TPU stays flexible cold and takes the same crease repeatedly. The double zip-lock seals the top; the valve at the base opens under pressure and closes when you stop rolling. Down jackets and knitwear lose the most, roughly half their pack height. It works in reverse too, keeping wet swimwear off everything else on the way home.\u003c\/p\u003e\n\u003ch2\u003eWhat you get\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNo pump, no electricity\u003c\/strong\u003e — roll it down with your forearm or kneel on it, that is the whole method\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTPU, not brittle PE film\u003c\/strong\u003e — stays flexible in cold cargo holds and survives repeated folding\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDouble zip-lock seal\u003c\/strong\u003e — two parallel tracks, so a single bad closure does not vent it\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWorks as a wet bag\u003c\/strong\u003e — seal damp swimwear in on the way home instead of squeezing air out\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThree sizes\u003c\/strong\u003e — small for smalls, medium for a week, large for a down jacket or bedding\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReusable, not single-trip\u003c\/strong\u003e — rinse and air dry and it goes back in the case for the next one\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSizes\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSmall 40 x 30 cm, Medium 50 x 40 cm, Large 60 x 50 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eTPU film with double zip-lock track and one-way roll valve\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eApprox. 240 g (8.5 oz), large\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCompression\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eUp to around half the pack height on down and knitwear\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAlso suits\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eWet swimwear, damp towels, anything you want sealed from the rest\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCare\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eRinse, air dry fully open, store flat and unrolled\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch2\u003eQuestions about the compression bag\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eHow much air comes out without a pump?\u003c\/strong\u003e\u003cbr\u003eOn a down jacket, around half the pack height. On folded cotton, closer to a third. The limit is the air trapped inside fibres rather than between the clothes, and no pump removes that either.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill it survive a checked bag?\u003c\/strong\u003e\u003cbr\u003eTPU is the reason for the price difference. PE film bags crack along the fold after a few cold flights; TPU stays flexible.
