Introducing the G.01 Vesikko, the world's first alpaca wool Submariner sweater. Crafted by Kasperi in collaboration with Alpa Knitwear. The G.01 Vesikko is designed to meet the highest standards of comfort, utility and durability.
The functional fit of the Vesikko, with its Raglan sleeve cut, makes for a sweater that keeps you warm, dry, and comfortable. An excellent choice whether you're about to sail the seven seas or just need a reliable sweater for work or outdoor adventures.
Perfect as a warm mid-layer, active outerwear or just by itself. Its timeless design makes it a good looking match for any occasion.
With the soft fibers of Alpaca wool, this sweater is much less itchy than other wool types. It's against the skin comfort is at another level. The special rib knit structure makes for a durable and breathable garment that keeps you warm outdoors and cool indoors.
Designed by Kasperi and made from ethically sourced Peruvian alpaca wool at Alpa's high-tech knitting factory in Lithuania.
The classic and timeless Submariner sweater has many navies around the world for close to a century now. For the G.01 Vesikko, we went back to the roots of maritime sweaters and upgraded it from the point of view of everyday comfort and utility. The Vesikko is named after one of the few Finnish submarines from the 1930s.
At Kasperi, we're passionate about products made for life. We demand high utility and durability from our designs, which is why we've collaborated with Alpa Knitwear for the G.01 Vesikko. We've been collaborating with Alpa using their alpaca wool crewnecks for over two years in all conditions. We fell in love with alpaca wool's qualities and envisioned the world's first Alpaca wool Submariner sweater. Alpa's decade-long experience in creating the highest quality pieces out of ethically sourced Peruvian alpaca wool aligns with our vision of making garments that stand the test of time.
We designed a piece and Alpa figured manufactured it. The result is not only the first alpaca wool Submariner sweater, but probably the best Submariner sweater out there.
Our nordic design philosophy is inspired by the timelessness of high quality pieces and the efficient use of resources. In the past, items were investments, and their utility and durability were essential. True future classics emerge when items stay in use for decades. That's why we're committed to designing Garments for those principles.
Functional fit, size true to your size. Janne in the first picture is wearing Large and is 188 cm and 88 kg. Michael in the fifth picture is wearing Medium and is 177 cm and 77 kg.

The antibacterial properties of Alpaca wool mean this garment will stay fresh with only airing out almost perpetually. If a wash is needed, hand-wash in a sink with cool or cold water.

Ihana villapaita
Super good sweater.
The temperature is regulated particularly well by the alpaca wool.
It is currently -3 Celsius in Belgium. I wear this sweater indoors and outdoors with just an undershirt and the G.02 korpi as a shirt.
I bought the Vesikko as a present for my son and it immediately became his favourite sweater. Highly recommended!
Extremely good. The best woollen sweater I've ever owned.
Perfect!! The sweater is beautiful, warm and wonderful to wear.
