What is Lassie?

Lassie is a children's clothing brand owned by Reima Oy, a Finnish manufacturer of children's clothes. The Riverside Company's portfolio page for Reima lists Lassie as one of Reima Oy's other children's wear brands, alongside Tutta and Progress. The page does not describe the Lassie brand itself, so its founding year, founders and range are not stated here.

Ownership and group

Reima Oy was founded in 1944 in Kankaanpaa, Finland. Riverside, through its Riverside Europe unit, invested in July 2011, and the portfolio page lists an exit in April 2026 with no buyer named. Lassie is therefore part of a business that was in private equity ownership for around fifteen years, and its current owner after the exit was not verified.

Positioning

As a second brand next to Reima, Lassie can serve a different price level or customer group within the same manufacturing and distribution structure. The sources reviewed do not state its price positioning, so the mid market classification in this directory is an editorial estimate and not a sourced fact.

Distribution

No sourced information on Lassie's sales channels, store counts or markets was available. Readers wanting product details should consult the brand's current official channels.

Why it matters

Multi brand structures such as Reima Oy's let a children's clothing manufacturer address several price points while sharing design, sourcing and logistics. Lassie is part of this portfolio logic, which is why it is listed here with the Reima brand.
