Keep your lower back supported and comfortable in the air, at your desk or behind the wheel. The Sea To Summit Aeros Premium Lumbar Support Pillow uses the same technology and design aesthetics from the popular Aeros backcountry packable pillow range. Luxurious, lightweight and compact, it features a super-soft brushed 50D polyester-knit exterior and a silent, contoured TPU air bladder for support and comfort. Inflate easily with a couple of breaths and fine-tune your level of support with the user-friendly, low profile multi-function valve. The lightweight and breathable fabrics keep weight to a minimum, and the whole pillow packs into an elegant EVA case at the end of your journey or day at the office
