Short answer: the Tribit Stormbox Flow for battery life, the Bose Soundlink Flex for durability. The Flow runs up to 30 hours, roughly double most rivals and about 20 to 24 hours with XBass on, but its midrange and bass are weirdly recessed about 4db below 700Hz. The Flex is IP67 rated, though its warm sound with overly boosted bass drowns out midrange detail.
On the Bose Soundlink Flex side: IP67 rated. The tradeoff: Warm sounding with overly boosted bass which drowns out midrange detail.
The case for the Tribit Stormbox Flow: Up to 30 hours of battery life - roughly double most rivals (~20-24 hrs with XBass on). Set against that: Midrange and bass are weirdly recessed about 4db below 700Hz.
Buy the Bose Soundlink Flex when sound quality outweighs the price for you, and the Tribit Stormbox Flow when the price outweighs sound quality instead.
There is a real battery-life gap here: the Tribit Stormbox Flow is rated for 30 hours, the Bose Soundlink Flex only 12 hours.

Tribit Stormbox Flow: $79.99 Tribit eBay
Pros: Up to 30 hours of battery life - roughly double most rivals (~20-24 hrs with XBass on). IP67 rated with a loose handle for carrying/hanging. Pairs with a second Flow for stereo; USB-C port charges your phone too. Measured bass extension of 47Hz (-10dB).
Cons: Not stereo. Midrange and bass are weirdly recessed about 4db below 700Hz. You need xbass mode for it to not sound like a clock radio with missing bass. You also can’t turn up the bass enough in the custom EQ modes to get it neutral, so it will sound bass light. Firmware 1.2.3 fixes the distortion issues with xbass mode on, but bass still sounds wobbly and uncontrolled.
