with the same pressure-mapping thinking that goes into their sleeping pad lineup.

The die-cut foam construction removes material down the centre of the pillow to reduce pressure along the spine, while maintaining density along the sides for lateral support. It's a deliberate design based on actual pressure mapping data rather than a generic foam rectangle, and the difference is noticeable on extended sits. The self-inflating core means you can dial in firmness with one hand, adding or releasing air until the support level suits you, whether that's a firm brace for a long paddle or something softer for a road trip seat.

At 3.6 oz and packing down to 4 x 7 inches, it slips easily into a day bag, canoe pack, or carry-on without taking up meaningful space.
