Troy Lee Designs - D4 Polyacrylite Block Helmet (MTB)

D4 Polyacrylite Block Helmet is a Troy Lee Designs mountain bike helmet built for enduro and bike-park riders. The D4 platform is known for downhill-focused coverage and a locked-in feel when the terrain gets steep and fast. The Polyacrylite shell helps keep the price more approachable while still delivering the coverage riders expect. In the Block colorway, it brings a strong visual identity without losing the performance-first focus of the helmet.

The fit is aimed at riders who need their MTB helmet to stay composed on technical descents while still feeling comfortable during transitions, climbs, and longer days outside.

Why We Like It: it gives riders a stable feel on rough descents without turning every climb into a chore.

Why It’ll Work for You: For riders comparing mountain bike helmets, this one makes sense for technical trails, gravity runs, and all-day pedal missions where comfort still matters.

Variants / Options: multiple sizes and colorways available; check the selector for current stock.

Halo patches
I tried the Halo Dot Ultra Thin Pimple Patches, and overall I’m really impressed with them. In terms of effectiveness, they work well at helping bring pimples to a head and protecting spots overnight so they don’t get worse or irritated. The value for money is good since you get a decent amount in the pack and they’re thin enough to use during the day or night without being too noticeable. They’re super easy to use—just clean skin, place the patch, and go—and I like that they stay in place pretty well. I also find them pretty versatile, since you can wear them at home or out and about if you get a discreet one. For skin sensitivity, they’ve been gentle on my skin with no irritation, which is a big plus for me. Overall, they’re a simple, effective skincare staple I’d definitely keep on hand.

Nice patches -- Fair price -- has sulfur!
This is a review for the Halo Dot™ Pimple Patches for Face, Hydrocolloid Acne Patches with OptiMSM®, Visibly Shrinks Zit & Whitehead- Comes with Travel Essentials Inner Pouch (33 PATCHES) ($12.59) PROS: Price -- a fair deal for 33 patches and consistent with pricing of most other similar patches online. The inclusion of sulfur (this OptiMSM business) makes these unique also -- I can't seem to find others on Amazon with similar formulation, so these are intriguing. Sulfur is known for antimicrobial properties and can be helpful for zits and a little bit gentler on your skin than benzoyl peroxide or salicylic acid -- but anytime I put any sulfur stuff on zits that are above or around my eyes, it seems to migrate INTO my eyeball while I'm asleep and man is that uncomfortable. This little patch solves that dilemma nicely by keeping the sulfur put. CONS: none that I can see; these are a nice entry into the hydrocolloid acne patch space.

Disappointing results and poor adhesion.
I love Hydrocolloid pimple patches. I have used at least half of the brands available for sale and even the non brand ones. I’ve also used the hydrocolloid sheets and cut them to size and the hydrocolloid gel bandaids and used for pimple patches. I love how they help along the healing and keep me from picking at the pimple. This brand I wasn’t impressed by. None of them stayed on my face for half the night. The one that remained in place the longest out of the 4, didn’t show any signs of improvement. The longest they kept in place was 3 hours. I had to reapply and I still handbrake noticed any signs of healing after using one full sheet on 4 smaller sized blemishes because the adhesive wasn’t working.

Stops Me From Picking and Actually Works
As a woman in my 40s, I never would have guessed I’d still need pimple patches, yet the occasional zit still pops up — and these things are like magic. They work really well, blend into my fair/light skin nicely, and are barely noticeable at a quick glance. I’m also a terrible picker, and picking is so bad for your skin, so I love that these keep me from messing with pimples while doing all the work for me overnight. I’m always grossly fascinated by how much gunk they pull out by morning. Very happy to have these in my little skincare emergency arsenal.

Camouflages well with the skin and sticks long enough
I was excited to try these Halo Dot patches because I was having some breakouts before a wedding I had to attend. I put these on three nights before the wedding only at nights and left them on until the morning. I washed my face the 1st night, yet the second night I did not and it still attached (mind that I have a very oily face by the end of the day). With every application I saw good results as the breakouts were being reduced with each use. It is easy to put on and to carry out if you need to travel because it comes in two separate little envelope like package that you can put in a backpack/purse. These are thin and are almost not visible.
