Blank T Shirt Quality – What is Gsm?

Best Blank T Shirt

Hello there, the fact that you are here testifies that you must be in a dilemma for which quality blank or plain t shirt to use for your clothing brand or you might be browsing for fun. Anyway, whichever it is we are always here to help.

So, the main question would be what quality would you like to provide to your customers. Are you looking for something cheap or you want to build something so that customers keep returning for more. We normally suggest and want to work towards the second case.

Round Neck T Shirts – The most commonly used t-shirts are made of 100% Cotton. These days many brands are providing various blends but 100% cotton has always been the best choice.

In cotton tees, you might have heard of GSM and wondered what that is, well, GSM basically means Grams per Square meter. Essentially is means how many grams does one meter squared of fabric weigh. This is the preliminary factor when checking the fabric quality. However, THICKER IS NOT ALWAYS BETTER. Please read the previous sentence and understand it well. We normally get clients asking for a thicker material of comparing materials based only on GSM. So i repeat THICKER IS NOT ALWAYS BETTER. Still GSM is the preliminary measure of quality.

Varieties of GSM

1- 90 GSM – 120 GSM – These blends are not normally available in cotton and we only have these in polyester. They are used only for promotional purpose, Marathons, Rallies etc. Normally, they are sublimated upon and worn on top of regular wear and usually thrown after the event.

2- 140 GSM – Next in line is 140 GSM. We have this available as jersey cotton t shirts. These are also for promotional purpose. And mostly used for baby wear and inner wear by clothing lines. Our 140 Gsm Cotton T Shirts are made of RingSpun Semi Combed Cotton. Combing is a process through which excess fibre is removed from fabric. We shall talk about combing in detail in a separate post. Stay Tuned.

3. 160 GSM – This is the starting point of regular wear tees. The classic light weight T- Shirts are manufactured at this weight. Our 160 Gsm Tees come in 2 varieties – Combed and Semi Combed. We always suggest the combed variety to our partners.

4. 180 GSM – This is the GOD Father in Jersey T Shirts. It is the most widely used variety throughout the world. It refers to the 5.3 Oz tee. It has just the perfect thickness. Neither too thin that it feels cheap Nor is it so thick that its hot and uncomfortable. It’s just perfect. All brands mostly have this variety in most of their lines. Coming to processing. We make 180 GSM in Semi Combed and Combed Variety. We also offer a third variety which is Combed  + Biowash/Biopolish. We rarely deal in Semi Combed unless on make to order. Our most selling tees are 180 GSM Combed (with or without Biowash). Coming to biowash, its a process that is so important that we shall dedicate a separate post to biowash. However in brief – Biowash uses enzymes to remove stray fibres giving the smooth of premium fabric.

5. 200 GSM – This is the most premium fabric used by top end brands. We only keep the Combed and Biowashed Variety in this Weight because its no use buying a high end quality without biowash. 200 GSM Biowashed tees have the utmost soft feel and premium look. And they last long as well. These are 5.9 OZ heavy weight tees.

After studying the above fabric qualities and their properties, we might have been able to bring some light to the equation. But fabric qualities being so complex, GSM alone can’t decide the best tee, we have to look at various factors like Post Processing, Washing, Dyeing, Yarn Count, Stitching etc.

I think I shall say good bye here for now, Hope to meet you in our next post in which we shall discuss more factors that go into the quality of a t- shirt. See you soon.
