Icebreaker Oasis LS Crewe Review


The original merino base layer, Icebreaker’s Oasis Crew is made from 100% super-fine 200gsm responsibly-sourced wool. The stylish cut with offset shoulder seams works well on its own or as an underlayer. There are no zips, pockets or synthetics – just soft, breathable, naturally antimicrobial wool that feels great and regulates your temperature.

Verdict: 9/10

The original soft and comfy 100% merino base layer.

Tribesports Engineered LS Top review


Made from a soft, durable nylon/polyester mix, this form-fitting base layer is cosy, comfortable and great at keeping you cool. ‘Engineered’ venting holes down the spine and sides, plus mesh panels, allow good air flow. Antibacterial treatment, thumb loops and reflective details finish a stylish top that works on its own or under an outer layer.

Verdict: 9/10

Great look and feel with superb features for runners.

Ashmei SS Baselayer review

Women's-Ashmei.jpg £65

We’ve used this base layer for a couple of years and it still looks, feels and smells as good as new. Made from a comfy, quick-drying fabric that mixes 65% non-mulesed merino wool with 35% carbon-treated polyester, it’s lightweight, durable, great looking and odour-resistant. We’ve worn it for everything from racing to casual wear.

Verdict: 9/10

Great-looking, great-feeling, great-smelling base layer.


Smartwool Merino 250 Pattern ¼ Zip review

Women's-Smartwool.jpg £100

A slightly heavier merino top at 250gsm, it works brilliantly as a warm and cosy base layer on cold days, or as an over layer. Made from 100% responsibly-sourced merino wool, it feels soft against the skin and, although warm, is very breathable. All those features, plus the deep zip, make it great for a winter run from start to finish.

Verdict: 9/10

Warm, cosy, comfortable and looks great.


BAM LS Bamboo Jersey review

Women's-BAM-Long-Sleeve-Baselayer-in-Hyacinth-Marl-£35-from-BAM.jpg £35

This soft base layer is made from 68% bamboo and 28% organic cotton, with 4% elastane for stretch. It’s comfy with a smooth, itch-free finish. Best suited to cooler weather, the simple design, crew neck and flatlocked seams allow it to sit well under another layer with no bumps. There are thumb loops for added warmth.

Verdict: 9/10

Great value, ethically sound and cosy in cooler weather.

Ronhill Infinity Merino review

Women's-Ronhill.jpg £43.49

Made from a 50:50 merino and polyester blend, this long-sleeved zipped top is soft, light and breathable with good stretch. Double-thickness fabric around the collar and thumb loops adds extra comfort, while the deep locking zip gives good ventilation. Flatlocked seams with contrast stitching and a stitched logo give it a smart look.

Verdict: 8/10

Smart, light, breathable, well featured and great to run in.

Alpkit Kepler SS review

Men's-Alpkit-Kepler_SS_Mens_Blu.jpg £37

A great value, 100% ethically-sourced merino tee – the Kepler is comfortable with a looser fit than most on test, so doesn’t look out of place at the pub after your run. Seamless shoulders and flatlocked seams reduce chafing and a subtle Alpkit logo on the shoulder finishes it off nicely. Also available as a long-sleeved version for £49. 

Verdict: 8/10

Looser-cut merino tee, looks nice and excellent value.

Howies Merino LS Base Layer review

Men's-Howies-LS-Base-layer.jpg £55

Welsh ethical clothing company Howies use soft and breathable merino wool to make a stylish, comfortable and good value base layer. Seamless shoulders and a long cut make it comfortable with a pack, and the slim-cut style works well on its own or under other layers. It's itch-free, naturally antimicrobial, and temperature-regulating.

Verdict: 9/10

Soft, stylish merino base layer for year-round running.

Cool kit for a cool autumn

 Montane VIA Dragon (new for AW18) Price TBC 


This is a lightweight and breathable stretch mid-layer with Polygiene odour-resistant technology and, most interestingly, cuffs that transform into emergency windproof mitts. We have one in for an early test and can report it’s a beautifully smooth top that moves with you during a run, providing a nice competitive-type fit. We can’t confirm the windproof mitts, however, as the weather hasn’t produced anything more inclement than a minor shower for us to put the top through its paces. But we can report they are there and they do look like they’ll do a great job!

Compressport Multisport Shirt LS review

Men's-Compressport.jpg £50

This is a high quality, technical baselayer. The polyester/polyamide/elastane fabric is stretchy, seamless and close-fitting, offering good compression. The fabric is perforated like a high-tech string vest, designed to aid thermo-regulation. It keeps you cool even in very warm weather, with hydrophobic fabric wicking away sweat. 

Verdict: 9/10

High-tech compression top, great for year-round running.

Paramo Tempro Zip-Neck review

Men's-Paramo-(1).jpg £55

The deep zip offers good ventilation with a protective high collar. It's quite warm with a long, slim cut that works well on its own or under a jacket. The PFC-free polyester wicks well and dries quickly. It’s made in Columbia at the Miquelina Foundation, where Paramo provides vulnerable women with training and employment.

Verdict: 8/10

Warm and comfortable – ideal for the colder months. 

Dynafit Alpine Seamless SS Tee review

Men's-Dynafit-(1).jpg £55

This tight-fitting tee is made from a mixture of polyamide and polypropylene, using a seamless construction to prevent rub points. Although great in a layering system, it also works well on its own. The Dryarn fibres with a hollow fibre construction improve temperature regulation, and the anti-odour treatment keeps it fresh.

Verdict: 9/10

Top quality performance and looks, and good value too.

Sundried Olperer T-Shirt review

Men's-Sundried-Olperer.jpg £40

A light, slim-cut tee that looks and feels great on its own, or under layers in cold or wet weather. The polyester fabric – made from a mixture of recycled plastic bottles and coffee grounds – feels smooth against the skin, wicks sweat and dries quickly. The coffee grounds also add odour-resistance and increase the fabric’s UV protection. 

Verdict: 8/10

Ingenious use of recycled fabrics in a lightweight tee. 


Iffley Road Worthing Drirelease top review £85

The Worthing is an excellent lightweight long-sleeved top for cool spring or autumn runs. The half-zip provides good ventilation and the small pocket holds a key securely. The fabric is soft and comfortable and the classic styling really stands out. The cut is fairly slim, the fabric is soft and the quality is high – but so is the price!

Verdict: 8/10
A classic-looking top that's great for cooler runs.

Aussie Grit flint long sleeve review £67

A nice top that moves with you as you run – perhaps no surprise given it was the brainchild of Formula 1’s Mark Webber, a man who clearly has high demands from his apparel. It does wick and breathe well, but you'll want the weather to be on the cooler side. Definitely one for late autumn and then all winter long. 

Verdict: 8/10
Start hoping for cooler conditions – perfect.

Alpkit Koulin Trail review £25

The Koulin Trail carries the slogan ‘wear more, wash less’ thanks to the application of silver-based treatment Polygiene. The body-mapped mesh panels under the arms keep it breathable and odour-free, and the rear pocket is handy for keys and cash – although a zip would make it feel more secure. But at this price, it's hard to fault.

Verdict: 9/10
Does what it’s supposed to do at a fantastic price.

Tribesports Engineered Zip Tee £50

This shirt is ultra-light and fitted due to its stretchy polyamide material. It has a sporty look, reflective strips on front and back, a bright yellow zip and useful thumb-holes. The fabric is light and breathable, making it great for slower runs or as a pre-race top. After a few weeks of heavy use it still looks like new, giving it a very durable feel.

Verdict: 8/10
A great all-rounder that's lightweight and built to last.
