Who should pick what

Only three hard shells made our list, because only three publish a price and enough specs to score. The OHS 36-inch is the roomiest and comes first; the OHS 30-inch is the lowest-priced 2.0 ATA steel chamber OHS sells; The Recovery Outlet's 34-inch is the cheapest at $27,900 but stops at 1.5 ATA and states no warranty.

None of the three states FDA clearance for the chamber. If 1.3 ATA is enough for you, a soft chamber costs a fraction and does.
