Chester Crew Neck (Bamboo) Undershirt

47 reviews
Regular price£34.00

This is a classic crew neck undershirt. If you wear your shirt buttoned to the top this is the style for you. The body is long so it stays tucked all day.

Our fabric is 95% bamboo viscose mixed with 5% elastane for a super-smooth, lightweight material that moves with you. You'll hardly notice you're wearing it.

We guarantee you'll love it or your money back.

So much better than a vest!

A great buy!

I've worn other vests (from typical high street stores) for years under my work shirts to prolong their life and improve my daily comfort. They worked quite well, but I can't say they were anything other than acceptable. Needing to replace some which had seen better days I thought I'd see if there was anything else out there that may be better, and I stumbled upon this site. Liked what I saw (and the thought of supporting a home grown business) and thought I will give them a go. Wasn't sure of the best fit for my size, I'm the wrong side of 40, just short of 6ft4, slim with a 34(ish) waist but with quite broad shoulders from my many years of swimming in my younger days. Pretty much exactly on a 44 inch chest, I emailed a question on what they thought would fit best and got a lovely reply from Yvonne who said I'd probably be ok in the XL but that at worst they would be able to refund/exchange if it didn't fit as I like. So I ordered 3 of the XLs. They arrived quickly with a personal hand written note, very impressive. The fit is definitely snug for me but not at all uncomfortable - I like the fact the vest is giving me a gentle hug. The material feels lovely on the skin and despite it being a thin layer, it really has kept me nicely warm while the weather oop north "remains somewhat chilly". I know this will sound silly, but I actually look forward to putting it on in the morning! Because of the good fit, it adds no bulk to my business shirt, which is also slim fit, and people have been commenting if I've hit the gym again and lost weight. Bonus! So, for me I'm absolutely pleased as punch with the purchase. It was worth paying that bit more for an undershirt of this quality. Hats off to Robert Owen (and Yvonne), I'll be coming back for more when I need them, thank you!

A Second Skin

I am pleased with the undershirt and this is my second purchase. The fit is perfect and the material is soft to the skin. I have no idea how the garment will fare after multiple washing etc., but I hope for the best.

Splendid product

Very comfortable to wear under a formal shirt. Barely know that I am wearing it. Regulates body temperature nicely in cooler environments. Hopefully will be as efficient in warmer climes.

Snug as a bug

I reload on these wonderful undershirts every year and now my wife has caught the bug. They are wonderfully soft, snug fit and form a brilliant base layer when out with out labs and are also just the ticket when indoors with the heating turned down a tad! Magic.Thank you Robert and Yvonne.

Chester Crew Neck (Bamboo) Undershirt

I bought this undershirt for a funeral and after a full day in 33+ heat in a suit my dress shirt was completely dry which surpassed my expectations of what the undershirt could do. I was very impressed that my order arrived within 24 hours of placing it and the handwritten note was a nice touch. Shirts are usually too long for me and this is no exception but the material is so light I didn’t notice it at all. The shirt is very comfortable and worth the price, and though buying more than one is sadly out of the price range of a student right now, I will be definitely be buying more at some point and will be recommending them to others.
