Hi there!
Are you referring to a normal collection section with two columns on mobile? We've actually just launched a Shopify app that let's visitors swipe through your products: https://apps.shopify.com/hypeswipe
It's very customizable, you get swiping insights, and you don't have to make any changes to your theme. I've been running my own shop for the last 5 years, and we've already seen a boost in session times & conversions after installing the app.
Would love your feedback when you get the chance, and I'll gladly answer any questions you might have!
