morinokawau Inflatable Life Jacket for Adults, Low-Profile Life Vest (Grey) — Manual PFD, 330 lb Support

This morinokawau inflatable life jacket (YSH700-Grey) is a low-profile, manual-activation personal flotation device designed to support adults up to 330 lbs and inflate within seconds for immediate buoyancy.

Compact and sleeveless, the YSH700 combines lightweight comfort with certified buoyancy and practical safety features. Constructed from tear- and puncture-resistant polyester Oxford, this manual PFD stays soft against the body while offering visibility, fast inflation, and simple maintenance. It’s made for people who want reliable support on boats, kayaks, paddleboards, or while fishing, and it’s built to be rearmed and reused after deployment.

How quickly will the vest inflate when I need it?

The YSH700 inflates in roughly 2–3 seconds after you pull the manual activation handle, delivering rapid lift to help keep the head above water. If you prefer or need to top up inflation, an oral tube is included as a backup. The CO2 inflation system uses replaceable 33g metal cartridges with 1/2 inch threading for straightforward field replacement.

• 2–3 second inflation via manual pull
• Backup oral inflation tube for topping up
• Replaceable 33g CO2 cartridges for rearming
• Factory-tested air retention: ≤5% buoyancy loss after 24 hours

What size range and weight does this life vest accommodate?

Designed for adult users from 80 to 330 lbs, the vest fits a wide range of chest sizes thanks to adjustable straps and a front closure. Chest sizing covers approximately 29 to 62 inches, so single models can serve multiple family members or rental fleets without a bulky fit. Adjustability ensures the PFD remains snug and secure during active water use.
