Torm B1 Base Layer



Very comfortable Sportwool base layer at an excellent price – basic design but it works

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

Good scores are more common than bad, because fortunately good products are more common than bad.

This extremely comfy Sportwool base layer comes at an incredibly affordable price. The particular variety of Sportwool used here is a lightweight mix that’s 39% merino wool and 61% polyester. As with all Sportwool, you get the wool on the inner face next to your skin, and the tougher polyester on the outside for extra durability.

The wool used is super-fine so it feels really soft and smooth, and it does a good job of absorbing moisture and wicking it away when you sweat. This base layer isn’t nearly as light as some purely synthetic ones and it can get weightier when you sweat heavily, but it stays comfortable because it doesn’t feel cold when damp – well, not unless you stop for ages.

We prefer a man-made fibre next to the skin for rides when we know we’re going to sweat a lot, but for low intensity rides where warmth is all-important, Sportwool is a great option. It provides plenty of insulation which is why we tend to use it most in the off-season. That’s a personal preference, though – we know plenty of people who prefer the feel of wool whatever ride they’re doing, and it’s certainly better at resisting odours than most synthetic options. Even with the polyester content of this Sportwool, the B1 smells reasonably fresh when you nip into a garage for a mid-ride Snickers bar – although it isn't as odour-resistant as pure wool.

The cut of this base layer is slim and there’s enough give in the weave for it to feel comfy even if it’s a snug fit. The slightly extended rear keeps your lower back covered when you’re stretched out on the bike while the collar is a typical T-shirt style. We’d actually prefer it a little higher to keep draughts off the neck but, again, that’s an individual choice.

All the seams are flatlock stitched so you can’t even feel them let alone be annoyed by them, and although after a few washes the cuff and hem bands aren’t quite as white as they were, the B1 can go through the machine without any worries. The same goes for the tumble dryer – no problems there.

It’s available in white with black bands too.
