ThermoBall Jackets

Standard or inflatable personal flotation device (PFD)? 

• Standard: Low-maintenance, always buoyant, great for various water sports, often with pockets. Can feel bulky, restrictive and hot while paddling. 
• Inflatable: Slimmer profile and comfortable, but must be inflated to work so not great for high-impact activities, kids under 16, nonswimmers or situations where you might end up injured or unconscious before you can inflate. Requires regular maintenance and replacement of carbon dioxide cartridge. 
• Hybrid: Balances features of both, with a heftier price tag. 

What conditions will you encounter? 

• Level 50: For competent swimmers and activities like kayaking and paddle boarding, where mobility is needed but quick rescue is expected.  
• Level 70: For calm, inland waters where fast rescue is likely. 
• Level 100: For rough or remote waters or offshore where rescue may take a while.  

Finding the right fit 

• Try on PFDs with your paddling clothes to get the best fit.  
• Mimic paddling motions to ensure there’s no chafing. 
• Make sure it works with your seat without riding up or feeling uncomfortable. Shorter PFD work well for kayakers.  
• If possible, test your PFD in a pool or shallow water; it should not ride up or slip over your chin while floating. 

Which insulation do you prefer?

• Down: Ultralight, warm and packable—but won't insulate when damp and dries slowly.
• Synthetic: Insulates when damp, dries fast and often less pricey than down—though heavier and less packable.
• Wet or humid conditions or high activity? Consider water-resistant down, synthetics or down/synthetic hybrids.

How much will temperature and weather vary?

• Most insulated jackets feature water-resistant shells. Some use waterproof/breathable material.

• For high-exertion activities, look for vents in the underarm or core area to dump heat.
• Some jackets vary insulation and shell materials based by body zone to provide weather protection and breathability where needed.

Consider features:

• Hoods: Add warmth and protection; some are detachable or helmet-compatible.
• 3-in-1 jackets: Combine an outer shell and midlayer that zip together, so you can wear separately or as one.
• Pockets: Designed to stash gear, secure valuables and more.
