Cornish brand Finisterre makes great quality outdoor kit in nature-inspired colours, and its new bamboo range of base layers are stand-out pieces. The jersey material is pleasingly comfy – you can even sleep in these leggings on a winter camping trip. Unlike synthetic bottoms, these merino leggings have a soft, natural feel against the skin. These are firmly in the ‘underwear’ rather than the ‘leggings’ camp – it’s a pity they are too thin and see-through to work alone as workout bottoms, but as breathable long johns they’re a great quality choice. Finisterre Vela bamboo base layers (for women) and Bora bamboo base layers (for men): Best casual base layers In short, a good pair of leggings and a matching long-sleeved top can serve you well all year round – and they can help to eke the absolute best performance from all the other layers in your wardrobe, too. It’s well worth investing in a high-quality set – or several sets for longer trips – and in this article, we’ll explain what to look out for and recommend several of our favourite synthetic, bamboo and merino base layers for both men and women. Keep the bottom half of your body super snug in these brilliant merino tights. We love wearing these Icebreaker leggings as a base layer for walking and skiing – the 100% merino wool construction means that they’re delightfully warm, highly breathable and there’s enough figure-hugging stretch to stop them bunching up.

They’ll keep you snug in snow, but are breathable and comfortable enough to wear alone, and they’re durable too: we’ve washed them multiple times and they always come out looking and performing like new.

We love these soft neutral tops and bottoms for men and women because, unlike sportier-looking base layers, they work well for both casual day-to-day clothing and active adventures. The tops, in particular, look great with jeans when you aren’t out hiking, making Finisterre’s offerings good value for money – and that versatility is particularly welcome when you’re travelling light.
