Lightweight dry storage for water sports

The Lowepro SP921DB is a 5L waterproof dry bag built for adults who need compact gear protection during kayaking, boating, camping or beach trips. Its unisex design and 0.6 lb weight keep the load minimal on shoulders or across the body.

Roll-top closure with 0.02 in PVC wall

The single specification that decides fit is the 0.5 mm thick polyvinyl chloride construction combined with a roll-top seal. This creates the waterproof barrier rated for surface water sports but not for submersion, so buyers needing underwater protection should look elsewhere.

Stable carry under sustained splash exposure

Under continuous wave spray or rain the welded seams and 0.02 in material resist abrasion from sand and rock contact. The adjustable shoulder strap stays secure during prolonged paddling or hiking, and the integrated whistle remains accessible without opening the main compartment.

Questions about this item

How much gear does the 5L capacity actually hold when the roll top is closed?

The 5 litre volume fits a change of clothes, a towel and small electronics; rolling the top down three times seals the opening and reduces usable space slightly.

What closure system does the SP921DB use and how watertight is it?

A roll top with professional seamless construction creates a waterproof barrier for boating, kayaking and rafting, though it is not rated for underwater use.

What are the packed dimensions and weight of the Medium 5L dry bag?

It measures 4.191 x 9.398 x 32.004 centimetres and weighs 0.6 pounds, making it lightweight enough for cross body carry with the adjustable strap.
