Frequently Asked Questions

How long can this pack keep my food warm/cold, and do I need to use ice packs?

The Day Pack features a high-density, multi-layered closed-cell foam isolation core engineered to maintain strict internal microclimates for up to 8 continuous hours. To maximize performance and keep your calculated macro meals perfectly cold, crisp, and fresh throughout your full workday or commute, we recommend adding a standard slim ice pack alongside your prep containers.

Is the interior liner completely leak-proof, and will the bag "sweat" on the outside?

Yes, it is 100% leak-proof. The interior liner is constructed using advanced radio-frequency (RF) electromagnetic welding to seamlessly fuse the seams without standard needle puncture holes, entirely containing accidental container spills. Additionally, the multi-layered insulation core acts as a total thermal block, completely preventing external condensation bleed or "sweating" from dampening your other office or gym gear.

How many meal prep containers can it hold, and how does the roll-top design work?

The Day Pack comfortably accommodates multiple standard-sized, airtight macro prep containers alongside your hydration flasks. Designed with a flexible geometric roll-top architecture and a heavy-duty tactical snap buckle, it allows you to easily expand the storage volume for days when you carry extra nutrition, or roll it down tightly to compress the pack and maintain a sharp, structured, minimal aesthetic.

How do I clean the interior liner if food spills, and will it retain stubborn odors?

Cleaning is completely effortless. Because the internal RF-welded seams are fused perfectly flat, there are zero stitched fabric flaps or needle grooves where food particles, moisture, or bacteria can hide. The liner is molded from a premium, stain-resistant, non-porous TPU layer that actively resists sour food smells—simply wipe it down with a damp cloth and mild soap for a pristine, hygienic finish.
