Craft Arm Warmer 3D, £25
Unlike many standard arm warmers, this pair from Craft features a variety of different fabrics placed in different positions, thereby moulding to your arm and regulating your temperature more effectively.
They are thicker at the back and around the elbow than around the front, which helps keep your arms warm but not clammy, and you don't overheat in them; a common problem among arm warmers.
There were the usual silicon grippers around the upper arm, but our tester found the arm warmers to be quite long - whether you choose small or XL, they're the same length - which may mean you'll need to roll them up. There is no extra-reflective piping and they are not waterproof or windproof, but they dry quickly and are warm.
Santini 365 Arm Warmer, £24.99
The fleecy feel of the lining in these arm warmers makes them very cosy and comfortable to wear, but also too warm for anything other than late autumn or winter cycling.
They are a straight cut, but because of the comfort and stretchiness of the material, they fit just as well as any ergonomic pre-shaped arm warmer. The grippers (top and bottom) work perfectly to prevent slippage (even for our skinny-armed tester).
The only fault we found is that the material doesn't dry as quickly as some others, but it's not a major gripe as it remains perfectly comfortable even when damp. They feature a minimal amount of reflective piping but the bright red colour means they easily stand out when you're cycling in heavy traffic.
Pearl Izumi PRO Leader Arm Warmer, £29.99
These arm warmers are a classy piece of kit that can be worn on the bike or run. The combination of aero panels and Thermal Lite fabric make them effective and fast.
On a long run in conditions that ranged from cold and windy to hot and showery, the sleeves worked beautifully throughout. They stayed put, thanks to the elasticised grippers, and kept arms warm and comfortable. After a brief downpour, they dried quickly too.
Our tester's only minor quibble was that they gripped so well they were a little hard to roll down when the sun came out. On the bike they were equally effective, and the silicone on the upper arms gripped well on the move. These sleeves look and feel really premium and do a terrific job.
Saucony DryLete Arm Warmers, £20
Aside from the fact that they turned a few heads, presumably due to the colour rather than our tester's speed on the bike, these arm warmers served their purpose well.
The upside of the bright pink colour and reflective branding is that motorists should have no problem seeing you in the fading autumn daylight. And,
as our tester found, may even generate an admiring beep or two.
Performance-wise, they offered a particularly snug fit - so try before you buy to find the perfect size - and are long enough to reach from armpit to wrist. Arms stayed toasty and dry, and with excellent elasticity, you won't feel your movements restricted in any way. The balance of windproof yet breathable material should keep the arms from sweating when your temperature rises.
SUGOi Sakura Arm Warmer, £25
Sugoi is well-known for its wacky arm-warmer designs (we loved last season's colourful 'tattoo' style). And while the Japanese-inspired blossom graphics might not be to everyone's taste, the great practical features should generate plenty of fans.
The arm warmers were warm and comfortable on chilly autumn mornings thanks to the fleece-lined MidZero stretchy fabric. The thermal material wicked sweat well and dried quickly after wet weather. They aren't pre-shaped but still offered a snug fit and the silicon grippers on the upper arms worked well to keep them in place and prevent drafts.
They're a simple but effective piece of kit that will add versatility to your cycling or running wardrobe, and may even garner some admiring glances.
