Best For: Backcountry Adventures – Airblaster Merino Ninja Suit

If we’ve said it once we’ve said it a thousand times, Airblaster’s Ninja Suit is the bomb. Whilst you might question it’s worth beforehand, once you’ve put one on you’ll never take it off. This ‘Wolverino’ (read: extra-stretchy merino wool) version ensures you don’t have to, as its natural antibacterial properties ensure it’ll remain stank-free, but the USP is clearly the all-in-one design that covers you from crown to ankles.

Not only does it eliminate having your top ride up under your jacket, it traps heat way more efficiently, meaning that on the right days you can ditch a layer and experience way more freedom of movement. We reckon even just having the hood up gains you an extra couple of degrees as the heat has even fewer places to go.

This all makes it perfect for riding powder and splitboarding up, where reliable and effective gear is key. Our video guy wears his well over 50 days a year working and playing in the mountains!

Best For: Bringing The Apres Game – Burton Midweight Merino Button Up

Sometimes, turning up at the apres bar and taking off your jacket to reveal some baggy old thermal doesn’t quite cut it. Enter Burton’s button up base layer, pure style points cut from 100% merino wool. If there’s riding underwear with more swag than this, we’ve yet to find it.

Not only does it look p.i.m.p., on test it performed as well as any other thermal and kept near bone dry even on super-humid snowy days pre-season. With a slightly looser fit it also scored high with our tester for splitboarding, as having an adjustable breathability from the buttons turned out to be a game changer for hikes in the sunshine.

Best For: Fer Da Gurls! – Mons Royale Boyfriend LS

It’s a sad but true fact that we haven’t currently got any female staff members here at Whitelines Towers, but never fear – we have an army of trusted testers that consistently provide us with quality gear reviews for the fairer sex. This time instructor Chloe Hardy hit us back with her thoughts on the Mons Royale Boyfriend Longsleeve – bearing in mind that if you’re working on the hill all hours of every day, you need to depend on your kit.

“I’m absolutely in love with this thermal; it’s super soft, really warm and dries mega fast. The shape is great, it’s nice and long and has a loose, comfortable fit. It’s perfect for spending a whole day shredding and looks great for après, too. Plus, you can wear it for plenty of other activities too, like hiking, running and yoga.”

Best For: Budget Price – DaKine Yoder Thermal

If your budget doesn’t stretch to merino, then we highly recommend this affordable alternative from mountain gear specialists DaKine. A combination of polyester and cotton makes it dry lightning-quick, and there’s an added odour-fighting treatment in the mix too.

We tested this in extremely cold conditions, and it never felt like it was coming up short. Plus its retro graphic looks great when you’re cooling off in the bar after the session, and you can thrash it in springtime slush without worrying about ruining something expensive.
