True to size and great quality
Size: X-Large, Color: Colony Blue Melange
This shirt fits true to size. It is very soft and comfortable. The fabric is a thinner fabric that can be worn over dress shirts. The quality of the shirt seems to be very good. I have bought these pullovers in multiple colors, and they all seem to be consistent with the quality and size.

Received the wrong size
Size: X-Large, Color: Navy Melange
Seemed and looked like a decent quality shirt. A little lighter weight than I expected. I ordered an XL, but received a Large, which did not fit. Returned it and bought a similar shirt in a different brand.

Beautiful color
Size: Medium, Color: Red Melange
I loved the vibrant color of this shirt. The fabric is lightweight but not sun shirt/rash guard material. This will add a layer of warmth for seasons when the temperature fluctuates greatly during the course of the day. The sizing chart was accurate. My husband generally wears a medium but, based on the size chart, I bought him a large and it fit well.

ASICS Gel Running Shoes – Comfortable, Lightweight & Perfect for Gym and Running
Size: 10.5 X-Wide, Color: Black/White, Size: 10.5 X-Wide, Color: Black/White
I recently tried a pair of ASICS Gel sneakers, and I’m really impressed. They are extremely comfortable, with great cushioning that makes a big difference during workouts. I’ve used them both at the gym and for running, and they perform very well in both situations.
The support is excellent, and they feel stable without being too heavy. I especially like how they absorb impact when running, which helps reduce stress on my feet and knees. They also have a nice fit and feel breathable, so my feet don’t get too hot.
Overall, I’m very happy with them. If you’re looking for comfortable and reliable sneakers for the gym and running, I would definitely recommend ASICS Gel shoes.
