DESCRIPTION

PRODUCT DETAILS

The Nano Flex 3G fabric used across these arm warmers utilises a combination of newly updated durable water repellent (DWR) treatment and mechanical heat treatment to give previously unheard-of levels of rain protection. Light rain beads off the fabric, keeping you dry when those inevitable rainy spells descend.

On the inside of the Nano Flex 3G fabric, a super soft finish and the optimal loft have been achieved through Castelli’s meticulous research and development. The fabric feels phenomenally comfortable against the skin and the loft traps just the right amount of air above the skin to keep your heat regulated over a wide range of autumn and winter conditions.

This latest update to the Nano Flex fabric not only reflects Castelli’s ongoing commitment to offering you the very best garment quality but crucially means more time enjoying yourself on the bike.

The flat-lock stitching and single-seam construction keep the profile of the warmers low and the stretch is optimised for maximal freedom of movement. A dual-sided silicone gripper at the upper end secures the warmers in place. The compact size of the warmers makes them easy to stuff into rear pockets when conditions lighten up.

Key Features

Newly updated Nano Flex 3G fabric for exceptional warmth, softness and protection from the rain
Minimal seam construction for aesthetic versatility and freedom of movement
Easily packable into a pocket
Highly breathable
Optimal temperature range is 8˚C – 20˚C

SIZE GUIDE

Castelli Warmers Size Guide

Jersey/Short Size	Your Weight	Suggested Warmer Size
XS-S	45-60KG	S (WOMAN)
S-M	45-60KG	S (MAN)
S-M	60-70KG	M
L-XL	70-80KG	L

Castelli warmer sizing relates to your jersey or short size and your body weight.

Warmers have a lot of stretch and for designs incorporating Thermoflex fabric, you can size down.

However, we would not recommend sizing down for Nano Flex and Nano Flex Plus products.

HIPS - CM	87	92	97	102	107
INSEAM - CM	75	76	77	78	79

Castelli casual clothing is designed to give a loose fit when correlated to your jersey size. So if you wear a Gabba in L, you will achieve a casual loose fit with a L-sized T-shirt. Bearing this in mind, if you prefer a closer fit you may wish to size down.

For shorts and trousers, please select the same size as you would for bibshorts or tights. Women's T-shits and hoodies are designed for the female form. All other casual pieces are designed to be suitable for both men and women.

The Light Bra is designed for A and B cup sizes only. The Bellissimo bra is designed for B and C cup sizes only. The Support Bra is designed for C and D cup sizes only.

Please note these are cycling bras and are designed to offer light support and maximum breathability on a bike. They should not replace a sports bra for high impact sports.

To determine your frame size measure under the bust as indicated. To calculate your cup size measure around the fullest part of the bust. If the difference is less than 15cm, you will require the Light Bra. If the difference is greater than 15cm but less than 20cm, we recommend the support Bra. If the difference is greater than 20cm we would recommend you buy a commercially available sports bra.

CHPT3 Size Guide

CHPT3 – Tailored Sizing (pre-2020)

Chest	Inch	CM	Waist	Inch	CM
A - 36	36	91.5	B - 29	29	73.5
A - 38	38	96.5	B - 30	30	76
A - 39	39	99	B - 31	31	78.5
A - 40	40	101.5	B - 32	32	81

A - 42	42	106.5	B - 34	34	86
A - 44	44	111.5	B - 36	36	91

CHPT3 clothing uses a tailoring system for its sizes. The physical chest or waist size is used as the garment size. If you have a 40" chest, you will need a 40" jersey. Please note that while the CHPT3 range is not designed for racing, it is still a close fitting athletic design suitable for active cyclists.

CHPT3 - 2020 range onwards

	A - Chest	B - Waist	C - Hips	D - Inseam
XS	88cm	76cm	90cm	81cm
S	92cm	80cm	94cm	82cm
M	96cm	84cm	98cm	83cm
L	100cm	88cm	102cm	84cm
XL	105cm	93cm	107cm	85cm
2XL	110cm	98cm	112cm	86cm
3XL	115cm	104cm	116cm	87cm

Men's and unisex Castelli sizing is based on your physical measurements and the garment's intended use. Race items are designed to use fabric stretch to achieve a very snug fit; as such physical garment sizes vary within the range. Please don't compare sizing with other manufactures. The sizes shown above are for the maximum size, so someone with a 99cm chest would be a size L. If you have a 101cm chest then you're an XL.

Sidi fitting guide

Like many handcrafted Italian shoes, Sidi cycling shoes feature a slim fit, the equivalent of a ‘D’ width. In our experience, if you’re usually a 45 in cycling shoes, you’ll be a 45 in Sidi shoes.

However, you also have the option of Sidi’s half sizes. These use the same length soles as the main size (i.e. 45 and 45.5 are the same length) but use a larger volume upper. This is perfect if you need a touch more width, have slightly higher arches or use an insole that takes up some of the volume of your shoe.

The volume and fit of the shoe is also affected by the closure system utilised. We’ve found that the combination of a central dial with the Soft Instep 4 strap means the Sidi Wire 2 has a slightly roomier toebox than the rest of the range, making it ideal for those seeking Italian styling with a little extra wiggle room.

If you need more volume, Sidi’s range of Mega fit shoes feature soles that are 4mm wider and have larger uppers for those with higher volume feet or deep orthotics.

Of course, everyone’s feet are different and slipping the shoes on will give you the best idea. We’d recommend trying them on towards the end of the day or even after a long ride to give your feet a chance to swell to their maximum size.

If your toes are brushing the end of the shoe, they’re too small. If you stand on tiptoes and the heel of the shoe doesn’t lift with the heel of your foot, creating a gap, they’re too big.
