Lusso Pain Cave Eco Summer Base Layer



Very good summer-weight baselayer made in the UK from recycled materials
Fast wicking
Not as versatile as some – gets a bit cool if the temperature suddenly dips

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.

The Lusso Pain Cave Eco Summer Baselayer is its fastest wicking, most lightweight and ethically sourced baselayer. Crucially, performance lives up to the hype, and though primarily designed with balmy summers in mind, it's a good bet for indoor training too.

The baselayer is made from a 93% recycled polyester/7% elastane mix, the polyester component acquired from recycled PET bottles. This kind of reclamation, though welcome, isn't a new concept, but traditionally the fibres have felt slightly synthetic against the skin. Lusso has apparently been working with its suppliers to address this, and the result is pleasingly soft and smooth.

Continuing this theme, Lusso says the garment meets OEKO-TEX Standard 100 certification. This isn't an environmental accreditation in the classically accepted sense, but refers to the lack of harmful substances, thus safe for the wearer.

There are five different designs to choose from, all employing sublimation printing. Skulls and pain not really your bag? 'Bike Addict', 'I'm not a Climber', and 'Rest Day' are alternatives. Black goes nicely with everything and on the rare occasions I've dropped a jersey zipper, I thought the skull and crossbones logo looked quite funky.


Lusso's sizing chart is accurate and the medium fitted my 1m 81cm, 70kg frame perfectly. I'm broader across the shoulders than my build would imply, but as it's a sleeveless design it wasn't an issue. It sits second-skin close, with ample give and length, so no issues when alternating between tops, hoods and hunkered low on the stem.


Bottom line, it's delivered exactly what I expect from a decent quality baselayer. The synthetic weave is soft and smooth against the skin, not comparable with pure merino but not particularly synthetic either.

The lightweight material undoubtedly helps, but wicking prowess is swift and, to date, any misting (experienced indoors, on the turbo trainer, given the chill weather) around the chest and lower back was very fleeting. I could essentially sit back and hammer out a 90-95rpm and remain comfortable throughout – even with the heating wound up to 25 degrees.

Out on the road, the song remains the same, although it's worth noting I donned a long sleeve, middleweight winter jersey, or one of my favourite jersey cum jackets. In these contexts, and when the temperature began to plummet, I became more aware of chill than when wearing a lightweight merino base. Yes, I know it's a summer garment but something to bear in mind on longer, late summer rides when it can turn a bit nippy.

Odour management in synthetics has improved quite considerably in recent years and this one's no exception. I've worn it for five successive rides over different distances/contexts, and even with two 45-minute turbo sessions in the mix, it remained socially acceptable.


Machine washed at 30/40 degrees, with minimal detergent, and to date it still looks packet fresh, with no issues of bobbling, fraying or snagging. Being a printed design, the graphics have also held up. I've also treated it to a couple of hand washes, using soap flakes and warm water – campsite stylee – and again, it came up fresh and fragrant.

In terms of drying times, bargain on 20 minutes outdoors with a moderate breeze, 30 on the clothes horse at room temperature.


A penny less than £30 isn't a lot of money when it comes to baselayers, but there's still quite a lot of capable competition if you scout around.

Van Rysel's Cycling Summer Training Base Layer, a mesh design with similar performance objectives as the Lusso, comes in at a mere £14.99. However, as far as I can tell, it's not made from recycled materials and the design is perhaps a little 'plain Jane' by comparison.

An extra fiver buys its Sleeveless Base Layer Ultralight Race. Another mesh design, it's only available in a 'one size fits all', which may be a serious deal breaker.

Dhb's Lightweight Mesh Sleeveless Base Layer is closer in price to the Lusso at £25; it's made from 93% polyester, 7% elastane, and features flatlock seams and an 'anti-odour' treatment.


Overall, the Pain Cave is a sensibly priced and surprisingly comfortable synthetic summer baselayer, with the fact that it's made from recycled materials and without impairing comfort, or performance, another plus.

Size tested: Medium

Tell us what the product is for


These base layers started life out as plastic bottles. PET bottles can be recycled into a wide variety of products including polyester fibres. We have been working with one of our fabric suppliers to produce this new mesh material that is as soft and lightweight as non recycled versions, so there is no loss in quality.

This multifilament yarn contains 93% recycled polyester for its lightweight and high moisture transfer properties, 7% elastane for flexibility and a better fit, resulting in a super light base made for the heights of summer.

The full body design has been achieved via sublimation printing that allows us to add colour from seam to seam.


The fabric has been OEKO-TEX Standard 100 certified."

My feelings – it's a tactile and high performing summer weight base layer with funky styling and eco-friendly credentials.

Rate the product for quality of construction:

Thin yet surprisingly sturdy fabric. Neatly executed throughout. No loose stitching or signs of deterioration to date.

Rate the product for performance:

Very comfortable next to the skin and wicks fast, which is not surprising given the thin fabric, but will retain some welcome heat, should the temperature dip slightly mid-ride.

Rate the product for durability:

Fabric feels very thin but is incredibly stretchy and resilient. No loss of shape, or anything similarly untoward in several weeks of constant wear and washing.

Rate the product for fit:

Medium was bang on for me. However, while I stand and weigh a very average 181cm, 70kg, I'm proportionally short in the torso.

Rate the product for sizing:

Bang on for me, but worth noting my previous comments.

Rate the product for weight:

Feels remarkably light and unnoticed in the most positive sense.

Rate the product for comfort:

Very good, in every respect.

Rate the product for value:

Its £29.99 rrp isn't particularly pricey, especially when factors such as performance and recycled materials are factored into the equation. Nonetheless, Van Rysel's Cycling Summer Training Base Layer comes in at a mere £14.99, and an extra fiver buys its Sleeveless Base Layer Ultralight Race. Dhb's Lightweight Mesh Sleeveless Base Layer is closer in price to the Lusso at £25.

How easy is the product to care for? How did it respond to being washed?

Thus far, very straightforward. Pop in the machine at 30/40°C and swerve the drier. Has responded very well and looks new several weeks down the line.

Tell us how the product performed overall when used for its designed purpose

Overall, the Lusso Pain Cave does an excellent job of regulating temperature and odour. The fibres respond quickly to rider effort, and coupled with the thin tog weight has meant clamminess, odour and sweat marks have been conspicuous by their absence. Jersey quality obviously plays a part, but it's been consistently good with several ranging from Lusso's own to middleweight long-sleeve designs on cooler days.

Tell us what you particularly liked about the product

Softness, light weight, practicality.

Tell us what you particularly disliked about the product

Nothing, given the design brief.

How does the price compare to that of similar products in the market, including ones recently tested on

Cheaper than some, more expensive than others but then, it has some unique features. Dhb's Lightweight Mesh Sleeveless Base Layer is probably its closest rival at £25.
