SIRO Men's Sweater Pattern Kit in ANANAS by LANGYARNS
SIRO is a men’s knitted sweater worked in ANANAS by LANGYARNS, a DK weight yarn composed of 70% Lyocell, 30% Pineapple Fibres . The pineapple fibre is made from the leaves of the pineapple plant — material that would otherwise be treated as waste — and is processed using sustainable methods without bleach, with an enzyme wash used to remove impurities and a mechanised process designed to minimise environmental impact. In the finished yarn, the pineapple element brings a gently rustic look and feel without being scratchy, whilst the Lyocell adds a subtle sheen and a smooth, breathable quality that suits textured stitchwork beautifully.
The sweater is finished with ribbing at the base for clean structure and a neat outline. A fantasy pattern is worked throughout the body and sleeves, using a cable needle to create raised texture and definition across the fabric, resulting in a surface that feels detailed, rhythmic, and quietly expressive.
This kit includes the LANGYARNS ANANAS required for your selected size and the original LANGYARNS FATTO A MANO 284 pattern publication featuring SIRO.
