Lighter, cooler, sleeker, plus all the added protection of Spherical Technology powered by Mips® and our new DryCore™ sweat management system: the Aries Spherical is like nothing before.

A helmet that feels like it isn't there: the all-new Aries™ Spherical is like nothing before. Its sleeker form and lighter weight (only 270 grams in size medium, CE certification), deliver sensational comfort and cooling power. Spherical Technology™, our ball-and-socket design powered by Mips®, adds protection by redirecting energy away from the brain in certain impacts, and Progressive Layering with dual densities of Nanobead EPS foam adds more comprehensive energy management. 24 Wind Tunnel vents are maximized by the AURA II Reinforcement Arch, while a plush DryCore™ brow pad manages sweat and combines with a network of intricately engineered deep internal channeling to elevate comfort. From the proven reliability and adjustability of the Roc Loc® 5+ Air fit system, to full lower hardbody coverage to enhance durability, to the meticulous production quality, the Aries is state-of-the-art performance, protection, and style.

FEATURES:

  • AURA II REINFORCING ARCH: The shatter-resistant and translucent Aura II Reinforcing Arch runs throughout the helmet; bolstering structural integrity and allowing massive vents for cooling
  • VIRGINIA TECH #1 RANKING: Researchers at independent testing facility Virginia Tech gave Aries Spherical their best score event in their rankings of which helmets best reduce the risk of injury. All Giro helmets with Spherical Technology have received their top level of 5 stars.
  • DRYCORE™: The DryCore™  sweat management system utilizes an internal silicone bead to redirect moisture away from the rider's brow and eliminate the irritation of sweat dripping into the eyes.
  • SPHERICAL TECHNOLOGY: Spherical Technology's Ball-and-Socket design; powered by Mips®; helps redirect impact forces away from the brain by allowing the outer liner to rotate around the inner liner during a crash. It also eliminates contact with hard plastic or slip-planes against the skin.
  • MIPS® BRAIN PROTECTION SYSTEM: All Giro helmets are designed to reduce as much energy as possible while meeting and exceeding stringent safety standards. The goal of Giro's Mips-equipped helmets is to reduce rotational forces. Giro believes that helmets equipped with this technology can reduce the amount of rotational force that may be transferred to rider's brain in certain impacts.
  • 21 WIND TUNNEL VENTS: Giro helmets are engineered with our proprietary Wind Tunnel venting system. This elaborate design combines active vents in the helmet's shell with exhaust channels inside the helmet that thrust cool; fresh air over and around the rider's head while forcing heat and stale air out.
  • DEEP INTERNAL CHANNELING: Combined with the massive vents; internal channeling forces air to flow over the scalp; providing remarkable cooling power.
  • PROGRESSIVE LAYERING™: Giro helmets with Progressive Layering™ use two different density EPS foam liners to address high- and low-speed impacts for more comprehensive energy management.
  • EYEWEAR DOCKING PORTS: Integrated eyewear docking ports with rubber grippers help to secure sunglasses.
  • REFLECTIVE DETAILS: Reflective Details enhance visibility at nighttime or in low-light conditions when illuminated by a light source; such as headlights; by returning the light back to the source and reaching the driver's eye.
  • ROC LOC® 5+ AIR FIT SYSTEM: This revolutionary fit system adds a new dimension to helmet performance by enhancing cooling as well as fit; comfort; and stability. Using a patented design that suspends the helmet just slightly off the top of the skull; Roc Loc® 5+ Air allows cool airflow to pass directly over your head; further enhancing the performance of vents and internal channeling that exhaust heat out of the helmet. Fit and feel adjustments mimic the Roc Loc® 5; allowing you to easily custom-tune fit tension and fore-aft tilt of the helmet in seconds using a single hand.
  • IONIC+® PADDING: Pure Silver is the secret ingredient that gives IONIC+ ® the power to provide natural; permanent odor protection to keep your helmet feeling fresh.

Color: Multicolor-4pack-a1, Size: Small
These are some of my favorite underwear. I find myself reaching for these constantly. They're very good quality and very stretchy. I'm 140 5'3 and I got a small they fit great. Someone larger or smaller would fit in the small too. I do stress that the leg holes are a bit tight on my thighs and I don't have thick thighs at all. On someone with thicker thighs I'd say size up to a medium. You can wear these as mid/high waisted or low waisted. They're versatile! The cotton gusset is a plus too❣️

Better than Haynes at for less money
Color: Multicolor-4pack-a1, Size: XX-Large
I am surprised by the quality of these knickers. They are better than Haynes for less money and when I say they’re better, I mean far better, but I can’t believe how comfortable and STRETCHY best underwear is

Color: Multicolor-4pack-a1, Size: Medium
like my daily driver now, like i never thought underwear could be this good untill now! have bought 2 4packd and will probably get more in the future :) they are snug but not suffocating, with my darker skin i was worried of them getting darker in that area but so far(3-4 months) they’ve been holding up well and clean easily in the washing with a bit of stain remover!

Satisfactory
Color: Multicolor-4pack-a1, Size: X-Large
If your wanting an easy on high waisted underwear these work. They are honestly strange material, a mix of three different things- not bad but different. Not seamless, might ride up, slightly on the thicker side. Will last a while. Comfortable enough but not amazing. Got for after a surgery and needed something different- these worked but would I get on a normal day probably not.

Super soft and comfortable!
I haven't bought new underwear in forever. I used to wear thongs, but now find them incredibly uncomfortable. The last few times I've tried to buy new underwear, the sizing was either way off (I'm a medium, but gave up after having to return them for a large and then extra large) or the quality was horrible (two brands stretch waaaay out and they can fall down while wearing them (I have larger ass-ets, so they shouldn't start to slide down during use). I tried these after buying some bamboo pyjamas and I love them! They are incredibly soft, comfortable, and stretchy. I can use them all day, and they work well, whether I'm lounging on the couch or wearing them under my spandex shorts at the gym, they don't ride up or slide down. They are both comfortable and look sexy, while providing support in all the right places. I haven't had them too long, so I can't speak on the durability, but they appear to be of good quality and I plan to order more, this time without the band.
