Owen R. ★★★★★ Oct 18, 2026

I was skeptical about needing a separate inflation sack, but this one actually seals better than the original, making the mattress inflate in way fewer breaths. It doubles perfectly as a storage bag too, which saves me from carrying extra gear.

Nicholas Q. ★★★★★ Oct 10, 2026

I picked this up as a spare for my Flex 3D and it inflates the mattress just as fast as the original. The fact that it doubles as a storage sack is handy for keeping everything together.

Eva ★★★★☆ Oct 13, 2026

Does the job as a spare inflation sack, and it doubles as storage for the mattress which is handy. Deflating the pad by hand takes a bit longer than I'd like, but it packs down smaller than the stuff sack I was using before.
