Womens Merino Base Layers | Smalls Merino at the bonnie mob

Smalls Merino Women's

Merino for grown-ups, in UK sizes S to XL. Camisoles worn year round, polo necks and long sleeve tops, the 24 Hour Trouser in two weights, and a pure merino sleep mask. 17.5 micron ultrafine merino — the underlayer Tracey packs for every ski trip.

Merino for grown-ups

The camisole is the year-round one. Tracey wears hers all year. Fine merino is a summer fabric as much as a winter one — it breathes and moves moisture away, so it works in August as well as it does in January.

Ski underlayers, without the bulk. The long sleeve top and the 24 Hour Trouser go under a salopette and are forgotten about. The trouser comes in 190g lightweight for spring snow and everyday wear, and 280g heavyweight for a proper cold week.

Polo necks worth owning. In midnight, grey marle, emerald green and chocolate brown — good enough to wear on their own, thin enough to layer under everything else.

And a merino sleep mask. Padded with traceable wool rather than the recycled polyester most brands use, so it regulates temperature instead of making your eyes hot. One of the kindest presents you can give someone who is not getting much sleep.

UK sizes S to XL. 17.5 micron ultrafine merino — ZQ-certified New Zealand wool, spun in Biella and made up at a family-run factory in Portugal. Buy once, buy well — and then find you are not willing to pass it on.

FAQ's

What sizes do you stock?

UK S, M, L and XL. The sleep masks are one size.

Can merino be worn in summer?

Yes. Fine merino breathes and moves moisture away from the skin, so it regulates rather than insulates. The camisole is a year-round piece, not a winter one.

Which weight should I choose for skiing?

190g lightweight for spring snow, milder resorts and everyday wear. 280g heavyweight for a genuinely cold week, or if you feel the cold on the lift.

Is it itchy?

No. At 17.5 micron this is ultrafine merino, a far finer fibre than the wool most people associate with itching, which is why it can sit directly against the skin.

How do I wash it?

Machine washable at 30 on a wool cycle, dried flat away from direct heat. Never tumble dry. It needs washing far less often than cotton because merino resists odour.

Does it make a good gift for a new mum?

The camisoles and the pure merino sleep masks are the two to look at, and both appear on the gifts for new mums page. A sleep mask for someone who is not getting much sleep is a thoughtful present.

Where is it made?

The wool is ZQ-certified New Zealand merino, spun at an EMAS-certified mill in Biella, Italy, and made up at a family-run factory in Portugal.

Just discovered this shop and love the attention to detail and care that goes into the clothes. I ordered some baby cashmere in the sale and am really impressed with quality and value.

Adorable soft jumper. Very pleased with the quality and the design is so sweet. I would size up if in doubt, my son is 5 months and the 6-9 month fits well.

Mushroom Fleece Baby & Kids Organic Dress

I’m really impressed with the baby clothes I bought from Bonnie Mob! The organic cotton feels incredibly soft and gentle on my baby’s skin — you can truly feel the quality the moment you touch it. The fabric is well-made and durable, even after a few washes, and the designs are absolutely adorable. You can tell the difference compared to many other brands — Bonnie Mob clothes just feel more premium, comfortable, and thoughtfully made. Definitely one of my new favourites for babywear! 👶💛
