Saxx Roast Master Mid-Weight Tights: first impressions

Made with a material mix that's mostly comprised of recycled polyester, the Saxx Roast Master Mid-Weight Tights accompany the Saxx Roast Master Mid-Weight Long Sleeve top to provide base layer protection for your entire body. 

Thermal leggings are typically a fairly straightforward piece of kit, designed to do one job – keep your legs warm – but, being made by men's underwear specialists Saxx, these tights have a bit more about them. The upper section boasts the brand's trademark 'Ballpark pouch', which is purpose-built and designed to keep the relevant parts of the male anatomy securely supported and in a comfortable position while the wearer gets on with whatever outdoor pursuit they're engaged in. 

Fairly unusually, the design also offers a fly opening, for those moments when nature calls while you're out on the trails. The benefit of this feature is that you don't have to pull the entire top of the tights down in order to relieve yourself – something that's particularly useful when it's properly freezing outside.

Perhaps even more impressively, though, the vast majority of the material used in these tights is either recycled plastic, or Tencel Lyocell, an environmentally friendly fabric where the fiber content is derived from sustainable wood sources.

Saxx Roast Master Mid-Weight Tights: in the field

I have been testing my rather fetching 'Get Out Camo' patterned Roast Master thermal tights during a range of outdoor adventures and campouts amid the frostbitten forests, non-roasty coast and chilly hills of Devon during late autumn, midwinter and early spring. 

Aside from a few freezing weeks it has been more of a wet winter than a cold one in the south of England, but I have been very glad of the extra leg protection offered by these tights during some day hikes across the moors and early morning trail runs when the temperature hasn't managed to climb north of 0°C / 32°F. 

While not quite as luxuriously comfortable as full merino leggings, the synthetic material used in these tights means they remain lightweight and still provide excellent thermal protection even when they get wet. Polyester fabrics are hydrophobic, meaning the fibres absorb very little water (less than 1% of the garment's weight), so you never feel soaked through like you do in wool or bamboo-based leggings, even if you get caught out on the trails in torrential rain. They also dry extremely quickly (far faster than merino or bamboo), and keep your legs warm the entire time, when dry or damp. 

The synthetic material is pretty tough, and while these aren't quite as robust as dedicated running leggings, they perform well as an underlayer out on the trails.

The elastane content, although quite small, gives these tights plenty of stretch, so I never felt like my freedom of movement was in anyway inhibited when I was walking, running, hiking and biking, whether I was wearing the leggings beneath trail-running shorts, hiking trousers or rain pants. I haven't yet worn the Roast Masters beneath salopettes or ski pants in the snow yet, but they'll certainly provide a good defense against the cold.

The downside of the synthetics is that they're not as breathable as natural materials, and can get a little sweaty during high-energy activities such as skiing and running. The Tencel Lyocell content does seem to introduce a level of softness and comfort that's lacking in some synthetic leggings I have tested in the past, however, and there is certainly no plastic feel or static crackle when you pull them on.

And so to the Ballpark feature, which is one of the big selling points of these tights. Don't worry, I won't go into too much detail, but suffice to say this pouch does its job well, keeping everything in place and reducing the risk of discomfort, chaffing and other undercarriage unpleasantness. It's good to see some considered design going on here, because bog-standard leggings can be pretty horrible to wear during outdoor activities, and you shouldn't have to sacrifice comfort for warmth in these halcyon days of high-performing outdoor apparel.

The fly opening is useful too – especially when it's cold enough to freeze the balls off a brass monkey outside. Between the Ballpark pouch and the fly features, there's little doubt what side Saxx leans towards when it comes to the old dilemma of whether undies should be worn beneath tights during outdoor activities – this is a resounding vote for going commando.
