After all, no one wants to be laced up, warmed up, and ready to hit the pavements, to then have to deal with overly tight, chafing pants that leave our downstairs area feeling hot and bothered. Running underwear is available from a whole load of brands, from sports retailers to shapewear companies to names like Runderwear, whose entire business focuses on creating perfect running underwear. Of the running underwear I reviewed for this piece, the Boody G-String is the one that resembles ‘normal’ underwear the most. I love how comfortable this feels and it’s also super soft. The colours are nice and the fabric is really gentle on the skin, plus there are zero seams showing; so, when I was sporting my very tight shorts, everything was smooth and bump-free.

I love a G-string, primarily because they have that barely-there feel, and this pair is no different as it fits comfortably against the skin and is super soft. Because they need to be breathable, soft and ideally not show up under leggings, running underwear is usually made of different, more expensive material than normal underwear. The fabric is super soft and I didn't feel too warm in this, although there isn’t much fabric in the first place so that might be why! They’re also incredibly comfortable and they come in different styles too so if you fancy a shorts-type pair of undies, then it’s an option.The fact they’re seamless means they don’t show under tight leggings and they didn’t budge at all as I walked and ran, despite feeling so light.

THEY might not be visible, but the best running underwear can really play a part in how comfortable you feel on your jog.Runderwear is one of the OGs of running undies and I’ve worn its running briefs on several occasions.

The high leg is really flattering and even though these might not look it initially, they’re actually pretty damn sexy. These have been made with thermoregulating fabric too so everything stays cool and dry. So although it might sound obscure to wear a thong made out of bamboo, there's a very good reason as to why you might choose it. Bamboo is a big, BIG business these days when it comes to sustainability as it requires less water than cotton to grow and it doesn’t require fertilisers and other chemicals. If it’s a soft thong you’re after, then a pair of these Reebok thongs will do. I barely noticed I was wearing undies when I did my leg workout and a 6km run in these. Plus, despite my extremely sweaty state during the workout, this thong literally didn’t even look damp. That’s a winning pair of running undies in my eyes! To say I'm slightly run-obsessed is probably an understatement, so it’s safe to say I’ve worn my fair share of uncomfy exercise undies. But, in the name of fitness, I’ve rounded up the BEST of the best when it comes to running pants and thongs.A pair of these will do you well next time you hit the streets or the treadmill… The best running underwear, at a glance This thong is ideal for running as it doesn’t dig at all and fits seamlessly underneath leggings and shorts. It’s also generally comfortable and works well whatever you’re doing; from running errands to sitting around the house.

I felt zero chafing during my run whilst wearing a pair of these thongs, plus these are seamless, so there are no obvious underwear signs underneath your tight gym kit. Are you supposed to wear underwear with running shorts? The general consensus is that this comes down to whether or not you're wearing lined running shorts. Let’s not beat around the bush; when we run, we get sweaty, and down there is no different. So, underwear that keeps us cool and dry is vital. Available in a multitude of colours and prints, these bikini briefs (AKA, pants) are great for running, lounging, or just general wear.I love the waistband of these pants too, as it isn’t too tight or overbearing; instead, it sits snugly against my skin. If the shorts you're wearing contain a liner, they're fine to be worn without underwear, and some experts say that wearing underwear as well as lined shorts can lead to excessive sweating. If you want to wear underwear with lined running shorts, though, you're entitled to do so. Instead, we want soft fabrics, ideally seamless so there are no lumps and bumps showing through our leggings, that dry fast. However, if you're wearing unlined running shorts, wearing running underwear can help prevent sweating and offer support and comfort. Where to buy running underwear Boody says that this G-String has been designed following a seam-free process to ensure less waste, so the sustainability credentials are there too.
