Some of these comments are for the Sigma pullover, which this Jacket replaces.
"Warm. Perfect fit. Arms even better fit. Total mobility. Instant loft like a down jacket. The Hood saved me from having to buy a down hat to sleep in. Quality stuff."
— Tony Swallow.
"It's winter. Client is very, very cold despite wearing all her spare layers. Problem. I give her my PHD Sigma to put on. Client gets warm. No problem. Yours, thankful for the incredible performance from your nanogram gear."
— Tony Halliwell (MIC).
"Very warm for its weight. Reasonably small pack size. The armholes are bound by lycra to give a close fit, as are the pockets. Small, but very nice detail."
— Ross Evans on Outdoorsmagic Forum.
"Just a quick note to say after a month or so deciding which smock to buy, PHD, RAB etc. I plumbed for the Sigma and how happy I am with it. I can't wait to test it but if it performs as well as it looks and is made, which I'm sure it will, then I will be very happy."
"The Sigma pullover has arrived, and like everything else I have had from you is excellent."
"Not a query; rather a big thank you. Received today my Sigma pullover. Mightily impressed by the materials, build quality, light weight, compactness and elegantly simple design. I also have a Sigma vest in a larger size which fits into the top pocket of my rucksack and is so quick and easy to slip on at winter belays."
"Many thanks for my Sigma pullover which arrived yesterday ... I have been unable to take it off this morning - walking across the fields in below freezing frosty conditions, then cycling into town to do some shopping. I have been toasty warm with just a shirt underneath, and it makes me feel like a million dollars. It is so well made and thought out - I have just discovered the zipped security pocket - what a brilliant touch! It was meant to be Christmas present from my wife - but she is away at the moment and I just couldn't wait to use it. A fantastic start to Christmas!"
"Today I've received the Sigma jacket and I am very, very pleased with it - (roll on winter because this is so lightweight it's unbelievable)."
"Thanks for the two Sigma Pullovers. The pullovers were Xmas presents, and went down very well. They wouldn't take them off!!"
