Can you put ice in a soft cooler bag?

Yes, you can put ice in a soft cooler bag — loose ice and ice packs both work, but ice packs are the better choice for maximizing cold retention and protecting the interior lining over time.

Soft cooler bags like the Hulongo 30L and 52-can models use a seamless hot-press PEVA lining specifically designed to handle meltwater without leaking. Loose ice works fine for short trips, but it typically reduces the effective cold window by 20–40% compared to ice packs, depending on how often you open the bag. Ice packs distribute cold more evenly, don't pool at the bottom, and put less stress on the PEVA floor — which matters on bags you're packing and repacking regularly.

• Hulongo soft cooler bags use a seamless hot-press PEVA lining rated to contain meltwater without leaking.
• Ice packs extend cold retention by roughly 20–40% compared to loose ice under the same conditions.
• Hulongo's 30L cooler backpack holds temperature up to 12 hours with ice packs and pre-chilled contents.
• Hulongo's 52-can model extends cold retention to up to 20 hours with ice packs under optimal conditions.
• Insulation thickness across the Hulongo soft cooler line is 8mm foam — thicker than many competing bags in the same category.
