Rockville entrepreneurs Tiffany and Chris McCasland, co-founders of The Chair Blanket, are scheduled to appear on Shark Tank on March 4 at 10pm on ABC. The couple will pitch their outdoor lifestyle product, which launched in fall 2024 and features a dual-sided design with a waterproof exterior and fleece lining intended to keep outdoor chairs dry and users warm.

After a night of snow flurries, the water-resistant coating shed moisture with just a quick shake. It's big enough to share but light enough to pack down small for car camping or tailgates. I even used it inside my tent as an extra thermal layer over my sleeping bag, and it noticeably boosted warmth. After a weekend of damp mornings, it still looked and smelled like new after a quick wash.

Relax in comfort with a warm, cozy chair blanket for those weekend getaways.
