At a Glance

Product Description

SL-I015 is a 10 L soft cooler measuring 30.5 × 20 × 25 cm (12 × 7.9 × 9.8 in) outside and about 27.5 × 17 × 22 cm inside, holding around 12 standard 330 ml cans without ice. It weighs about 0.9 kg. The shell is orange TPU-laminated nylon over 15 mm of closed-cell foam on every side including the lid, and the blue food-grade TPU liner is welded into a single tub with rounded corners. The body is high-frequency welded with no stitched seams. The lid opens on an airtight waterproof zipper running around three sides, fitted with a large moulded ring pull. Each end carries a moulded D-anchor on a welded patch, and the detachable shoulder strap clips to these anchors with carabiner-style snap hooks. The strap has contrast stitching, a ladder-lock length adjuster and an orange padded shoulder section. A black wear band wraps the base.

Sized for One or Two

At 10 L, SL-I015 holds a day's food and drinks for one or two people without the bulk of a family cooler: around 12 cans, or lunch containers with a couple of bottles and an ice pack. It hangs at the hip on the shoulder strap, leaving both hands free, and fits on a car seat, under a desk, in a kayak hatch or beside a beach chair. Because it is carried on the strap rather than by a top handle, the lid is clear of webbing and opens fully.

Construction and Water Behaviour

The shell, liner and anchor patches are high-frequency welded, so there are no stitch holes in the cold compartment or through the outer wall. The D-anchors are mounted on welded patches, never stitched through the body. Melt-water stays inside the food-grade TPU liner instead of reaching the foam, so the insulation stays dry and the cooler does not hold odour.

Cold Holding

Packed with ice, closed and kept out of direct sun, the cooler holds ice for up to 48 hours in our trials at 25 °C ambient. The airtight zipper removes the air leak along the closure that lets warm air into coolers with a standard zip. A small cooler has less thermal mass than a large one, so pre-chilling the contents and keeping it in the shade make a bigger difference here. Results change with ambient temperature, sun exposure, how often it is opened and whether the contents were chilled before loading.

Quality Inspection Standards

Every production run is checked at IQC, IPQC and OQC. The suite covers load testing to 1,500 cycles on the shoulder strap and anchors, zipper fatigue to 3,000 cycles, tensile and bonding strength on welded seams and anchor patches, salt-spray on snap hooks, abrasion on the base band, colour fastness and colour difference against the approved sample, and full water-immersion testing on finished coolers. Third-party inspection by SGS or QIMA can be arranged at the buyer's cost.

Product Highlights

Compact 10 L capacity for one or two people, about 12 cans. Seamless high-frequency welded body with a food-grade TPU liner. Airtight zipper with ring pull, IPX7 and leakproof in any orientation. Detachable padded shoulder strap on welded D-anchors. Black base wear band. MOQ 300 with custom colours and logo.

Printing and Logo

The front panel is clear of webbing and pockets, giving a full flat area for a logo. Screen printing suits solid one- to three-colour marks and resists UV and salt. Heat transfer and UV digital printing handle multi-colour and photographic artwork. Welded TPU patches and raised silicone prints give a tonal, textured mark, and the shoulder pad can carry a second logo. Artwork is required as vector files; a digital placement proof is returned before sampling.

OEM / ODM Capability

Sealock has manufactured insulated and waterproof gear for over 20 years, with factories in Guangdong, China and Ho Chi Minh City, Vietnam — the second site giving brands a non-China origin option where tariff exposure matters. We hold ISO 9001, BSCI, SMETA, Higg, GRS and SCAN certification, and produce insulated products for brands including STANLEY, Hydro Flask and CORDOVA.

The cooler body is high-frequency welded, while the shoulder strap and pad are sewn, and sewn construction is an equally mature in-house capability rather than an outsourced step. Most demanding requirements can be met, from a colour and logo change to a top handle, extra pockets, larger sizes or full custom development; complex development with new tooling adds time to the first sample cycle, which is worth planning for early.
