Help neede with clothing

Actually I need help with a shirt.

I hike in Patagonia Capilene 2 short sleeve shirts and when at camp like to switch out to a cotton Tee for around the fire and sleeping
My dilemma is the side seam on the capilene 2 when hiking, it starts to get itchy on the side seams just a bit above my waist. Any recommendations for a similar shirt without this seam?
I'm assuming the seam is designed for use with a Backpack.

Heres the shirt, note the seam.

Patagonia Capilene T

I really like the seam placement on these but I'm not spending 70 bucks on a shirt

Rab Merino 120

They had a Mass drop for 40 bucks but not in my size

I use the Outdoor Research Sequence Duo T in cool weather, and have never had an issue with itching due to side seams - but I don’t know if that’s due to construction of the garment, or just my own personal sensitivity level to such things. The bad news? They cost $50.

In the 90-degree, 90% humidity of an Ohio Valley summer, a merino-blend anything is just too hot, so I use the OR Echo series T-shirts. A bit of a used-Kleenex feel, but they do a good job of moving moisture away from me and letting it evaporate (or what passes for “evaporate” in such conditions.)

I have hiked in a Capilene 2 shirt (long sleeve) for years, no problems (in fact, it's the same shirt since 2007). That may be due to my being female and wearing a woman's shirt. However, regardless of gender, everyone's body is a bit different.

There are a number of other brands of synthetic base layer shirts around; I suggest getting thee to stores and trying on different brands! Don't neglect the athletic departments of big box stores, where you may find what you need for a lot cheaper than Patagucci! (I like Patagonia because of its conservation stance, butI would ditch my shirt in an instant if I had your problems.) Amazon has pages and pages of men's base layer shirts, but of course you can't see the seams without ordering.

The time I went off for a family backpacking trip leaving behind the clothes I planned to wear when hiking, my son loaned me an Under Armor shirt. That worked just fine.

I ike merino wool for base layers, but when it's exposed, it doesn't wear nearly as well as synthetic--which makes it even more expensive! And, as Glenn mentions, in Ohio humidity, just the thought of wool is enough to produce a third degree burn! (I just returned from a family wedding back there)

I ordered the Rab Merino from mass drop I got the Large. I'm not quite an XL but not quite a L either.

The main reason going for the XL is due to being a slim fit.
I have a bit of a belly and pretty broad in the chest area

The Capilene 2 shirts only bother me in that one spot but on both shirts, I have sissy skin, even a grain of sand or a wrinkle in my sock drives me nuts.

I usually wear a Railriders Therma-wool long sleeve shirt over top of the capliene 2

You would hope that expensive shirts have finished inside seams but that is not always the case. The inside seam should be flat and smooth. I have some Ibex light weight wool shirts and they have wonderfully smooth inside seams.

Three solutions:

1) just wear the shirt inside out
2) if you sew, buy some seam tape and cover the rough inside seam. Use the seam tape that has little folds on each side. Seam tape comes in both synthetics or cotton. Not sure the shirt is worth the cost of having a seamstress do this for you.
3) wear a very light smooth tank top, inside out, under the shirt, if you are freaked out by others seeing you wear visible clothing inside out.

When its hot i go for a simple dry fit shirt, and when its cold i go for a full selves thermal.

A little heads up for you...The Patagonia Capilene 2 has extra seams that run from front to back over the middle of the shoulders, which are absent in the Capilene 1, and when using a backpack, the weight of the shoulder straps will press onto these additional seams, making the Capilene 2 more uncomfortable to wear when hiking than the Capilene 1.
Usually, the lighter the hiking equipment is, the more expensive it is but although the Capilene 1 is a lot lighter than the Capilene 2 (80g vs 148g) it's actually about 10 Dollars cheaper!
The main problem with either Capilene is that they do not offer the wearer much sun protection...Only SPF 15-20.
After much research I went for the ultralight Rab Interval instead...It's 2g lighter than the Capilene 1, yet manages to offer SPF 35+ sun protection, and its about 10 dollars cheaper than the Capilene 1 (about £20 cheaper than the Capilene 2), so you can buy 2 Rab Intervals for the price of one Capilene 2!
