Best phone case for riding (iPhone 6s plus)

I love this phone but it’s big! What is the best case to hold it while riding? It may be too heavy for an armband but what other choices do I have? And since I have a hardcase on it too it is even bigger.

Lifeproof? Otterbox? They both come with a belt clip.

I put my phone in a SPIBELT. Stretchy spandex pocket on a waist strap.

Spibelt all the way!

Thank you! I knew cothers would have great suggestions. All are appreciated!

I have the Otterbox and it’s great.

I have a lifeproof case. It makes my phone larger but better able to handle my abuse. Has been in the pouring rain, with me kayaking, and dropped numerous times in the dirt or on concrete (like all the time). My last phone got squashed while in a different case when my horse fell on it, but hopefully we don’t have to test that again… I think the otterbox might be better but it made my phone seem too massive.
