Nieprzemakalni

Nieprzemakalni is a Polish bag and backpack maker operated by Waldemar Kieresiński in Łódź. The company says it has produced to order there since 1989, using coated and waterproof fabrics.

Production in Łódź

It serves consumers, companies, institutions and advertising agencies. The site says it uses Polish and foreign materials, and accepts custom designs from one piece.

Bags and backpacks

The catalogue includes sports and travel bags, training bags, waist packs, wheeled bags and backpacks for tourism, daily use and promotion. It also lists cooler bags, shoulder bags and conference bags. Product pages show different formats, capacities and compartments.

Water resistant construction

Nieprzemakalni says it uses coated and waterproof fabrics for its bags and backpacks. One sports bag listing specifies polyester Rip-Stop fabric, a reinforced base and several external and internal pockets. Materials and construction vary by model, so product details should be checked before ordering.

Custom orders for organizations

Businesses and institutions can request bags or backpacks with a logo or printed design. The manufacturer says it can prepare a custom pattern and lists a two year manufacturer's guarantee for its products. This makes the range suitable for travel, sports, conferences, promotional use and equipment storage.

Public supply record

Polish public procurement records document commercial orders over time. In 2015, Waldemar Kieresiński Nieprzemakalni received an order for 10,000 eco bags. In 2026, Nieprzemakalni was named as the representative of a consortium awarded a framework agreement for sailing bags, alongside Armyworld.pl.
