PowerLayerCompression Tops for Men and Boys Base Layers Men Running Top Thermal Shirt

I bought this primarily for a base layer when riding (electric scooter). In winter, it's important to use multiple layers to ensure you have sufficient air pockets which can help hold heat but without feeling like you're overheating due to unbreathable layers. In summer, it's important to minimize layers but ensure you have sufficient airflow without giving up protective gear.This top is fantastic as a winter base layer. It keeps enough heat in but allows air to cycle in as you inhale and move. It's very stretchable, but I advise buying the size that is correct for you according to the sizing guide. On a few of the colder days, I've opted to wear this even while indoors because it reduces how long I need to have the heating running.I could even suggest this might be comfortable for sleeping. Since it helps keep heat in but still allows air to circulate when you inhale and move, it may be ideal for helping to maintain body temperature while sleeping.

I use this for playing golf in Scotland when the temperature is in the low single figures. It does the job well, stretches off nicely after a few wears and watches and is cheaper than big brand names.

When I opened the package I thought I'd been sent a child's size however the material is very stretchy so definitely compression!

Son says it's comfortable.Bought M size, and it fitted perfectly.I think price should be less.4 stars for price.

Got these items quickly and in good order, only problem was they are very tight, exposing all the bits Idid not work on!. The XL just fitted ( and would malke someone a good miniskirt!). Maybe after another 6-months of workout they will just fit.

Stretches ,fits well ,warm comfortable, well made

A perfect base layer for doing tai chi outside in the colder weather. Excellent muscle support and great thermal qualities.

I'm six feet tall and have a 43 inch chest as measured with a tailors tape measure on exhaling...just to be precise! The large fits me really well, so the size guide supplied by the seller seems to be accurate. The fit is skin tight with a degree of compression, and whilst perfectly comfortable it does provide a supportive feel which I quite liked. I wore it under a running t-shirt today and whilst I can't attest to anything more technical than it being snug and supportive I did like the overall feel as I've not worn one before. I think maybe going a size up may be more appropriate if you intend to use it as a more general base layer - under your dog walking fleece, perhaps - though the fit is definitely comfortable given the degree of compression.Just wash it on a cool cycle, if it shrinks you'll never get in on never mind off and there's a knack to this as well. Feed your arms through the both sleeves, slide the garment up your arms and then pop your head through the hole. I don't mean to be patronising here, but if you try and put it on like a jumper you may get trapped and have to call the fire brigade with your partially free arm, your extremities taking on a purple tinge all the while due to restricted blood flow. The last thing you want is Red Watch turning up with bolt cutters to free you from your new top, or thinking you have a strange Lycra fetish...Like I say, the fit is supposed to be tight and supportive, but not remotely uncomfortable.
