Last fall I bought 9 long sleeved rib-knit tee shirts from Lands End and put them in rotation with six other tees of the same type. I wear them a lot for very casual wear, and even sleep in them sometimes. I just found holes in 3 of the new tees. The holes are in the body of the tee, just below where the sleeve is connected to the body of the shirt... in other words, in the armpit. I have not found holes in any other items

Last fall I switched to using Certain Dri deodorant, which was recommended by several members of this forum. Has anyone had a problem with Certain Dri causing holes in garments? This seems unlikely, but I thought I should ask. Or is it more likely that the tees are made of really inferior fabric? They seemed fine when they first arrived.

Wasn't there a thread recently on tee shirts? Unfortunately I've been very busy and didn't have time to read it. Could someone tell me where to find it since it seems I may be switching brands.

Thanks very much for any advice.
