9PR: Winter activewear — 9Product Reviews

As someone who works out in the mornings, the sound of my alarm currently fills me with dread. Not because I don't want to go to the gym, but because it's freezing.

However, if I have my space heater within reach and some toasty winter workout clothes prepped in a neat pile, I'm much more inclined to make it out of bed in the morning.

So, if you're finding it hard to motivate yourself to move in this cold weather, we have a few suggestions that'll make your workouts (plus travelling to and from the gym) a little bit warmer.

Tops

Lorna Jane Amy Thermal Active Zip Through Jacket

Buy it for $160

This slim-fit jacket from Lorna Jane is an excellent option for a workout jacket. It features Thermal-Luxe fabric, which has a brushed fleece lining to keep you toasty during your workout. It also has four-way stretch and a compressive design, ensuring it stays in place as you move around.

Rockwear Thermal Long Sleeve Crew

Was $69.99, now $48.99

This long-sleeve crew from Rockwear isn't tight-fitting like most active jackets, so you can expect a bit more movement from the thermal fabric. While warming, it's still moisture-wicking, so you can trust you won't be bothered by sweat as you heat up during your workout. Featuring a wintry chocolate tone, it's also a great top for running errands or lounging at home.

CRZ Yoga Women's Fleece Cropped Sweatshirt

$46.75 on Amazon

Perfect for those who love to run on cold mornings (or hate it, but do it anyway), this cropped sweatshirt has a lightweight fleece lining. Designed to keep you warm without weighing you down, it also works as a layering piece if you tend to get quite hot during your workouts. Featuring a ribbed collar and cuffs, and a double raw hem, it's also a chic piece for casual weekend days, too.

Lululemon Define Jacket Nulu

Get yours for $149

The Define Jacket from Lululemon is crafted from trademarked Nulu fabric. Designed to be soft, stretchy and sweat-wicking, it won't provide a heap of warmth, but will insulate you as you move through your workout. You may need an extra layer as you head to the gym or your Pilates class, but it's ideal if you want to stick to long sleeves while exercising.

Leggings

Lululemon Fast and Free High-Rise Thermal Tights

$149 on Lululemon

With a soft, brushed interior, your legs will be super warm as you work out in these thermal leggings from Lululemon. Retaining stretch and shape with added Lycra fibre, they'll last you for winters to come. They feature two drop-in pockets on the legs that'll easily fit your phone, as well as three smaller waistband pockets for smaller items like keys.

CRZ Yoga Thermal Fleece Lined Leggings

$55 here

The CRZ Yoga leggings are not only affordable, but renowned for their high quality. They offer decent stretch and thickness, and this pair have a thermal lining for freezing winter days. We also love their super high-rise design and the phone pocket.

Lorna Jane Amy Thermal Phone Pocket Full Length Leggings

Get them for $140

The Amy leggings from Lorna Jane are a go-to for so many women, and their thermal-lined pair are a winter essential. Made from Thermal-Luxe material, they'll keep you warm with their brushed fleece lining while also offering four-way stretch.

TSLA Women's Thermal Tummy Control Yoga Pants

Just $32.98 here

Another Amazon-based brand, the TSLA thermal leggings boast a 4.6/5 stars across 116 reviews. This is quite impressive, given they only cost $32.98! They offer an ultra-soft thermal lining to insulate your legs, as well as four-way stretch, a high-waist design, a phone pocket, and a range of colours. Grab a pair now and don't let the cold distract you as you move through your yoga poses.

Hoodies and jackets

While these are probably too warm and cosy for a workout, we wanted to offer some options to get you to and from the gym or yoga studio. Mornings and evenings are the toughest in winter, so make sure you treat yourself to a jacket or hoodie that feels like a warm hug as you tick off your daily exercise.
