Waterproof Camping Bag Capacity Guide for Wholesale Buyers
Sealock is a waterproof camping bag manufacturer and wholesale supplier. For a distributor or retail buyer, capacity isn't a technical question — it's an assortment question. Which litres you stock decides your sell-through, how much cash sits in slow-moving sizes, and whether a customer finds the bag they came for. Carry too narrow a range and you lose sales; carry every size and you tie up capital in the tail. This guide covers which capacities actually move, how to build the size mix, and the labelling and logistics details that catch wholesale buyers out.

Sealock Completes an OEM Production Run of Welded Waterproof Gear Bags for an Overseas Brand
A batch of matte-grey welded waterproof gear bags has moved off the assembly line and into final inspection and packing at Sealock (Dongguan Yifulong Outdoor Products Co., Ltd.). Built to an overseas brand customer's specification, the order pairs a wide-mouth waterproof tote with a roll-top waterproof carrier, and is now being poly-bagged and crated for shipment. It is a routine but telling snapshot of what a dedicated waterproof-bag manufacturer looks like at full pace.

IPX7 Waterproof Waist Packs — Welded, MOQ 300 | OEM Factory
Sealock is a waterproof waist pack manufacturer in China supplying OEM, ODM, and wholesale buyers worldwide. The waist pack looks like the simplest bag in a catalogue, and it is the one most often faked: the market is full of "waterproof" fanny packs whose seams are stitched and whose zippers are ordinary, which soak through in the first real downpour. Building one that genuinely keeps a phone and a passport dry — while staying comfortable on a running waist and small enough to disappear under a jacket — is a welding and pattern problem, and it's what separates a specialist factory from a general bag workshop.

Welded Camping Dry Bags 20–80L — MOQ 300 | China & Vietnam
Sealock is a waterproof camping bag manufacturer in China supplying OEM, ODM, and wholesale buyers worldwide. "Camping bag" isn't one product — a campsite needs a dry sack for a sleeping bag, a duffel to haul the kit, a roll-top pack for the trail in, and a small dry bag for a phone and documents, and each has to keep water out through rain, river crossings, and a bag set down on wet ground. Building all of them on one welded platform, to a rating that survives real conditions rather than a marketing label, is what a specialist waterproof factory does. This overview sets out the range, the construction, and the sourcing terms.

OEM Waterproof Waist Pack for Outdoor Brands
Sealock is an OEM waterproof waist pack manufacturer and supplier for outdoor brands. A waist pack looks like one product, but outdoor customers don't buy it that way — a paddler, a fly fisher, a trail runner, and a mountain biker each want something different from the same small bag, and a pack tuned for one will get returned by the others. For a brand building a waist pack line, the job is to decide which activities to serve and then spec each pack to the way that customer actually moves. This guide sets out those differences and how a welding factory builds to them.

OEM Waterproof Camping Bag for Outdoor Brands
Sealock is an OEM waterproof camping bag manufacturer and supplier for outdoor brands. A camping brand almost never needs a single bag — it needs a coordinated system: a dry sack for the sleeping bag, a duffel to haul the kit, a roll-top pack for the trail in, all sharing a look, a colour story, and a waterproof standard. The leading outdoor names build camping carry as a range across capacities, not a one-off, and the factory's job is to deliver that consistency at volume. This guide covers how an outdoor brand builds a waterproof camping line via OEM — the system, the spec decisions, and the details buyers judge.
